Abstract
The results of investigation conducted on the coastal sand, red sandy loam and laterite soils with four slow release nitrogen sources for their nitrogen release pattern in the laboratory have been reported. Ureaform recorded low exchangeable ammonium and urease activity than all other slow release sources used. The ureaform released ammonical, nitrate and urea nitrogen for more than 105 days irrespective of the soils. In laterite, urea and neem cake coated urea registered significantly high nitrate nitrogen. In all the soils, nitrite nitrogen was recorded upto 45 days only. Neem cake blended urea and urea blended with neem cake and coal tar showed higher nitrate nitrogen.
