Journal of the Indian Society of Soil Science v. 34, no. 2, p. 271-274617379Summary: Different forms of soil nitrogen were determined after fifteenth crop in a long-term experiment involving soybean-potato-wheat, receiving fertilizers and manures. Positive and significant correlations between NO3-N and water soluble, exchangeable and fixed NH4+ were obtained. Also, fixed NH4+ was correlated significantly with water soluble and exchangeable NH4+. Total nitrogen uptake byfive crops of soybean, potato and wheat were significantly related to water soluble, exchangeable and fixed NH 4-N, NO3-N and available N. Path analysis also indicated the greater contribution of NO3 and fixed ammonium N to soybean and wheat and water soluble NH4+ and
