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
Disadvantages of using chemical fertilizers would be that they seep into the ground. This can pollute groundwater and can runoff into rivers and streams.
The advantages of natural fertilizers would be that they are not made of chemicals and not harmful for the body. A disadvantage is that they smell bad and don't work as well.
Contamination of soils, waters and products.
Advantages: Paid Well Disadvantages: Hard Work
Nothing because natural products are the best.

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.

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.
The advantages would be that chemical energy doesn't pollute, and it stores many things. The disadvantages would be pollution caused by the burning of fuel cells.
The difference is that chemical fertilizers have chemicals. And bio fertilizers don't.
What are some disadvantages or advantages in chemical energy?
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.
Advantages-immediate eradication of problem. Disadvantages- It is poison. You must follow all label directions to the letter.
As opposed to what kind of reaction?

Bio-fertilizers are normally the name given to manure and compost, although there are other materials which qualify.Advantageswider range of nutrients, particularly micronutrientshelp increase soil organic matter contentrelatively inexpensiveno (or negligible amounts) of harmful materials such as heavy metalsDisadvantagesmuch lower nutrient density -- requires large amounts to get enough for most cropsrequires a different type of machine to apply than chemical fertilizerssometimes hard to locate in certain areasodor
Availability, costs and results may be disadvantages of using natural fertilizers. Artificial, chemical, inorganic, synthetic fertilizers are available through a widespread, established network of suppliers. Also, prices tend to be higher, and amounts tend to be smaller, in terms of natural fertilizers. Additionally, natural fertilizers tend to produce less dramatic results over a longer period of time.
In the short term, chemical fertilizers offer a greater crop yield, which supports a higher population. When the fossil fuels diminish, the farm land will not sustain the same population.Contamination of soils, waters and products.
Biofertilizers are for environmentalists. Chemical fertilizers get the job done faster, better and with more interesting reactions. Hint: Look at the base of the flower root three minutes after applying any chemical fertilizer, and watch it change colour.
Actinium (the chemical element) is not used in agriculture.
Advantage of chemical food preservation
The use of chemical fertilizers is harmful only if they are used unreasonable.
