 Author(s): DINIZ, A. R.; GUARESCHI, R. F.; PEREIRA, M. G.; FERNANDES, D. A. C.; BALIEIRO, F. de C.; SILVA, E. V. da; PICCOLO, M. de C. This study quantify the total organic carbon content, light fraction organic matter (LFOM), and soil organic matter fractions (from chemical and physical fractionations) in four different cultivation... ... |
 Author(s): OLIVEIRA, G. F. de; MAFRA, A. L.; CORREA, J. C.; HENTZ, P.; CECHETTO, M.; ROTERS, D. F.; PRAZERES, M. S.; ANDOGNINI, J. Abstract: The use of organic fertilizers from pig slurry and poultry litter can increase soil organic carbon and crop productivity. This study aimed to evaluate soil organic carbon fractions and corn... ... |
 Author(s): SOUZA, G. P. de; FIGUEIREDO, C. C. de; SOUSA, D. M. G. de ABSTRACT: The study of labile carbon fractions (LCF) provides an understanding of the behavior of soil organic matter (SOM) under different soil management systems and cover crops. The aim of this stu... ... |
 Author(s): MARQUES, J. D. de O.; LUIZÃO, F. J.; TEIXEIRA, W. G.; NOGUEIRA, E. M.; FEARNSIDE, P. M.; SARRAZIN, M. Transformations of natural ecosystems in tropical regions, which are usually covered by high-biomass forests, contribute to increased atmospheric CO2. Much of the carbon in forest ecosystems is stored... ... |
 Author(s): MATOS, E. da S.; CONCEIÇÃO, M. C. G. da; BIDONE, E. G.; RODRIGUES, R. de A. R.; CORDEIRO, R. C. Integrated crop-livestock-forest (ICLF) systems has been considered as an important strategy to enhance C sequestration. However, changes in soil C due to agricultural management practices, in general... ... |
 Author(s): SOARES, D. de A.; SEKIYA, B. M. S.; MODESTO, V. C.; NAKAO, A. H.; FREITAS, L. A.; SOUZA, I. M. D. de; LUZ, J. H. S. da; GALINDO, F. S.; LUPATINI, G. C.; MATEUS, G. P.; BONINI, C. dos S. B.; ANDRIGHETTO, C.; MENDES, I. de C.; PAVINATO, P. S.; ANDREOTTI, M. Food production in sandy soils has evolved significantly, most notably through the advent of integrated crop–livestock systems (ICLSs). ICLSs increase soil cover, which maintains soil moisture and seq... ... |
 Author(s): MADARI, B. E.; LIMA, L. B.; SILVA, M. A. S.; NOVOTNY, E. H.; ALCANTARA, F. A. de; CARVALHO, M. T. M.; PETTER, F. A. Biochar incorporation into the soil is a proposed C sequestration strategy. How newly applied biochar affects C accumulation in the soil is therefore a relevant question. This study presents part of t... ... |
 Author(s): NASCENTE, A. S.; LI, Y.; CRUSCIOL, C. A. The objectives of this study were to elucidate the effects of crop rotation with cover crop species in the soil aggregation, total organic carbon concentration in the whole soil and in the soil aggreg... ... |
 Author(s): CEDDIA, M. B.; GOMES, A. S.; VASQUES, G. M.; PINHEIRO, E. F. M. Soils from the remote areas of the Amazon Rainforest in Brazil are poorly mapped due to the presence of dense forest and lack of access routes. The use of covariates derived from multispectral and rad... ... |
 Author(s): SILVA, J. R.; SILVA, D. J.; GAVA, C. A. T.; OLIVEIRA, T. C. T. de; FREITAS, M. do S. C. de Soil organic matter (SOM) plays a key role in maintaining the productivity of tropical soils, providing energy and substrate for the biological activity and modifying the physical and chemical charact... ... |
