As part of a major effort to improve quality of native savanna soils for agricultural production in the Llanos of Colombia, a field experiment was established in May 1996 to determine the impact of vertical tillage, application of soil amendents and fertilizers, crop rotation and crop-pasture rotations on the buildup of an arable layer. The experiment tested two methods (1) vertical tillage using chisel and( 2) vertical tillage plus use of adapted crop and forage germplasm associations. The results are included in this book.
