Charcoal (Biochar) as soil conditioner to enhance fertilizers and water use efficiency in agriculture in acid tropical soils in the Central Amazon Basin. Author(s): TEIXEIRA, W. G.; STEINER, C.; MARTINS, G. C.; ARRUDA, M. R. de This article summarize result of many experiments conducted in 15 years of research with biochar in nursery and field experiments in the Central Amazon. Repository: BDPA Publication year: 2014
Residual effect of nitrogen fertilizers formulated with biochar. Author(s): CARVALHO, T. A. de; PUGA, A. P.; PIRES, A. M. M.; LIGO, M. A. V.; ANDRADE, C. A. de Abstract: Biochar-based nitrogen fertilizers provide productivity and efficiency of nitrogen use gains, but knowledge is scarce about the residual effect for subsequent crops. We evaluated the residua... ... Repository: BDPA Publication year: 2019
Nutrient use efficiency in agricultural systems: a brazilian perspective. Author(s): BERNARDI, A. C. de C. Most Brazilian soils are deep, highly weathered, acidic, and of low natural fertility. Many strategies have been developed for building soil fertility using lime and mineral fertilizers, particularly... ... Repository: BDPA Publication year: 2024
Grain yield, efficiency and the allocation of foliar N applied to soybean canopies. Author(s): OLIVEIRA, S. M. de; PIEROZAN JUNIOR, C.; LAGO, B. C.; ALMEIDA, R. E. M. de; TRIVELIN, P. C. O.; FAVARIN, J. L. Soybean [Glycine max (L.) Merr.] grain yield is closely associated with the level of optimal nitrogen (N) supply, especially during the reproductive stages. Foliar fertilization with low rates of N ha... ... Repository: BDPA Publication year: 2019
Biochar, farmyard manure and poultry litter on chemical attributes of a Distrophic Cambissol and soybean crop. Author(s): PASSOS, A. M. A. dos; REZENDE, P. M. de; CARVALHO, E. R.; ÁVILA, F. W. de The use of organic wastes, as an alternative to inorganic fertilizer, can be an important strategy for Brazilian agriculture. The objective was to evaluate the residual effects and the agronomic effic... ... Repository: BDPA Publication year: 2015
Understanding N timing in corn yield and fertilizer N recovery: an insight from an isotopic labeled-N determination. Author(s): OLIVEIRA, S. M. de; ALMEIDA, R. E. M. de; CIAMPITTI, I. A.; PIEROZAN JUNIOR, C.; LAGO, B. C.; TRIVELIN, P. C. O.; FAVARIN, J. L. Early fertilizer nitrogen (N) application on cover crops or their residues during the off-season is a practice adopted in Brazil subtropical conditions under no-tillage corn (Zea mays L.) systems. How... ... Repository: BDPA Publication year: 2018
Phosphorus in Forage Production. Author(s): SERRA, A. P.; MARCHETTI, M. E.; DUPAS, E.; CARDUCCI, C. E.; SILVA, E. F. da; PINHEIRO, E. R. The aim in developing this work was to summarize information about phosphorus (P) limitation and dynamic in tropical soils for forage grasses production. The major idea is direct information about lim... ... Repository: BDPA Publication year: 2018
Soil solution and plant nitrogen on irrigated rice under controlled release nitrogen fertilizers. Author(s): VEÇOZZI, T. A.; SOUSA, R. O. de; SCIVITTARO, W. B.; WEINERT, C.; TARRILLO, V. R. C. Repository: BDPA Publication year: 2018
Productivity of corn and beans as affected by season and source of nitrogen. Author(s): SILVEIRA, P. M. da; NASCENTE, A. S.; CARVALHO, M. da C. S. Enhanced-efficiency fertilizers, which provide a reduction in nitrogen (N) losses, can be a viable alternative for the anticipation of topdressing for the moment of sowing, besides reducing operations... ...
