Summary
The balance sheet of phosphorus and potassium were worked out from a long term manure and fertilizer experiment conducted for eight years and is still continuing at Ranchi Agricultural College, Kanke, Ranchi, India. Increasing levels of fertilizer combination with organic manure and lime give the highest yield as well as removed the highest amount of phosphorus and potassium from the soil and gave the positive gain of soil phosphorus and potassium in intensive cropping. The highest gains of 59.0 and 278.0 kg/ha of phosphorus and potassium respectively were recorded in 150% NPK application.
