What is conservation tillage?
Planting without ploughing, a revolutionary cultivation technique in which the fields are not ploughed. "This concept sprang directly from the recognition that mechanical ploughing is contributing to land degradation on a massive scale.
Using conservation tillage, farmers leave crop residues on their fields after harvest, instead of ploughing them in or burning them off. They plant new crops with specially designed planters. These guide the seeds down into a slot in the soil underneath the protective layer of mulch formed by rotting residues.
