Abstract

In a no-tillage system, the absence of soil mobilization consequently decreases plant residue accumulation and places fertilizers on the surface, affecting the acidification process. Thus, application of inputs is necessary, especially materials for correction of soil acidity. Improvements in physical, chemical and biological soil conditions occur from lime application, which favors the production of biomass, increasing the quantity and quality of soil organic matter. The study will be developed at the Lageado Experimental Farm (Botucatu, SP, Brazil), continuing a research project that has been conducted since the 2002/03 crop year, in order to evaluate the effect of surface application of lime on soil organic matter pools. A randomized block experimental design with four replications will be used. Plots will consist of: control (without application of lime or gypsum), lime (2,000 kg ha-1 of lime without application of gypsum), gypsum (2,100 kg ha-1 of gypsum without application of lime) and lime+gypsum (2,000 kg ha-1 of lime and 2,100 kg ha-1 of gypsum), applied in October 2010. Soil organic matter fractionation will be carried out at 24 months after liming. (AU)
