Soil nitrogen contribution to grasslands and its implication for nitrogen use efficiency

Soil nitrogen contribution to grasslands and its implication for nitrogen use efficiency

In pasture systems of southern Chile, nitrogen (N) fertilization is mostly carried out without considering soil N supply, while seasonal N plant uptake is partially accounted for. These aspects are fundamental to correctly decide N fertilization. The aim of this work was to determine soil N contribu...
