 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): GIROTO, A. S.; VALLE, S. F. do; GUIMARÃES, G. G. F.; WUYTS, N.; OHREM, B.; JABLONOWSKI, N. D.; RIBEIRO, C.; MATTOSO, L. H. C. Agricultural output needs significant increases to feed the growing population. Fertilizers are essential for plant production systems, with nitrogen (N) being the most limiting nutrient for plant gro... ... |
 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): 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): BRAZ, A. J. B. P.; FERREIRA, C. J. B.; SILVEIRA, P. M. da; SIMON, G. A.; ASSIS, R. L. de; BRAZ, G. B. P.; MEDEIROS, R. V. The efficiency of new fertilizers as a nitrogen source in super-early cycle common bean cultivars still needs to be better known. The objective was to quantify the effect of new sources and time of ap... ... |
 Author(s): BERNARDI, A. C. de C.; SOUZA, G. B. de; POLIDORO, J. C. The zeolite and urea mixture may be use to improve N efficiency use of silage corn. The objective of this study was to evaluate dry matter yield, quality components and nutritional levels of nitrogen... ... |
 Author(s): MAGALHÃES, C. A. de S.; SANTOS, B. L. da S. dos; PETTER, F. A.; MATOS, E. da S.; FURTINI, I. V.; MORALES, M. M. Abstract: This study aimed to evaluate the effects of soil texture, fertilizer formulation and nitrogen dose on the characteristics of upland rice production, and to compare the Agronomic Efficiency I... ... |
 Author(s): RECH, I.; POLIDORO, J. C.; PAVINATO, P. S. The objective of this work was to develop urea-based fertilizers with internal incorporation of urease inhibitors and other additives in the granule. The effects of the incorporation of NBPT, copper (... ... |
 Author(s): BRUNETTO, G.; CERETTA, C. A.; MELO, G. W. B. de; GIROTTO, E.; FERREIRA, P. A. A.; LOURENZI, C. R.; COUTO, R. da R.; TASSINARIA, A.; HAMMERSCHMITT, R. K.; SILVA, L. O. S. da; LAZZARETTI, B. P.; KULMANN, M. S. de S.; CARRANCA, C. In Brazilian vineyards planted in sandy soils, nitrogen (N) should be applied at optimal rates and timing that correspond to greatest demand, thus minimizing N losses. The aim of this study was to eva... ... |
 Author(s): PAULA, B. V. de; VITTO, B. B.; SETE, P. B.; TRAPP, T.; ZALAMENA, J.; MELO, G. W. B. de; BALDI, E.; TOSELLI, M.; ROZANE, D. E.; BRUNETTO, G. Nitrogen (N) fertilizers such as urea are applied to peach orchards worldwide whenever the soil cannot meet plants? N demand. However, the actual nutritional contribution of different N supply modes a... ... |
