Description
Nitrogen fertilization is one of the largest investment when recovering and intensifying pasture management. Urea nitrogen use efficiency was studied in Brachiaria brizantha pasture under tropical conditions where liming was applied to the soil in two dates ("early" and "late" - March and August, respectively). Lime was broadcasted and urea was either broadcasted or subsurface-band applied. "Early" applied lime caused 16,4% increase in forage dry matter yield in the rainy season. Urea-N recovered in the shoots was higher when subsurface band applied independently from time of lime application.
