Rediseño de finca para contribuir con la fertilidad del suelo Ferralítico Amarillento Lixiviado

A redesign of an agricultural agroecosystem with an extension of 2.0 ha, in the property «Aldalina» of «Estelo Diaz» Credits and Services Cooperative, was undertaken to contribute in the improvement of soil fertility in Pinar del Rio province, Cuba, located in an altitude of 28 meters above sea level, 291, 290 North coordinates and 233, 210 to the East of the southern plain of the province. The economic, technical - productive, social dimensions were evaluated, so as the food security attributes (performance, economic risk, soil quality, crop health, land tenure and social networks) based on an agro-ecological methodology for the characterization and classification of the systems, on a scale of 1 to 4; (1 Very low; 2 under; 3 medium; and 4 high). An evaluation of food security of the production of the study area with an average value is done, showing high economic risk, low yields of crops, poor soil quality, low pH and organic matter, high involvement by pests, and weeds do not compete with crops in critical moments. The redesign consist on the use of cover crops from plots associations with a vertical and horizontal spatial distribution, to capture sunlight. The Soil is in a degradation process, management in this natural resource is inadequate and there is little diversity of plants in the agricultural ecosystem.
