An agrochemical is any substance that humans use to help in the management of an agricultural ecosystem.
Agrochemicals include fertilizers, liming and acidifying agents (which are designed to change the pH), soil conditioners, pesticides,
and chemicals used in the raising of livestock such as antibiotics and hormones. The use of agrochemicals is an increasingly prominent
aspect of modern agriculture. As farms have become massive in size, the challenges in keeping the crop free of damage have increased.
Hand-tilling weeds has become impractical, as one example. Thus, agrochemicals have become widely used.
The use of agrochemicals has been critically important in increasing the yield of agricultural crops. However, some uses of agrochemicals
cause environmental and ecological damage, which detracts significantly from the benefits gained by the use of these materials.
