Abstract
Forages of the genus Urochloa can affect N dynamics in the soil, reducing its availability to maize grown in succession. The objective of this study is to assess the effect of Urochloa ruziziensis, Urochloa brizantha and Panicum maximum on soil N dynamics, evaluating: (i) the nitrification potential, (ii) ammonia, (Iii) the possible N output routes of the system as N2O and NH3 volatilizat…
