dc.description.abstractThe soils of all blocks were alkaline in reaction (7.73-8.90). The soils were non saline as the electrical conductivity of Nathusari Chopta, Rania, Sirsa, Baragudha, Odhan, Ellenabaad and Dabwali blocks was 0.49, 0.53, 0.54, 0.56, 0.63, 0.41 and 0.50 d S m-1, respectively. The soil texture ranged from sandy loam to clay loam. The organic carbon content of Sirsa district ranged from 0.21-0.82% with a mean value of 0.54%. About 57 percent soils were in medium category followed by 26 and 16 percent in low and medium category. The highest very labile carbon (0.20%) and labile carbon (0.12%) values were being observed in sandy soils whereas minimum were observed in clay loam and sandy loam soils, respectively. The highest less labile (0.20%) and recalcitrant (0.43%) carbon was observed in clay loam soil whereas minimum were observed in sandy soils. Similarly the highest total organic carbon (0.81%) was observed in clay loam soil. The mean available N was lowest in Nathusari Chopta and highest in Rania block. The highest available nitrogen (150.01 kg ha-1) and available phosphorus (33.41 kg ha-1) were recorded in Rania block whereas minimum available nitrogen (118.60 kg ha-1) and available phosphorus (22.60 kg ha-1) were recorded in Nathusari Chopta block. The soils were low in available nitrogen whereas high in available phosphorus. The available potassium in all blocks ranged between 96 to 650 Kg/ha. The mean value of available K was lowest in Nathusari Chopta (225.17) and highest in Odhan (278.86) block. The soils were medium (58%) to high (33%) in available potassium. The minimum and maximum levels of available S were found in the Blocks Rania (113.08) and Nathusari Chopta block (63.53) respectively. Around 54 percent samples were high in available suphur whereas only 10 percent samples were in low category. Most of the farmers using nitrogen fertilizer as above recommended dose, phosphorus fertilizer as recommended dose and potassium fertilizer as below recommended dose.en_US
