The urea transporter DUR3 is differentially regulated by abiotic and biotic stresses in coffee plants. Author(s): SANTOS, T. B. dos; BABA, V. Y.; VIEIRA, L. G. E.; PEREIRA, L. F. P.; DOMINGUES, D. S. The high costs of N fertilizers in the coffee production emphasizes the need to optimize fertilization practices and improve nitrogen use efficiency. Urea is widespread in nature, characterizing itsel... ... Repository: BDPA Publication year: 2021
Polymer-coated urea in broadcast or furrow application in the corn-palisadegrass intercropping system. Author(s): ALMEIDA, R. E. M. de; FAVARIN, J. L.; OLIVEIRA, F. B.; PIEROZAN JUNIOR, C.; OLIVEIRA, S. M. de; LAGO, B. C.; TEZOTTO, T.; OTTO, R.; TRIVELIN, P. C. O. Polymer coated urea (PCU) have the potential to increase nitrogen (N) use efficiency (NUE) by the release of N following crop demand while reducing losses by volatilization, leaching and denitrificati... ...

Zinc loading in urea-formaldehyde nanocomposites increases nitrogen and zinc micronutrient fertilization efficiencies in poor sand substrate. 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... ... Repository: BDPA Publication year: 2022
Coated and common urea as affecting upland rice production. Author(s): NASCENTE, A. S.; FAGERIA, N. K.; STONE, L. F. The objectives of this study were to evaluate performance of polymer coated and common urea in upland rice growth, yield and yield components. Repository: BDPA Publication year: 2014
Urea levels in multiple supplement for lambs grazing on buffelgrass. Author(s): VOLTOLINI, T. V.; MORAES, S. A. de; ARAUJO, G. G. L. de; OLIVEIRA, P. L. T. de; PEREIRA, L. G. R. The objectivo of present trial was to evaluate the intake of supplement dry matter, productive performance, carcass traits, and weight and yields of commercial meat cuts of lambs grazing on dormant bu... ...

Urochloa ruziziensis responses to sources and doses of urea. Author(s): LIMA, J. E. S.; NASCENTE, A. S.; LEANDRO, W. M.; SILVEIRA, P. M. da The use of products that promote reduction of nitrogen (N) losses from the urea fertilizer can contribute to increasing its use efficiency in forage grasses. This study aimed to evaluate the effects o... ... Repository: BDPA Publication year: 2016
Biodegradable oil-based polymeric coatings on urea fertilizer: N release kinetic transformations of urea in soil. Author(s): BORTOLETTO-SANTOS, R.; GUIMARÃES, G. G. F.; RONCATO JUNIOR, V.; CRUZ, D. F.; POLITO, W. L.; RIBEIRO, C. Polymer coatings are used to control the rate of release of plant available nutrients from fertilizers as well as to reduce nutrient losses such as ammonia (NH3) volatilization.Although the literature... ...
