Abstract

The system integration crop-livestock-forest has the characteristic to integrate components both grassy culture among the herbivorous animals. The implementation of this system aims to be sustainable, seeking to exploit the maximum area, and reduce the impacts on soil properties. This work aims to study the physical attributes of a Oxisol in a crop-livestock-forest integration system since 2012, as well as the production of grass marandu. The experimental design is a randomized block with four replications and composed of four treatments: T1 - croplivestock integration, without the tree component; T2 - agrosylvopastoral system with shading 1 line of eucalyptus, with a density of 196 trees / ha; T3 - agrosylvopastoral system with shader 3 rows of eucalyptus, with a density of 448 trees / ha; and T4 exclusive planting of eucalyptus. The experiment will be evaluated in the June 2017 to may 2018, the soil classified as Oxisol. The assessments to be carried out will be the soil physical properties (water-stable aggregates, soil porosity, soil bulk density infiltration rate, penetrometer resistance, soil moisture) and forage production. Soil analysis will be made in three depths of soil, of 0-0.05; 0.050.10 and 0.10-0.20 m. The results will be analyzed and we performed analysis of variance, correlation simple at 5% probability for the comparison of means. (AU)
