Agrochemicals are kinds of substances that are used in managing the agricultural ecosystem. Agrochemicals can be broadly sub-categorized as follows:

(A) Fertilizers – Fertilizers are used to enhance and alleviate the nutrient deficiencies in the land. The use of fertilizers hence ascertains the increase in the rate of crop. The most commonly used compounds in fertilizers are nitrogen, phosphorous and potassium.
(B) Liming and Acidifying Agents – This product is added to the soil in order to adjust the pH level of the soil to its optimum range. By adding this type of substance both acidic and alkaline soils are neutralized. In the case of acidic soils, primarily calcite is added, whereas, for the alkaline soils, however rare in occurrence, is neutralized by adding sulfur compounds.
(C) Soil Conditioners – This type of substance is added to improve the soil condition by means of enhancing the aeration and water holding capacity. Peat, crop residues, livestock manures are the common materials that are used in the production of soil conditioner.
(D) Pesticides – As its name suggests, this product is used to reduce the profusion of pests.
(E) Chemicals used in animal husbandry such as antibiotics and hormones

The beneficial side of the use of agrochemicals is of course the increase and enhancement of agricultural produces. On the other hand, it may also become a threat to ecological and environmental system.
