AbstractThe soils of the area of Bella Union are deep, of high inherent fertility, and can hold and supply sufficient amounts of water to a growing crop. They are mostly sandy clay loams and clay loams. Soil pH varies between 5.2 and 6.4. Some 38% of the soils have drainage problems mostly because of underlying impervious layers dominated by montmorillonitic clays. Irrigation and drainage are essential to guarantee high levels of crop production. Erosion can be a problem in some of the soils if they are not adequately protected. The use of open drains of suitable depth and spacing will help to maintain an optimum environment for the crops and, if well designed, can also help to minimize soil erosion.
