Agrochemicals help increase crop productivity. These agrochemicals can be insecticides, herbicides, fungicides, fertilizers, pesticides, and animal husbandry chemicals, among many others. Implementation of agrochemicals helps to manage plant nutrition, plant diseases, and crop yields. However, these agrochemicals have had a detrimental effect on biodiversity. This effect was because the application of pesticides had an effect not only on the growing population of pests but also brought about a decrease in the populations of non-pest insects. 

It hurts the microbes that live in the soil. These microbes are important for ecosystem functions like plant succession and soil formation.

The application of agrochemicals also causes damage to the soil structure. Soil structure disruption is actually a common phenomenon while using chemical fertilizers. The fertilizers infiltrate the subsoil, which reacts with the other components in the soil. As a result, it turns into a hard pan. These processes are a hurdle to the downward movement of the water and root growth. Another deleterious effect of fertilizer on the soil is soil friability. This happens because fertilizers stop soil crumbs from coming together. They are formed from humus, soil particles, along with organic matter. In turn, soil that is easy to break up makes it hard for water to drain and air to get to the roots of plants. Additionally, many chemicals that are used in agriculture affect the growth of mycelium and microbes.
