Métodos y modos de desecamiento de terrenos húmedos por excesivas precipitaciones y acumulación de agua

Abstract

Watering is of utmost importance in agriculture, as well as drainage activity. Drying should be understood as the fundamental way, by which excess water is evacuated from a soil outside the territory in drying. In the practice of drying, two terms, methods or modes have been firmly established. The choice of them in each particular case is determined by the excess moisture of the land, which is given by the litology structure of the soil and by the nature of the subsequent use of the dried land. The measures of agro-improvement indicated form in the arable layer a primary drain (elementary) that accelerates the drainage. The purpose of this review is to compile in a coherent manner what is related to the methods or modes of drying of agricultural soils that by excesses of precipitation and accumulation of water the preparation and conditioning actions of the same are difficult for the food production. In conclusion, drying is a valuable method to reduce or eliminate water that is in excess in the soil and that affects the proper development of crops; if this important activity is not done, it results in a significant impact on the productivity of agricultural crops. In the drying practice in different periods of the year, they require a complementary wetting. At such times the excess water accumulated in the lower layers of the soil considerably dampens the damaging effect of the drought and becomes sources of complementary water supplies for the plants.
