What is conservation tillage?
Tillage refers to turning the soil over to prepare it for planting crops or to control weeds. Conservation tillage minimizes the disruption of soil by using specialized equipment that enables the seed to be planted directly into standing stubble.
It can take 100 to more than 500 years to form 2 cm of topsoil! Conservation tillage helps rebuild topsoil by slowing adding organic matter from the previous year’s crop.
The Dirty Thirties
In the 1930’s, a combination of drought and frequent tillage caused a major farming crisis on the Prairies. High winds and lack of rain caused the topsoil to blow away, turning the sky dark with dusk, while devastating farmers crops.
