FYI: We try to leave jargon out of our videos, but if you want to learn more about this topic, here are some handy keywords to get your googling started:
Agricultural Soil Erosion: the wearing away of a field’s topsoil by the natural physical forces of water and wind or through forces associated with farming activities, such as tillage.
Conservation tillage/agriculture: a soil cultivation method in which fields are not ploughed & the previous year’s crop residues are left on fields before and after planting the next crop, to reduce soil erosion and runoff.
Soil: the upper layer of earth, in which plants grow; a dark, damp, gas-filled structure of minerals and organic matter formed by degrading rocks and decomposing organisms.
