Author(s): CARVALHO, M. da C. S.; NASCENTE, A. S.; TEIXEIRA, P. C. Urea is the most used N fertilizer for upland rice, however, a great percentage of N loss can occur with the use of this fertilizer. The use of products that provide reduction of N loss for urea ferti... ... |
Author(s): LOPES, M. N.; CÂNDIDO, M. J. D.; POMPEU, R. C. F. F.; SILVA, R. G. da; LACERDA, C. F. de; BEZERRA, M. A.; MORAIS NETO, L. B. de; CARNEIRO, M. S. de S. The knowledge of gas exchanges in forage plants is essential for a better understanding of the process of forage biomass production in pasture. This study evaluated the gas exchange in massai grass fe... ... |
Author(s): BERNARDI, A. C. de C.; POLIDORO, J. C.; MONTE, M. B. de M.; PEREIRA, E. I.; OLIVEIRA, C. R. de; RAMESH, K. Tropical soils require liming and a balanced nutrient supply to ensure high crop yield and quality. An adequate agronomic nutrient management involves balanced nutrition and fertilizers are the key fa... ... |

Author(s): SILVA, M. A. S. da; SANTOS, A. B. dos; MADARI, B. E.; CARVALHO, M. T. de M.; PRICE, A.; MENDONÇA, P. L.; MASCARENHAS, Y. S. The objective of this study was to find a feasible alternative to the use of nitrogen fertilizers for smallholders and commercial farming in tropical flooded rice systems. |
Author(s): BERNARDI, A. C. de C.; MOTA, E. P da; SOUZA, S. do C. H. de; CARDOSO, R. D.; OLIVEIRA, P. P. A. The nitrogen loss by ammonia volatilization is one of the main factors for low efficiency of N-urea applied on the soil surface. The reduction of losses by volatilization can be obtained with the addi... ... |
Author(s): CONTRERAS ESPINAL, F. S.; SILVA, E. C. da; MURAOKA, T.; FRANZINI, V. I.; TRIVELIN, P. C. O.; TEIXEIRA, M. B.; SAKADEVAN, K. The use of green manures (GMs) in combination with nitrogen (N) fertilizer application is a promising practice to improve N fertilizer management in agricultural production systems. The main objective... ... |
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... ... |
Bean plant lineages submited to the nitrogen fertilization and to the Rhizobium tropici inoculation. Author(s): BRITO, O. R.; OTSUBO, A. A.; MERCANTE, F. M.; HORI, A. E.; OTSUBO, V. H. N.; SCHNITZER, J. A.
