Morning class, I brought you out here to learn all about soil
Farmers alternate the types of crops from year to year, does anyone know why they do this?
It Renews the soil and helps prevent pests and diseases
Also it prevents soil erosion
Soil is not tilled from year to year. The previous crops standing protects the soil.
Tillage erosion is the turning over of soil. This loosens and lightens the soil. It also creates pores for water and air movement
It also contributes organic matter to the soil.
This also helps warm up the soil quickly to speed decomposition of organic matter
