Biochar phosphate fertilizer loaded with urea preserves available nitrogen longer than conventional urea
(Multidisciplinary Digital Publishing Institute (MDPI), 2022)
RESIDUAL EFFECTS OF NITROGEN FERTILIZER WITH POLYMER-COATED UREA IN A CORN CROP
(Univ Fed Rural Semi-arido-ufersa, 2017-07-01)
The use of nitrogenous fertilizer coated by polymers may reduce losses caused by volatilization, thus exposing this element to plants for a longer period of time. The objective of this work was to evaluate the residual ...
Productivity and efficiency of nitrogen fertilization in maize under different levels of urea and NBPT-treated urea
(Editora da Universidade Federal de Lavras, 2011)
Volatilization of ammonia from conventional sources of nitrogen and compacted urea under controlled conditions
(Univ Federal Rural Pernambuco, 2020-01-01)
Urea is the most used nitrogen fertilizer in tropical agriculture, but when applied to the soil surface, it can promote nitrogen (N) losses by volatilization of ammonia (NH3). The present study aimed to evaluate, under ...
Application of different nitrogen doses to increase nitrogen efficiency in Mombasa guinegrass (Panicum maximum cv. mombasa) at dry and rainy seasons
(2017-12-01)
Nitrogen is the nutrient that most influences productivity and pasture quality but nitrogen fertilization efficiency still needs to be increased. The objective of this work was to study the efficiency of nitrogen sources ...
