THE CONSERVATION GAME
Secretary for Conservation Agriculture in the Western Cape, Dr Johann Strauss, explains why SA needs the no-till intervention: “Nearly 80 per cent of Western Cape farmers having a no-till machine. Jack Human was the first to start after he lost land to a flood in 1983.
South Africa is a water-scarce country and there’s limited soil for agricultural production. The use of no-till helps lower the loss of carbon and moisture from the soil. For every one per cent of added carbon to the soil, the water-holding capacity of that soil doubles. Mulch not only reduces soil erosion, it reduces soil temperature by at least 4° C, creating better conditions for these organisms to thrive.
Conservation agriculture, which includes no-till, will be the only way we’ll feed humanity in the future.”
