Abstract
The nett gain or loss of total soil nitrogen was worked out from a long-term manure and fertilizer experiment conducted for seven years and still continuing at Ranchi Agricultural College, Kanke, Ranchi India. The total nitrogen in soil showed a deficit balance where lower and unbalanced doses of fertilizers were applied. Increasing levels of fertilizer combinations with lime removed the highest amount of nitrogen in intensive cropping. The nett loss was highest (95 kg/ha) in case of control, at 100% NPK the nett gain was 37 kg N per ha, and at 150% NPK 72 kg N per ha which was the highest.
