What are the advantages of external fertilization?

A large quantity of gametes can be fertilized at one time, possibly leading to a larger number of offspring. Furthermore, external fertilization ensures the wide dispersal of offspring (by the ocean currents), thus resulting in less competition for resources such as food and living space.

What are the advantages of internal fertilization?

internal fertilization is, by definition advantageous because it is natural. In Vitro fertilization is advantageous for those who cannot have children naturally because it allows the miracle of birth to occur.

What is in chemical fertilizers?

Nitrogen, Phosphorous, and Potash with a variety of other trace elements and metals. This is also know as the analysis. Look on a box of 'Miracle Gro' the next time you are at the store. You'll see 3 numbers together, they represent the % of Nitrogen, Phosphorous, & Potash. (Urea is a form of a nitrogen rich fertilizer made from synthesizing ammonia -- which is a gas -- with carbon dioxide; another commonly used form of nitrogen fertilizer, especially in the US, is anhydrous ammonia.) The 'chemical' fertilisers contain the same chemicals as in 'natural' fertilisers. It's just a bit more convenient to sprinkle in the 'chemical' ones than digging in a wheelbarrow load of manure! Answer II Different chemical fertilizer have different chemicals as Urea , DAP contains di ammonium phosphate and so on .

Advantages of artificial fertilizer?

They are chemically cheaper to mass produce than natural fertilizer. Honestly, the advantages of Organic Agriculture far surpass the price differential. I use pulverized sea shells and sea water as fertilizer, and it is quite literally like "Miracle Grow."

What are the advantages and disadvantages of chemical fertilizers?

Advantages . Chemical fertilizer can be made much faster unlike the natural fertilizer . It has much more NPK, usually around 20 to 60 percent, natural fertilizer usually only has a max. of about 14 percent . If it is made according to the soil that it will be used on, it will do nothing but grow a healthy plant Disadvantages . Puts acid in the soil . Strengthens pestecides(they become stronger and more resistant to chemicals that should keep them away) . Other than NPK it contains inert filler and maybe some unnesesary chemicals . It has very little carbon which is a key element in plants . It has no energy, so it can only help the plant when there is enough organic matter around from where it can get the energy, otherwise it burns the roots and destroys the plant . Chemical fertilizer also get a lot of water out of the soil which it contaminated and therfor pollute water . It degrades ecosytems . It releases a green house gas called nitrous oxide So in total, chemical fertilizer is worse than natural fertilizer this site below helped me a lot, also for pros and cons about natural fertilizers http://www.malcolmbeck.com/books/gv_method/FertilizerOrganicNaturalversusChemicalInorganic.htm So what is the advantages and disadvantages of fertilizers ? Most plants, especially modern varities, will pull more fertilizer molecules out of the ground than what is naturally resupplied. In a forest, the decomposing leaves and bark will feed the soil and give ferns (growing below the trees) enough fertilizer to live on. However, in a garden where you grow vegetables or flowers, these plants typically consume large quantities of fertilizer.. higher amounts than nature can naturally resupply. in order for the plants to grow properly, they need the right amount of fertilizer available in the soil. If there is too little, growth may be stunted and flowers and fruits may not develop properly. The plants become suceptible to attack by insects and disease. A plant which is fed well is often able to survive better. This is the same with humans: people who are starving is often plauged by disease compared to people who get all the nutrients they need. Therefore the gardener must manually fertilize the plants to ensure they have enough food to grow on. Plants which are fertilized often are bigger, stronger and produce more fruits and flowers than plants which are not fertilized. Fertilized plants are generally often also more disease resistant than unfed plants. There really is no disadvantages to fertilizing, and most home owners should fertilize plants such as vegetables, fruits and flowers because these - persumably modern hybrids - tend to consume much more fertilizer than nature can provide.. This also goes for lawns, for example, which has individual grass plants growing very close together - much closer than grass plants would in nature - and therefore have to compete with each other for nutrients. However, if you give TOO MUCH fertilizer the plants can suffer just as they would if they get too little. For example, both magnesium and calcium molecules are needed by the plants, but given too much calcium, for example, can interfer with the plants ability to take up magnesium and the other way around, too. If you add fertilizer to certain plants when the soil is dry or the temperature is very hot, you also risk damaging the plants. While there are no specific disadvantages to fertilizing if doing it correctly, you do need to know approximately which type of fertilizer (which nutrients) the plant require, how much to add, and when to add it. It also needds to be watered in to avoid that the plant dies from thirst (plants which grow in fertilizer rich soil without water will cause water to exit the plants and kill them).

Advantages of internal and external fertilization?

External fertilisation allows plants to reproduce without them having to touch each other. This means that the plant reproduction is more efficient. Internal fertilization is a natural process and it is possible with compatible gametes only whereas in external fertilization we can manipulate with uncompatible gametes also.

What are all the advantages of bio fertilizers over normal fertiizers?

There are major advantages of using bio fertilizers over normalfertilizers. These bio fertilizers are part of nature and are notchemically bound to kill animals and other plants.

What are advantages of internal fertilization?

\nthe chance of the gametes (egg and sperm) meeting are greater so the chance of fertilization is increased.

What are the advantages of biological control over chemical control for prevention of plant diseases?

Biological control takes more roll in Integrated pest Management system where we are adopting the natural based methods inclusive of of Mechanical, Physical, Agronomical control methods, besides the Bio-control methods. comparatively the chemical control methods led to the following adverse effects which can be prevented by adopting Bio-control measures. 1.Creating Resistance power on Pests 2. creation of resurgence power , 3, poisoning the plant products(Foodgrains, fodders like straw) so that it make ill effect on human's and live stock's health 4. polluting the Air, Water, Soil, 5. Chemical control Very expensive than Bio control methods

Advantages of using Artificial fertilizers?

it helps it large amount of production of products. a much better quality and cheaper price. it makes benefit for the farmers who has much invested in their crops.

What Two advantages of external fertilization?

1) Organisms that reproduce externally produce a lot more offspringcompared to internal fertilization, for example frogs reproduceexternally and the female releases up to thousands of eggs whilehumans release only one egg from the ovary to be fertilized. 2)Reproducing externally is faster and requires less dependency onthe parents for they are not physically attached to the parents.

What advantage is there to preventing self-fertilization?

Preventing self-fertilization- flowers have a number of adaptations to limit self fertilization. Some flowers are self-incompatible, meaning that the female part, Carpel, will not accept its own pollen. Other flowers are dioecious , having separate male and female individuals, which makes self fertilization impossible. Some are monoecious, having separate female and male flowers on the same plant and their male and female flowers will mature at different times. Some flowers will make their stigma receptive to pollen only after all of its pollen has been shed. Some flowers keep their stamens and pistil at a distance from each other, for instance the pistil may be vary tall and the stamens may be short, making it harder for the flower to pollinate itself.

What are the chemicals in fertilizer?

It depends on the specific type, but chemical fertilizers often contain ammonium nitrate and/or phosphates.

What is the advantage of external fertilization?

An advantage of external fertilization is that it produces a largenumber of offspring. In external fertilization the sperm cellunites with an egg cell in the open.

The advantages and disadvantages of chemical fertilizers?

Advantages of Chemical Fertilizers:- We need more food to feed increased population. This is only possible through high yielding varieties of food grains and other food materials like Oilseeds, Sugar, Fruits etc. All these things need nutrition through roots - from soil. These nutritions in large quantity can only be fortified to soil through use of Chemical fertilizers. Organic - manuring is just not possible because of many limitations. Disadvantages of Chemical Fertilizers:- Excess or uncontrolled use can spoil the soil properties, Osmotic pressure, pH, Conductivity and water holding capacity. It may also affect adversely on population of microorganisms and other parameters.it can also damage water resources

What are the advantages of bioprocess over chemical process?

the main advantage is,. less cost . easy down stream proceesing . the nature of the product is non toxic

What are the advantages of using natural fertilizer?

Slow acting but good for the environment, the plant and the soil may be the respective disadvantage and advantage of natural fertilizer. The main disadvantage of natural fertilizers is their slowness to release, and to act, in soil. Non natural fertilizers focus on improved yield, natural on improved soil and plant health. Specifically, natural fertilizers focus on soil structure. They improve structure by their attention to the total nutrient picture, soil pH, and organic matter. If one of the nutrients is off, then the entire soil health is affected. If the soil pH is incorrect, then nutrients such as iron and magnesium may be present in the soil in adequate amounts, but they'll be unavailable to the plant. So natural fertilizers may be slow, but they're more environmentally friendly, in the short and long terms. Since natural fertilizers don't contain very high concentrations of nutrients, a farmer may need to use incredibly large volumes in order to maintain soil fertility (possibly several tons per acre). Less Environmental Problems

What are the advantages and disadvantages of organic fertilizers?

Advantages of organic Fertilizer! . Organic fertilizers are excellent for the soil. The organic matters in such fertilizers are essential for microorganisms, which build up the soil rich in humus. . The organic fertilizers release the nutrients in a slow and consistent rate that the plants can utilize. Since the microbes break down the materials, there is little risk of over concentration of any element. . The plants are provided balanced nutrition because of the presence of a broad range of trace elements. . Organic fertilizers are safe for all types of plants and there is no danger of burning due to salt concentration. . Organic matter binds to the soil where the roots can access it. So, it is long lasting as the organic fertilizers do not leach out. . The fertility level of the soil can be maintained with less work once the healthy soil condition is reached. . There is also less risk of over stimulation. Organic fertilizers do not lead to exceptional growth, which can lead to a variety of problems. The plants grown on organic fertilizers have a controlled growth. . Organic fertilizers also make the plants stronger to resist disease and pest attacks. Plants fed on organic fertilizers are also able to resist the advance of weeds and other parasitic plants. Disadvantages of organic Fertilizer . Organic fertilizers release the nutrients in a slow manner as in some cases the cooler soil temperatures hinder the release of the elements. . Organic fertilizers are dependent on microorganisms to break down the organic matter. If the soil is deficient in these beneficial microbes then the plants cannot get the full benefits of the organics. . They are very expensive compared to the same amount of chemical fertilizers. . Some types of organic fertilizers are difficult to apply in large areas. As a result, they are less convenient. . Organic fertilizers are difficult to get in some areas and also they may not be available in large quantities. Depending on the locality, the choice and blends of the organic fertilizers may be offered in limited quantity.

Advantages and disadvantages of nitrogen fertilizers?

Advantages: When soil has no more natural supply of nitrogen, the fertilizers give nitrogen back to the soil. Disadvantages: Any nitrogen that isn't absorbed leaks into water supplies and creates large growths of algae, which can be harmful to other aquatic species.

What are the advantages and disadvantages of natural fertilizers?

The advantages of natural fertilizers would be that they are notmade of chemicals and not harmful for the body. A disadvantage isthat they smell bad and don't work as well.

What are the advantages and the disadvantages of synthetic fertilizers?

Advantages Faster growing times and more products tend to be the advantages of using artificial fertilizer. Specifically, the artificial fertilizers tend to be called 'NPK' fertilizers. That's because they're high on nitrogen [N], phosphorus [P], and potassium [K]. The three nutrients respectively are responsible for root development below ground, shoot growth above ground, and flowering and fruiting. That's why putting 'NPK' in the soil jump starts overall plant growth and favors greater harvests. Disadvantages Improper use can contaminate soil for years and the nutrients can be lost in runoff water, causing water pollution. They can also be expensive, though good farmers only apply enough to reach the point of diminishing returns. Some have suggested that synthetic fertilizers might contribute to loss of soil structure, but numerous studies have shown that tillage practices and the consequential loss of soil organic matter are by far the primary cause.

What are the advantages and disadvantages of in-vitro fertilization?

studies have shown that ivf children can have long term hospitilizations or surgerys Pro: for some people, the only possibility to bear their biological child.Cons: cost (usually not covered by insurance); likely need to repeat attempt at ivf several times; invasive physically on the woman; possibility of lab mixups (there have been cases of the wrong sperm or eggs or embryo being used for the wrong patient); ethical concerns over the creation of excess embryos or their destruction; time and effort and stress spent on a gamble.Con-counters: cost compared to adoption may be comparable depending on your criteria and how successful you are (at either ivf or adoption); ethical concerns can be kept in mind when attempting ivf, by not creating more embryos than you intend to have transferred into your uterus, and if any are left, you can donate them to other couples to use.The underlying weight of either the pros or the cons will depend on one's beliefs, intentions, comfort levels with the alternatives, financial well-being, and seeing eye-to-eye with one's partner (if any). P ros- . It is by far the most effective treatment in order to bear a child if you are having difficulty conceiving naturally. . You can genetically test embryos prior to pregnancy and avoid genetic diseases. Cons- . Women who go through IVF are usually at risk of a condition called ' ovarian hyperstimulation'. . IVF is a very expensive, stressful and time consuming method of conceiving. . IVF ups your chances of a multiple birth.

What are the advantages and the disadvantages of using fertilizers?

That they give plant's nutrients that may not be accessible within the soil but that they hurt the environment are advantages and disadvantages of using fertilizers. Specifically, the soil sometimes has the correct amount of nitrogen, but not in the form that can be used by the plant. Fertilizers offer nitrogen in the proper amount and in the proper form. But they provide nutritional help at price. Side effects range from dependent plant growth and depletion of soil fertility to loss of soil food members and polluted runoff into area water bodies during rain events.

Why biofertilizers not popular?

The reasons include: . Their response in soil is not so quick as that of chemical fertilizers . perish ability i.e. low shelf life . very little awareness among farmers . the strain in the product may not contain viable and appropriate no. of beneficial microbes . the strain in the product may not be compatible with the crop that is being inoculated (addition of microbes) . Their problem of in time availability and transportation under appropriate (suitable) conditions

Advantages and disadvantages of fertilizer?

Advantage: It provides much-needed nutrition to growing plants. Disadvantage: Depending on the composition, it may introduce unwanted chemicals into the soil.

What is an advantage of fertilizers?

That they help plants grow strong by making nutrients available in the most accessible forms and places is an advantage of fertilizers. Specifically, fertilizers give plants the nutrients that they need to grow strong fast. They help out when soils are poor. They see to it that plants have strong roots and properly sized and timed flowers and fruits.

What are the advantages and the disadvantages of fertilizers?

That they aid plant and soil health and that they encourage dependent growth and have side effects are examples of advantages and disadvantages of fertilizers. Specifically, fertilizers add necessary nutrients to poor soil. They aid in better soil structure whereby particles hold together but also provide pore space for air and water. But at the same time, fertilizers become crutches and have side effects, such as affecting the availability of other nutrients in the soil.

What chemicals are in fertilizers?

The principal elements in fertilizers are nitrogen, potassium,phosphorous; also microelements as calcium, sulfur, iron, copper,magnesium etc.

What do chemical fertilizers do to you?

They can harm you by getting the chemicals in the fertilizers into your body. The fertilizer does this by they chemicals in it get into the ground and if you have a well; they water still has a little bit of chemicals in it. If you don't have a well, you still might want to be careful. I'm not sure if this is right but I'm pretty sure this answer is a lot better than most people would put. My mom is doing a research project about chemical and organic fertilizers so I'm am learning a lot from her and she is learning a lot from me. HOPE THIS HELPS!!!

Advantages of inorganic fertilizers?

Primarily the reduction of the volume to be applied and the rapidity of availability to the crop. Chemical fertilizers have a much higher percentage of the nutrients per unit of material which saves the farmer both time and money in application.

What are advantages and disadvantages of phosphorus fertilizer?

Phosphorus is bad for the soil in that its overuse may lead to its leak into underground aquifers. The warning light turns red when phosphorus enters water, cos it results in growth of algae, which take up way too much oxygen.

What are the advantages of artificial fertilizer?

Artificial fertilizers that are applied excessively or at the wrong time can wash through soil into rivers, and eventually, the ocean. Excess nutrients cause algal blooms, and the algae use up all the oxygen, resulting in fish kills and ocean dead zones. Chemical fertilizers also simplify soil ecosystems. Earthworms move out to escape nitrate salt fertilizers, and chemicals inhibit the growth of beneficial fungi that supply nutrients to plants in natural soils, and attack or compete with bacteria and harmful fungi that infect plants. Many plant pathogens that are weak competitors in natural ecosystems thrive in the simplified ecosystem of chemically farmed soil.

What are the advantages of chemical fertilizers and pesticides?

Fast acting and results oriented are advantages of chemical fertilizers and pesticides. Specifically, chemical fertilizers act nutrients quickly into the soil and into the plant's roots and circulatory system. Immediate results are seen in the growth of roots and shoots and the development of flowers, fruits and seeds. The same instant gratification can be achieved when chemical pesticides are used. Chemical pesticides kill the pest in question.

What are the advantages of fertilizers and pesticides?

That they make necessary nutrients available to soils and roots and that they control pest problems are respective advantages of fertilizers and pesticides. Specifically, fertilizers contain nutrient ingredients that are critical to plant, soil and soil food web health. These nutrients exist in the soil, but sometimes in inaccessible forms or inadequate amounts. Fertilizers give plants the strength to survive pests that pesticides control or eliminate.

Advantages of internal over external fertilization in plants?

With internal fertilization, ovums are more protected so that seeds can be grown to maturity. The chances of seeds growing into daughter plants may also be a little higher than plants that use external fertilization, however the number of seeds produced by a plant that uses external fertilization over internal is much larger to increase the chance of more seedlings being produced.

What are the advantages of using natural fertilizers?

That they contribute to sustainability, encourage morebalanced growth, have healthier impacts on plants, soils, and soilfood webs, and support the mantra "Reduce, reuse, recycle" are advantages of natural fertilizers. Specifically, natural fertilizers do not involve chemical inputs,genetic modifications, or toxic ingredients. They often draw uponhumus as created by the human-intervened process of composting ofcarbon- and nitrogen-rich recyclable materials that otherwise wouldoverflow landfills. They thereby foster the sustainability ofhealthily and naturally attractive and productive landscapes. Theygive plants and soils the gamut of necessary nutrients withoutover-emphasizing the macro roles of nitrogen, phosphorus, andpotassium. They therefore have a greater role in environmentalwell-being by attending to plant growth that is not achieved to thedetriment of the life of the edible or ornamental in question or ofthe aeration, drainage, and fertility of the soil and the soil'sattendant food web of microscopic and visible organisms.

Why use of chemical fertilizers is harmful?

Use of chemical fertilizers is not very harmful and displays side-effects after long term use. Most of the common chemical fertilizers are useful and increase the productivity of soil but using them continuously decreases the natural fertility of the soil.

Is fertilizer a chemical?

No. There are many different kinds of fertilizer, so fertilizer does not have a definite chemical composition.

What are the advantages and disadvantages of inorganic fertilizers?

the advantages to inorganic fertilizers is that it makes the plant grow bigger and faster than organic. But the disadvantage is that it might kill the plant. Inorganic fertilizers have a lot more nitrogen so can boost the plants growth a lot. But part of that is in the form of ammonia, and if you've ever experienced ammonia, you will realize that if it builds up in the soil it will sterilize the soil, in which case there will be no way for organic fertilizers to get into the food chain of the plant, so you're then stuck with more inorganic fertilizer, and so on. Also, inorganic fertilizer can sometimes push the plant into too much growth at the wrong time, like folks who want a nice green lawn when the grass should be shutting itself down and preparing for either winter or the dry season, rather than putting out new leaves to get killed.

The advantages and disadvantages of bio fertilizers?

Bio-fertilizers are normally the name given to manure and compost, although there are other materials which qualify. Advantages . wider range of nutrients, particularly micronutrients . help increase soil organic matter content . relatively inexpensive . no (or negligible amounts) of harmful materials such as heavy metals Disadvantages . much lower nutrient density -- requires large amounts to get enough for most crops . requires a different type of machine to apply than chemical fertilizers . sometimes hard to locate in certain areas . odor

What are the advantages of homemade orchid fertilizers over commercial fertilizers?

That they can be adjusted to fit the individual situation is an advantage of homemade over commercial orchid fertilizers. Specifically, orchids are picky drinkers and eaters. Commercial orchid fertilizers benefit from the most current research on how the plant responds to different ways of meeting its needs. But each homegrown orchid situation can be unique to the plant caregiver. Homemade orchid fertilizers let the plant be fed in the way that the individual orchid owner sees as best from daily inspection.

What is the main advantage of using a warm solution over a cold solution in a chemical reaction?

When solutions are heated, molecules are excited and speed up. This increases the chance that they will "bump" into each other and react, thus increasing the reaction rate. Also, many reactions require a certain Activation energy in the form of heat to even start the reaction.

Why double fertilization is advantageous for plants?

because it produces on one side ovule n on the other hand it provides nutrional endospeerm

What are the advantages of vapor steam cleaners over chemical cleaners?

Vapor steam cleaners use fresh water to create steam which loosens dirt and allows you to clean without using harmful chemical and pollutants. This is especially important if you have children or pets.

What are the advantages and disadvantage of self fertilization?

The advantages of self fertilization are that it eliminates the need for a secondary donor and it eliminates the risk of contamination. The major disadvantage is that it severely limits the variation in genetic material.

Why do farmers prefer manure over chemical fertilizers?

they prefer it because people dont want potentially dangerous chemicals on their food and manure is a lot more natural :-p

What are chemical fertilizer?

Chemical fertilizer is any inorganic materials that is inserted into the soil for the growth and cultivation of plants. Examples are ammonia, ammonium sulphate, potash, urea, sodium nitrate, ammonium nitrate. The main role plays by the substance called nitrogen which are used in all these chemical fertilizers that helps to acidify the soil, very useful for the growth and stability of plants. I hope that will enough to clarify your point.

Why organic fertilizers are preferred to chemical fertilizers?

It is only a legend; natural fertilizers are not completefertilizers (they doesn't contain phosphorous, potassium, calcium,microelements), the quantities are not sufficient and they are alsoa great source of pollution.

What are advantages of organic fertilizers?

Organic fertilizers are composed of decayed and fully decomposedplant and animal material, including biodegradable food waste, deadplants and animal manure. Because it is not synthesized (created ina laboratory by mixing chemicals and elements), organic fertilizeris more quickly consumed by plants and will not leave traceminerals or chemicals in soil. Organic fertilizers do not createsoil chemical imbalances that may leak into water bodies and causeundue harm to animals, people and other plants.
