After harvesting stubbles of maize or soy remain on site. When the planting season started the soil is opened by rolling discs pulled by a tractor. The seeds are directly put into the open soil which is compacted afterwards with rolling wheels of the same machine.
Purpose of the Technology: With minimum tillage practices tilling and seeding operations could be implemented fast and very efficient. The high power of impact allows the cultivation of large fields in short time, especially if small windows of wet initial conditions need to be used. The purpose is to avoid deep plowing of the soils that would need much higher energy and costs and would lead to typical serious erosion problems in the tropics.
Establishment / maintenance activities and inputs: The technology was implemented in the area since approximately 15 years. High technological standard of tillage tools, tractors and service is needed. Since the whole farm system has changed, farmer need special knowledge in no-till measures especially with regard to pest management.
Natural / human environment: The region belongs to the semi-humid tropics and to the cerrado biome in the centre of the South American continent. Natural vegetation has been deforested some 20-40 year ago and was shifted to soy bean fields, pastures, corn and sugar cane fields.
