Assess the Sulphur Fractions in Soil as Affected by Soil Test Based Nutrient Application

Abstract

A field experiment was conducted during Kharif, 2019 at research field of Department of soil science and agricultural chemistry, JKKVV, M. P. India. Assess the sulphur fractions in soil as affected by soil test based nutrient application. The experiment was laid out in RBD with six treatments with four replications. The treatment schedule was having Control, General Recommended Dose (120-60-40), Targeted yield of 50 q ha-1 (138-65-60), Targeted Yield of 60 q ha-1 (178-86-79), Targeted Yield of 50 q + 5 t FYM ha-1 (134-50-57) and Targeted Yield of 60 q + 5 t FYM ha-1 (174-71-76) respectively. The result of this study showed that relationship between N, P, K and FYM used in soil increased the available S, water soluble S, organic S and total S in the soil. The increase of S fractions with the application of NPK might due to synergistic effect of N-S, P-S Or K-S in the soil. The application of NPK nutrients for T.Y.60q (174-71-76) + 5 t FYM resulted maximum available S (19.94 kg ha-1), water soluble S (16.96 kg ha-1), heat soluble S (25.17 kg     ha-1), organic S (44.28 kg ha-1) and total S of (112.72 kg ha-1) which were significantly higher to General recommended dose for available, water soluble, heat soluble, organic, total S fraction in post-harvest soil.
