Conteúdo: |
Oxisols and Ultisol are the predominant soils in the nontraditional warm areas where wheat is grown in Latin America. They are clayey soils where kaolinite, iron, and aluminum oxides are the most important minerals in the clay fraction. Cation exchange capacity is generally low and organic matter content is less than 3.5%. When soil moisture is high, these soils have a plastic and sticky consistency. The most important crop production system is a winter crop of wheat followed by soybeans in the summer. Small areas are sown to maize and cotton as an alternative to soybeans. At least four soil tillage systems are common in the areas under discussion: traditional, conventional, chisel, and no-tillage--in addition, there can be various combinations of these. Dueto the fragile tropical ecosystem, these soils can be physically degradated when inappropriate soil tillage and management systems are used. The most common problems observed are the pulverization of the topsoil structure, a hard pan below the plow layer, and soil erosion. Tillage systems involving burning of crop residues and disk machinery are particularly responsible for such problems. Soil tillage systems have various degrees of efficiency and the choice of a specific system, associated with reduced machinery use and the improvement of crop rotation systems, appears to stop or even reverse the process of physical soil degradation. |
