- Abstract
With the objective of evaluating of nutrient availability; its structure and water-air relationship under different management in inceptisol soil. The present work was carried out in the Experimental Agricultural Station "Alvaro Barba Machado". Three samplings were carried out in 2004, 2006 and 2007. They took four areas: two were planted with Leucaena leucocephala established 2 and 3 years old; one with natural grass and another with permanent crop. In all areas it were carried out chemical and physical analysis of soil, to depth of 0-10cm, 10-20cm and 20-40cm and an experiment under controlled conditions was developed, using corn as indicative plant. For statistical analysis was used the software STATGRAPHICS Plus 4.1 and SPSS ver. 8 on Windows 2000. The use of the tree Leucaena leucocephala cv Perú in an agricultural system increases the active layer of soil, this was expressed in the improvement of the soil states until 40cm of depth, such as matter organic, stable aggregate, structure factor and phosphor assumable.
