Management impacts on soil organic matter of tropical soils. Author(s): CASTRO, G. S. A.; CRUSCIOL, C. A. C.; CALONEGO, J. C.; ROSOLEM, C. A. Increased soil organic matter (SOM) improves the cation exchange capacity of tropical weathered soils, and liming is required to achieve high yields in these soils. Despite a decrease in SOM in the sh... ... Repository: BDPA Publication year: 2015
Cover crops affect on soil organic matter fractions under no till system. Author(s): ENSINAS, S. C.; SERRA, A. P.; MARCHETTI, M. E.; SILVA, E. F. da; PRADO, E. A. F. do; LOURENTE, E. R. P.; ALTOMAR, P. H.; POTRICH, D. C.; MARTINEZ, M. A.; CONRAD, V. do A.; JESUS, M. V.; EL KADRI, T. C. The purpose of this research was to identify the soil organic matter (SOM) fractions changes in a crop rotation system under no-till system (NTS). This research was carried out from October 2010 to Fe... ... Repository: BDPA Publication year: 2016
Soil and plant responses to pyrogenic organic matter: carbon stability and symbiotic patterns. Author(s): SAGRILO, E. Soil amendment with pyrogenic organic matter (PyOM) can sequester carbon, increase mutualistic root symbioses with arbuscular mycorrhizal fungi and nitrogen-fixing rhizobia, and hence improve crop yie... ... Repository: BDPA Publication year: 2014
The role of soil organic matter in sustainable crop production in the Tropics. Author(s): FAGERIA, N. K.; FERREIRA, E. P. B.; KNUPP, A. M. Soil organic matter has long been recognized as important indicator of soil productivity. Repository: BDPA Publication year: 2011
Soil organic matter quality in Jatropha spp. plantations in different edaphoclimatic conditions. Author(s): FREITAS, R. C. A.; POPIN, G. V.; MILORI, D. M. B. P.; SIGNOR, D.; DRUMOND, M. A.; CERRI, C. E. P. The substitution of native vegetation by agricultural ecosystems can change the quantity and quality of soil organic matter (SOM), and the intensity of these changes depends on the soil type, climate,... ... Repository: BDPA Publication year: 2017
Evaluation of the stability of soil organic matter in different types of livestock management. Author(s): THIAGO. N. O. de S.; SEGNINI, A.; XAVIER, A. A. P.; OLIVEIRA, P. P. A.; PEREIRA, D. M. B. Repository: BDPA Publication year: 2016
Evolution of the soil organic matter content after 15 years of crop livestock system. Author(s): VIANA, J. H. M.; ALVARENGA, R. C.; ALBUQUERQUE FILHO, M. R. de; COSTA, A. M. da; MOURA, M. S. de Soil organic matter (SOM) is sensitive to changes in land use and is a key indicator of soil quality. This work evaluates the evolution of the organic matter of an oxisol under a crop-livestock integr... ... Repository: BDPA Publication year: 2021
Changes in the soil structure and organic matter dynamics under different plant covers. Author(s): NOVAK, E.; CARVALHO, L. A.; SANTIAGO, E. F; TOMAZI, M. Repository: BDPA Publication year: 2019

C. de; FREIRE, M. B. G. dos S.; ALMEIDA, B. G. de; SANTOS, L. R. C. Deforestation of Caatinga and inadequate land use of these dry environments have impacted soil quality in Northeastern Brazil. The objectives of this study were: (a) to evaluate the effect of deforest... ... Repository: BDPA Publication year: 2022
Comparison of total nitrogen methods applied for histosols and soil horizons with high organic matter content. Author(s): PEREIRA, M. G.; ESPINDULA JÚNIOR, A.; VALLADARES, G. S.; ANJOS, L. H. C. DOS; BENITES, V. de M.; SCHULTZ, N. This study was carried out to correlate total nitrogen analyzed by two different methods: Kjeldahl (wet oxidation) and Perkin-Elmer 2.400 Series II-CHN Mode (dry oxidation or combustion) in Histosols... ...
