Resumo: | Organic carbon is a major component of soil organic matter and its stock is influenced by the management system adopted. This study aimed to examine the effects of cropping systems and nutrient sources (mineral and organic) on the concentrations and storage of soil organic carbon in no-tillage system. The experiment was carried out in Mercedes, Parana, Brazil, in an Nitossolo Vermelho (Alfisol) from October 2007 to September 2009. The treatments consisted of four crop succession systems: (1) soybean/wheat/corn/wheat; (2) soybean/black oat/corn/black oat, (3) soybean/radish/corn/radish and (4) soybean/common vetch/corn/common vetch and by two sources of nutrients (mineral and organic), arranged in a to split plot randomized block design with four replications. Soil samples were collected in layers of 0.0-0.05, 0.05-0.10, 0.10-0.20 and 0.20 to 0.40 m deep in the first and the second years of cultivation. Different cropping systems does not affect the content and the stock of soil organic carbon in the first two years of adoption of the systems. The organic fertilization with manure increased soil organic carbon stock, with an annual contribution of C, layer 0.0 to 0.20 m, 1.15 Mg ha(-1) yr(-1). Cropping systems fertilized with mineral fertilizers provide the greatest losses of soil organic carbon, resulting in negative balance of C in soil. |
