Abstract

The organic carbon (CO) introduced in the soils, mostly via organic matter, plays a relevant role in several soil properties and outstanding importance in sandy soils. In these soils, the input of organic material is necessary to guarantee the sustainability of the production systems. The objective of this work was to verify the changes in CO contents, their influence on soil physical, biological and chemical attributes, in areas of commercial eucalyptus plantation, in the East of Mato Grosso do Sul. Soil samples will be collected at depths of 0.0-0.05, 0.05-0.10, 0.10-0.30, and for CO the depths of 0.30 to 0.50 m and 0.50 at 1.00 m will also be sampled. Fertility analyzes (P, MO, pH, K, Ca, Mg, H + Al, Al, S, B, Cu, Fe, N, Mn and Zn), total OC, carbon stock calculation, determinations of aggregates stability, density, macro and microporosity, total porosity, soil infiltration rate, accumulated infiltration, soil mechanical resistance to penetration, microbial biomass carbon, basal respiration (C-CO2), metabolic and microbial quotient, and enzymatic analyzes (²-glycosity, urease and protease) , will be performed to understand the influences of cultivation and treatments on the sustainability of sandy soils.
