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
Short-term effect of adding nitrogen in forest soil of an urban rainforest. Author(s): NASCIMENTO, B. M.; CESÁRIO, F. V.; BALIEIRO, F. de C.; RODRIGUES, R. de A. R.; WANDERLEY, H. S. The deposition of atmospheric nitrogen has been increased in urban forest ecosystems, yet it is not clear how this increase affects soil respiration in the short term. The soil respiration could contr... ... Repository: BDPA Publication year: 2020
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... ...
