Why do farmers use chemicals?
Chemical fertilizers and herbicides cost money. Spraying the edge of a field where the crops are not growing would be a waste of resources. In the case of fertilizers, spraying the edge of the field would benefit only the growth of natural weeds and hedgerows.
Is the use of man made fertilizers and pesticides a good thing for agriculture?
No, the use of man made fertlizers and pesticides are not a good thing for agriculture
How do pesticides and fertilizers relate to water conservation?
It depends upon the fertilizer and the pesticide. But generally artificial, commercial, conventional, synthetic fertilizers and pesticides don't cooperate with water conservation strategies. For neither improves soil drainage, fertility and structure. Both may alter the balance of nutrients within the soil. Specifically, repeated applications of such fertilizers need to be followed by additional watering, in order for the nutrients to be in the soluble forms that plant roots need for intake. And, specifically, the use of such pesticides may affect beneficial insects such as ground beetles. Ground beetles improve soil health by opening up air and water pore spaces, and by feeding on the soil food web. What they digest, and then eliminate, becomes available for soil and plant use. Their absence therefore is to the detriment of plant health, soil health, and water conservation strategies. The concomitant problems of soil compaction, erosion and saturation aren't addressed. Therefore, rain and snow fall events tend to wash away controls, and nutrients, along with soil. And thus starts up another vicious cycle of fertilizer and pesticide applications, and ever more frequent watering schedules.
Why do farmers use artificial fertilizers?
So that their crops grow better. But, some fertilizers make it harder for microorganisms in the soil to produce nutrients naturally.
Compare the use of manure and fertilizers in maintaining soil fertility?
Manures contains many organic substances of biological origin which can be easily degraded and absorbed by plants.Its helps in recycling of biological waste they increase soil fertility of the soil for long duration without causing any harm.The chemical fertilizers on other hand,improve soil fertility for short duration but cause environmental hazards.Continose use of fertilizers in particular area causes destruction of the soil fertility.
What detrimental effect can the long-term use of pesticides and fertilizers have on soils?
The long-term use of pesticides and fertilizer can leave chemicals in the soil which can have toxic effects on certain crops and can contaminate agricultural workers, livestock and nearby strams.
What fertilizers do a gardener use?
soil
Which soil requires least use of fertilizers?
alluvial soil
How many bees are getting killed by fertilizers?
Fertilizers are not so much of a problem. The biggest problem is the use of pesticides on crops.
Are the use of pesticides and fertilizers damaging?
The use of fertilizers and pesticides can be harmful to the environment, and to the farmer or gardener using them. Usually, there are not enough toxins in the substance used to harm the consumer of a crop.When it rains, fertilizers will be carries through streams and eventually into rivers. Fertilizers can causse an over-growth of alage and cause eutrophication. Fertilizers also can increase the health of certain pests, such as insects or mice.Human exposure to pesticides can cause...increased risk of leukemiacancers (lung, brain, testicular, lymphoma)increase in spontaneous abortionsgreater genetic damagedecreased fertilityliver and pancreatic damageneuropathydisturbances to immune systems (asthma/ allergies)increases in stillbirthsdecreased sperm counts
Why are organic food more healthy?
People believe organic foods are healthier because they are grown without the use of synthetic fertilizers, pesticides, and herbicides, there are more nutrients available in the soil due to the use of compost and other soil-builders, they are GMO-free, etc.
How do fertilizers affect resources?
the affect of fertilizers on the resources is that our farmers use fertilizers in order to maintain the fertility of soil except organic fertilizers
Indiscriminate use of fertilizers and peticides?
Stop the use of pesticides because it is not good for the environment. But don't stop using fertilizers because they are good for the environment or at least some of them are!
How is the use of fertilizers and pesticides harmful for fruits and vegetables?
That they can emphasize one type of growth over another, that they do not always treat the underlying stress, that they interrupt Mother Nature's work, and that they may have detrimental after- and side-effects are ways in which the use of fertilizers and pesticides arm harmful for fruits and vegetables.Specifically, fertilizers are designed to emphasize above-ground growth, which must be balanced by proper below-ground development of roots. A plant actually "feeds" by what the roots intake. Inadequately or improperly developed roots will not eliminate wastes or intake life-sustaining, soluble minerals, nutrients and trace elements.The underlying stress often can be a problem with site conditions. For example, the soil may be lacking in the minor elements which Justus Freiherr von Liebig (12 May 1803 - 18 April 1873) proved to be as critical as major elements in their absence. Many fertilizers will be top-heavy in delivering major elements, for which they are named "NPK" -- nitrogen, phosphorus, potassium -- soil-amenders.Fertilizers and pesticides constitute human intervention in Mother Nature's own processes. They need to be part of an integrated management program that considers soil, soil food web, and plant well-being. Otherwise, fertilizers and pesticides tend to emphasize lush production for big profit margins over healthy growth in sustainable landscapes.Fertilizers and pesticides can have effects beyond their intended targets. They may leave toxic residue in the environment. The immediate problem of getting a plant to grow bigger and faster may be solved, at the cost of area people, plants and wildlife.
Who founded organic food?
No one founded organic food. Growing food organically, without the use of synthetic fertilizers and pesticides, was the way food was grown before chemical fertilizers and pesticides were created, patented, and marketed.
How nutrients can be replenished in the soil without the use of fertilizers?
by manure.
How is the Green Revolution associated with loss of soil fertility?
The Green Revolution refers to the technology initiatives taken from the 1940s-1970s to increase efficiency of agricultural production. These initiatives include the use of pesticides, fertilizers, irrigation, and high yield varieties of seeds (HYVs). But the Green Revolution also has also caused a decrease in soil fertility and biodiversity because of the pesticides and excess use of fertilizers. In Pubjab, the land has degraded since the the Green Revolution. With multiple crop rotations in a single year and heavy chemical fertilizers, the land has lost its carbon material, and it not as fertile as before, despite an increase in production.
