Leaching of nitrate from a sandy loam soil under corn and two N-fertilizations
Nitrate losses in two undisturbed soil1ysirneters cultivated with corn under irrigation and fertilization (higher in Ll than in L2) were studied. Total drained water volume during the experimental period was higher in L2 than in Ll. Differences can be attributed both to different patterns of soil water dynamics and crop development in each lysimeter. Nitrate losses were higher in Ll than in L2 and occurred mainly during the crop season. This abnormal nitrate losses distribution seems to be due to the scarcity and uneven distribution of rainfall during autumn 1992.

Summary: | Nitrate losses in two undisturbed soil1ysirneters cultivated with corn under irrigation
and fertilization (higher in Ll than in L2) were studied. Total drained water volume during the
experimental period was higher in L2 than in Ll. Differences can be attributed both to different
patterns of soil water dynamics and crop development in each lysimeter. Nitrate losses were
higher in Ll than in L2 and occurred mainly during the crop season. This abnormal nitrate losses
distribution seems to be due to the scarcity and uneven distribution of rainfall during autumn 1992. |
