Abstract
RODRIGUEZ DELGADO, Irán; PEREZ IGLESIAS, Hipólito Israel; GARCIA BATISTA, Rigoberto Miguel and QUEZADA MOSQUERA, Arturo Joel. Effect of agricultural management on physical and chemical soil properties in different agroecosystems. Universidad y Sociedad [online]. 2020, vol.12, n.5, pp. 389-398. Epub Oct 02, 2020.

The research was developed with the objective of evidencing the influence of the agricultural management system on physical and chemical properties of the soil at two depths (0-15 and 15-30 cm) in agroecosystems of the Santa Inés farm. Banana, short cycle, grass, cocoa and forest crops were selected, where permanent sampling points were randomly established, and three calicates were carried out. Soil samples were taken at each depth, homogenized to ensure representative sampling. In order to know whether or not there are significant statistical differences between the means of the physical and chemical properties of the soil as a function of the production systems, the inter-group factor ANOVA (α=0.05) and multiple range tests were used to establish between which system differences or similarities are found. In cocoa and forest, the highest MO off soil values were achieved, attributed to the large number of leaves, branches and stems generated, which are incorporated into the soil by the activity of microorganisms. It was shown that continuous and intensive exploitation of the soil causes a decrease in carbon sequestration and increased compaction, as well as low incorporation of organic waste and low fertility.
