Effect of cover crops on physico-chemical attributes of soil in a short-term experiment in the southwestern Amazon region. Author(s): PASSOS, A. M. A. dos; AKER, A. M.; COSTA, R. S. C. da; SANTOS, F. C. dos; LEITE, V. P. D.; MARCOLAN, A. L. No-tillage is an agricultural system that is proposed as a sustainable soil management system. This paper aims to evaluate the short-term effects of cover crops on a no-tillage system, by assessing a... ... Repository: BDPA Publication year: 2017
Sugarcane trash levels in soil affects the fungi but not bacteria in a short-term field experiment. Author(s): RACHID, C. T. C. C.; PIRES, C. A.; LEITE, D. C. A.; COUTINHO, H. L. C.; PEIXOTO, R. S.; ROSADO, A. S.; SALTON, J.; ZANATTA, J. A.; MERCANTE, F. M.; ANGELINI, G. A. R.; BALIEIRO, F. de C. The sugarcane in Brazil is passing through a management transition that is leading to the abolition of pre-harvest burning. Without burning, large amounts of sugarcane trash is generated, and there is... ... Repository: BDPA Publication year: 2016
Initial root length in wheat is highly correlated with acid soil tolerance in the field. Author(s): PEREIRA, J. F. ABSTRACT: In acid soils, toxic aluminum ions inhibit plant root growth. In order to discriminate aluminum (Al) tolerance, trustful screening techniques are required. In this study, 20 wheat cultivars,... ... Repository: BDPA Publication year: 2018
Soil hydrophysical and chemical attributes in ferralsol amended with wood biochar. Author(s): LUCON, I. M.; CARNIER, R.; COSCIONE, A. R.; ANDRADE, C. A. de; JÚNNYOR, W. da S. G.; MARIA, I. C. de Abstract: Most studies concerning biochar, which can enhance chemical, physical, and biological soil qualities and increase crop yields, are short-term experiments in controlled environments with temp... ...

Enzyme activities in a sandy soil of Western Bahia under cotton production systems: short-term effects, temporal variability, and the FERTBIO sample concept. Author(s): LOPES, A. A. DE C.; BOGIANI, J. C.; FIGUEIREDO, C. C. DE; REIS JUNIOR, F. B. dos; SOUSA, D. M. G. de; MALAQUIAS, J. V.; MENDES, I. de C. Enzyme activities (EAs) and the FERTBIO sample concept have been increasingly adopted as a novel approach to estimate the soil quality in Brazil. However, the performance of this strategy in sandy soi... ... Repository: BDPA Publication year: 2021
Short-term and long-term effects of natural and artificial carbonaceous substrates on greenhouse gas fluxes. Author(s): KERN, J.; LIBRA, J.; AMMON, C.; NEUBAUER, Y.; TEIXEIRA, W. G. The emissions of two greenhouse gases (GHG), carbon dioxide (CO2) and nitrous oxide (N2O), from six substrates with different carbonaceous content were compared in short and long-term incubation exper... ...

Population structure correction for genomic selection through eigenvector covariates. Author(s): AZEVEDO, C. F.; RESENDE, M. D. V. de; SILVA, F. F. e; NASCIMENTO, M.; VIANA, J. M. S.; VALENTE, M. S. F. We proposed a population structure correction for genome-wide selection based on covariance analysis via eigenvector (EVG) decomposition. The agreement between the predicted and true breeding values w... ... Repository: BDPA Publication year: 2017
Effect of nitrogen fertilization on soil microbial biomass in an Oxisol cultivated with irrigated barley in the Brazilian Cerrado. Author(s): DINIZ, L. T.; RAMOS, M. L. G.; RIBEIRO JUNIOR, W. Q.; CRUZ, A. F.; FRANCA, L. V. de; DINIZ, B. T.; AMABILE, R. F. Abstract:The aim of this study was to evaluate the effect of different nitrogen doses and five period of sample collection, on soil microbial biomass - nitrogen (SMB-N), total nitrogen (total N) and p... ...
