Do cover crops compete with young grapevines for fertilizer nitrogen? 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... ... Repository: BDPA Publication year: 2016
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
Response of low land rice to nitrogen fertilization under different irrigation regimes. Author(s): REIS, A. B.; FAGERIA, N.; SILVA, L.; VASCONCELOS, A.; FAVARIN, J. The objective of this study was to evaluate response of irrigated rice to nitrogen fertilization under different irrigation regimes. Repository: BDPA Publication year: 2014
Organic nitrogen in a typic hapludox fertilized with pig slurry. Author(s): GROHSKOPF, M. A.; CASSOL, P. C.; CORREA, J. C.; MAFRA, M. S. H.; PANISSON, J. The application of pig slurry may have a different effect on nitrogen dynamics in soil compared to mineral fertilization. Thus, the aim of this study was to determine the different forms of organic N... ... Repository: BDPA Publication year: 2015
Fertilizers with coated urea in upland rice production and nitrogen apparent recovery. 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... ... Repository: BDPA Publication year: 2016
Gas exchange in Massai grass fertilized with nitrogen and grazed by sheep. 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... ... Repository: BDPA Publication year: 2020
Tillering dynamics in massai grass fertilized with nitrogen and grazed by sheep. Author(s): LOPES, M. N.; CÂNDIDO, M. J. D.; POMPEU, R. C. F. F.; SILVA, R. G. da; MORAIS NETO, L. B. de; CARNEIRO, M. S. de S. To evaluate the tillering dynamics of massai grass under rotational sheep stocking and fertilized with nitrogen (control - 0; 400; 800 and 1200 kg ha-1 year-1), this study was carried out, in a comple... ...
