The preservation of the soils in farms with Theobroma cacao, L. in Baracoa municipality.

Abstract

The research has been carried out at a UBPC in Baracoa municipality with the objective of evaluating different measures of soil conservation and improvement in cocoa agroecosystems. The behavior of the erosive processes was diagnosed throughout the determination of soil losses at 10 and 20 months, and the soil and climatic characteristics of the region. In order to determine the soil losses, a six percent of slopes (12, 16, 29, 35, 38 and 45) were studied, which constitute the treatments assembled in a randomized block design with three retorts. The results of the diagnosis have allowed the selection and application of conservation alternatives and improvement of its properties while demonstrating the highest losses of soils at higher slopes and under heavy rain conditions. The conservation alternatives applied have had a positive impact on some indicators of the physical, chemical and biological quality of soils.
