Water Saving for Rainfed Crop Production in the Tropics through Surface Soil Conditioningn of the rainfall, with frequent and erratic dry spells of several days, and even weeks, in between. The resultant irregular soil moisture regime is the main cause of the very erratic and deficient agricultural production based on seasonal rainfed crops in the tropics (Pla, 1988).
