Nitrate-Nitrogen Leaching from Onion Bed under Furrow and Drip Irrigation Systems
Figure 3
NO3-N/Cl ratio at a 0–200 cm soil depth during two onion growing seasons in furrow- (2006–09) and drip-irrigated (2006–08) onion fields in NM. The vertical bars represent standard errors of the mean. Each data point is the mean of three replicate samples.
