Pesticides and pollution of the soil First, affect soil quality. Decrease biodiversity in the soil because they do not just kill the intended pest; they often kill many of the other small organisms present. Soil quality deteriorates and this has a knock-on effect upon the retention of water. Soil fertility is affected too. When pesticides kill off most of the active soil organisms, the complex interactions which result in good fertility break down. Plants depend on millions of bacteria and fungi to bring
Biological factors. Plants, animals, micro-organisms, and humans affect soil formation. Animals and micro-organisms mix soils and form burrows and pores. Plant roots open channels in the soils. Different types of roots have different effects on soils.Grass roots are âfibrousâ near the soil surface and easily decompose, adding organic matter.Taproots open pathways through dense layers.lant roots open channels in the soils.
