dc.description.abstractA long-term field experiment, going on at the research farm, Department of Soil Science, CCS HAU, Hisar, since Rabi-1967, was selected for present investigation. The treatments consisted of three times of FYM application (in Kharif, Rabi and both seasons), three levels of FYM application (15, 30 and 45 Mg FYM ha-1), one control and three levels (0, 60 and 120 kg N ha-1) of fertilizer nitrogen application through urea. Long-term effect of FYM and N application on uptake of sulphur, iron and manganese by wheat crop were estimated. Application of different levels of FYM and N significantly increased the yield as well as the uptake of sulphur, iron and manganese by wheat crop. Highest uptake of sulphur, iron and manganese was found in 45 Mg FYM and 120 kg N ha-1 in both seasons treated plots followed by Rabi and Kharif. Long-term FYM and N application effect was also studied on different fractions of sulphur, iron and manganese in soil at surface (0-15 cm) and sub-surface (15-30 cm) level. Increasing level of FYM application increased the content of sulphur, iron and manganese in all fractions. Highest content of sulphur, iron and manganese in all fractions was recorded in plots receiving FYM 45 Mg ha-1 in both seasons followed by Rabi and Kharif. Higher amounts of sulphur, iron and manganese was found in surface soils as compared to sub-surface soils, except carbonate bound iron and manganese, whose contents were slightly higher in the sub-surface soils than surface soils. The percent contribution of different fractions of sulphur to total sulphur in soil at surface and sub-surface depths were in the following order: Organic sulphur > residual sulphur > heat soluble sulphur > sulphate sulphur > water-soluble sulphur and the percent contribution of different fractions of iron and manganese to total iron and manganese in soil at surface and subsurface depths were in the following order: Residual > organically bound > oxide bound > carbonate bound > exchangeable. The fertilizer N application did not significantly affect any of the sulphur, iron and manganese fractions in soil at surface and sub-surface level.en_US
