Pesticides (Herbicides, Insecticides, Miticides, Fungicides etc.) may affect soil microbes in many ways, often leading to reduced diversity and even lower populations of various soil microbes. Soil microbes are bacteria, fungi, archaea, protists, and viruses and account for an estimated 3%–4% of the total biomass on earth. Pesticides often degrade soil health and can lead to lower agricultural productivity or lower crop yields. Some pesticides change the soil structure so that soils become dense and compacted. Minimizing pesticide use is beneficial for improving soil health and microbial diversity and increasing soil microbial populations. Broad-spectrum herbicides are those that kill or control a wide variety of pests including weeds, fungi, and insects. Since they are so non-selective, they can kill or control beneficial microbes as well as both targeted and non-targeted organisms. Often broad-spectrum pesticides may also harm pollinators and beneficial predators. When this happens, ...
