Abstract

During the last 20 years the science of soil has worked on the soil degradation. The Red Ferralitic Soils of “Lázaro Peña” enterprise are not excluded of this process as they are extremely subjected to an intensive cultivation, which causes alterations of its chemical and physical - chemical properties. The diagnostic of these processes allows to design strategies for its recovery, so that this work has the objective to characterize since the physical and chemical points of view the soils of this enterprise. For this reason samples of soils of each Basic Units of Cooperative Production of the enterprise were taken and the correspondent analisys at Research Tobacco Institute were carried out. The results showed high value of pH on the soils which constitutes a limit for tobacco production due to the requirements of tobacco plant. Besides the content of organic matter are low in spite of proving an increase which improves the levels of soil fertility. An unfavourable calcium / magnesium and relationship is shown as a a result of an intensive tobacco cultivation because the irrigation is carried out with hard water which limits besides limits the absorption of magnesium due to they are antagonistic elements. The phosphorus and potassium values are suitable for these soils. As conclusion, there is a high Ca/Mg relationship and reaction of the soil , that suggests to search of new alternatives for improvement and conservation of the soils.
