Resultados de algunas investigaciones en suelos Vérticos de Cuba.

In Cuba, the major quantity of areas affected by waterlogging and salinity are occupied with vertisols, this soils cover around 30 % of the potential cultivated areas in the country. The particular feature of this soil to contract and swelling with the variations in soil water content, due to the particular type of clay they content (smectites), pose a great constraint for is agriculture use without irrigation as well as under irrigation. The managing of vertisols following methods and techniques used in non-dilatable soils may conduce to a rapid soil degradation and a failures in agriculture production. Taking into account the research work carry out for different Cuban's research institution in the 80´s, this paper expose some of the most important results and emphasize in the vertisols water related properties' in order to obtain the best result when this typical soils properties' are taking into account in vertisol management.
