Abstract
The study and knowledge of soil properties for improvement and protection is essential. Leachate Red Ferrallitic soils that have been subjected to intensive cultivation at present symptoms of degradation, however, with proper management of them can recover their productivity. The work aims to obtain management practices leading organic presenting amendments to the benefit of these soils. Soil samples were taken and their characterization. They divided the area selected for the experiment on three parcels of about 60 rows each and evaluated the following treatments (control (plot I), 1 t/ha (plot II) and 2 t/ ha (plot III) organic fertilizer ) and the indicator crop was corn (Zea mays L), agricultural tasks recommended for cultivation. The initial characterization results demonstrate that there are changes in the properties of these soils, mainly low organic matter content, as reflected in the high density compaction a plow near surface low causing water infiltration; high scattering coefficient and low structural stability. However, with the applications of organic matter from cattle dung 2t/ha improved the characteristics of these soils and there was a trend to increased crop yields in corn, through the indicators evaluated, over the ears, Ø ear diameter, grain number of rows, number of kernels in the row, weight of ears and weight of 100granos. The best variant was the plot III, followed in descending order plot II and compared with the control, the results were remarkably low.
