Nitrate-Nitrogen Leaching from Onion Bed under Furrow and Drip Irrigation Systems
Figure 4
Cumulative N fertilization (kg ha−1), cumulative N uptake (kg ha−1) and monthly soil N (kg ha−1) during two onion growing seasons each in furrow- (2006–09) and drip-irrigated (2006–08) onion fields in NM. NAE is the nitrogen application efficiency.
