Analysis of NH3-N slow release systems for fiber digestibility of low-quality forage: in vitro approach. Author(s): CRUZ, C. C. T. da; PEREIRA, E. I.; SATO, P. S.; GUIMARÃES, G. G. F.; SOUZA, G. B. de; BERNARDI, A. C. de C.; OLIVEIRA, C. R. de Urea is a common non-protein supplement used in ruminant feed; however, excessive consumption may lead to poisoning by NH3. Although the slow release of urea into the rumen has shown to be an essentia... ... Repository: BDPA Publication year: 2020
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
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
Brazilian sedimentary zeolite use in agriculture. Author(s): BERNARDI, A. C. de C.; OLIVEIRA, P. P. A.; MONTE, M. B. de; POLIDORO, J. C.; SOUZA-BARROS, F.

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
Urease inhibitors of agricultural interest inspired by structures of plant phenolic aldehydes. Author(s): HORTA, L. P.; MOTTA, Y. C. C.; BARBOSA, G. M.; BRAGA, T. C.; MARRIEL, I. E.; FÁTIMA, A. de; MODOLO, L. V. The plant phenolic natural products (PNPs) protocatechuic aldehyde, syringaldehyde and vanillin were used as platforms for obtaining four urease inhibitors. Urea (urease substrate) or thiourea (urease... ... Repository: BDPA Publication year: 2016
