Carbon content in sandy soils under different use and management systems. Author(s): ARAUJO, A. R. de; MACEDO, M. C. M.; MAURO, R. de A.; SILVA, M. P. da; COSTA, J. A. A. da; FERREIRA, A. D. Quantifying soil carbon content is important to assess soil indicators related to adequate management conducted by producers in their agricultural systems. The objective of this study was to evaluate... ... Repository: BDPA Publication year: 2015
Soil chemical attributes for different land-use systems in semi arid region. Author(s): TONUCCI, R. G.; SOUZA, H. A. de Introduction the evaluation of soil fertility in already placed agroforestry systems allows inferences of greater managements practices and nutrient cycling. In the semi arid region the use of integra... ... Repository: BDPA Publication year: 2015
Soil solution chemistry in different land-use systems in the Northeast Brazilian Amazon. Author(s): FELIZZOLA, J. F.; FIGUEIREDO, R. de O.; TEIXEIRA, W. G. For sustainable production systems, the nonuse of fire (where there is a greater loss of soil nutrients), would be a solution for the conservation of nutrients in the soil, with the use of management... ... Repository: BDPA Publication year: 2022
Soil organic carbon temperature sensitivity of different soil types and land use systems in the Brazilian semi-arid region. Author(s): GOMES, T. C. de A. Quantifying the sensitivity of soil organic matter decomposition (SOM) to global warming is critical for predict future impacts of climate change on soil organic carbon stocks (SOC) and soil respirati... ... Repository: BDPA Publication year: 2019
Agroforestry system improves soil carbon and nitrogen stocks in depth after land-use changes in the Brazilian semi-arid region. Author(s): TONUCCI, R. G.; VOGADO, R. F.; SILVA, R. D.; POMPEU, R. C. F. F.; ODA-SOUZA, M.; SOUZA, H. A. de Abstract: Agroforestry systems have the potential to increase soil organic matter, with effects on soil carbon and nitrogen contents, but information on the application of these systems in semi-arid r... ... Repository: BDPA Publication year: 2023
Functional analysis of soil chemical attributes using Geographic Information Systems to assess nutrient deficiencies. Author(s): ARAUJO FILHO, J. C. de Information on soil fertility is essential to determine the need for correcting measures. However, the use of appropriate techniques to provide information on the specific potential of each soil in ma... ... Repository: BDPA Publication year: 2022
Gradients in N-cycling attributes along forestry and agricultural land-use systems are indicative of soil capacity for N supply. Author(s): NOGUEIRA, M. A. Indicators of soil quality associated with N-cycling were assessed under different land-use systems (native forest ? NAT, reforestation with Araucaria angustifolia or Pinus taeda and agricultural use... ... Repository: BDPA Publication year: 2012
Predicting soil organic carbon dynamics of integrated crop-livestock system in Brazil using the CQESTR model. Author(s): MADARI, B. E.; LEITE, L. F. C.; MACHADO, P. L. O. A.; CARVALHO, M. T. M. Land degradation and reduction in productivity have resulted in losses of soil organic carbon (SOC) in agricultural areas in Brazil. Our objectives were to 1) evaluate the predictive performance of CQ... ... Repository: BDPA Publication year: 2022
Microbial indicators of soil quality and soybean yield in agricultural production system using cover crops under no-tillage. Author(s): SOUZA, H. A. de; SAGRILO, E. Cover crops improve the physical, chemical and biological quality of the soil and boost crop yield. However, the magnitude of the effects on the microbial activity in tropical soils of Cerrado is stil... ... Repository: BDPA Publication year: 2023
