Impact of Agrochemicals on Soil Biota and Ways to Mitigate it: A Review

Agricultural production is largely based on the use of agrochemicals in order to minimize pests, pathogens, and undesirable weeds toward increase production. In the current situation, however, several threats are emerging that threaten food security, human and environmental health, ecological balance, and soil biodiversity. Agrochemicals may shift beneficial microorganisms in the community over time, with potentially dangerous consequences, such as the development of antibiotic resistance. Farming systems utilizing agrochemicals might adversely affect soil microorganisms responsible for nutrient cycling processes, such as: nitrogen fixation, phosphorus solubilizing, and others. Some agrochemicals reduce soil enzyme activity and biochemical reactions, which are key indicators of soil microbiology. In this review, we explore how applied agrochemicals affect soil microbes and biochemical health attributes under different cropping systems, as well as ways to overcome the negative impacts of agrochemicals.
