In Rio Grande do Sul and southern Parana, Brazil, researchers and farmers are firm believers in conservation tillage and winter cover crops. They credit conservation techniques with stabilization of soils in hilly to mountainous terrain. This benefits both farm and urban communities with reclaimed land, 30 percent increase in yield, clean water, and stable roads that had previously washed away with the rain. A group of U.S. scientists attended an international reduced tillage conference there and visited several research centers and farms to get a first hand look at the conservation successes in southern Brazil. Winter rain on bare fields caused the erosion and polluted streams. Cover crops reduced erosion. Conservation tillage increased cover crop effectiveness by decreasing the amount of time fields were without cover. Terraces, essentially berms every fifty feet on the contour, reduced slope length and held water for infiltration. Farmers in northern Parana had similar problems. The same conservation techniques did not work there because of different soil types and different crops like sugar and coffee requiring intensive management. Farmers in northern Parana continue to give conservation tillage a chance, but with caution and with some clean tillage. Information gathered by visiting researchers can help them assess conservation tillage in the U.S. and adapt it to marginal areas. |
