Effect of Different Irrigation Methods on Soil Nitrate and Ammonium Contents

In this study, the effect of irrigation methods were investigated on activity and leaching of soil ammonium and nitrate of nitrogen in the root zone (0-80 cm). The experiment was restablished as randomized plot of lands and to be contented with maise. In experiment the ammonium and nitrate has done with sowing one time. From effective root zone, during plant developing (0-20) cm in depth to take of sample in different time to do analysis with in the trial plot to fallow ammonium and nitrate and found loss. The effect of drip, furrow and sprinkler irrigation methods on ammonium and nitrate activity at root zone were not found significant It is because of that given irrigation water quantities were nearly same each other. In this study total amount of fertilizer distributed on the surface in one time and trough the first irrigation application more of them were leached. To percent the leaching nitrogen from the upper part of the root zone, it is recommented to give the total amount in time period.
