 Author(s): BRUNETTO, G.; CERETTA, C. A.; MELO, G. W. B. de; FELIPE, L.; PAULO, A. A. F.; COUTO, R. da R.; SILVA, L. O. S.; SOMAVILLA, L. M.; ADRIELE, T.; GARLET, L. P.; LESSANDRO, D. C.; COMIN, J. J.; LOVATO, P. E. Vineyard soils of the Campanha Gaúcha region of Rio Grande do Sul are sandy and have low to medium organic matter content, displaying low natural ability to supply nitrogen (N). Therefore, maintenance... ... |
 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... ... |

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): 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): MODESTO, V. C.; SOUZA, H. A. de; CAVALCANTE, A. C. R.; SALLES, H. O.; LIMA, A. R.; DIAS, C. T. dos S.; NATALE, W. Abstract: The correct management of fertilization, with the use of adequate source and doses of nitrogen, allied to cultivars adapted to certain edaphoclimatic conditions, is essential to obtain high... ... |
 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... ... |
