under Different Landuses.

Abstract
A general survey on N03 - - N levels in well-water under different landuses was conducted. Four areas were selected
to represent different landuses namely mixedfarming (crop and animal production), forest, urban, and crop production
only. Water samples from a total of 22 wells in the selected areas were collected and analysedfor N03- - N. The field
and statistical data showed that the differences in N03 - - N levels in well- waterfrom different landuses were significant
except for agriculture + animal farming. The highest N03 - - N level was observed in agricultural areas followed by
urban and forested areas.
