Abstract:
This study was focussed to assess the physico-chemical properties in soil around different blocks of Ganjam district Odisha. Depth wise soil samples were collected from nine Major cropping systems of selected spots at 0-15, 15-30 and 30-45 cm. Total 27 samples were selected for analysis. The results revealed that soil colour varied from brown colour to Very dark greyish brown in dry condition while from Very dark greyish brown to yellowish brown in wet condition. The texture was mostly sandy loam, sandy clay loam and loamy sand. The bulk density ranged from 1.271 to 1.813 (Mg m-3), particle density from 2.221 to 3.336 (Mg m-3), pore space from 30.94 to 51.62 (%), water holding capacity from 40.95 to 66.67 (%), specific gravity from 2.07 to 2.52. The pH ranged from 6.217 to 6.643, E.C. ranged from 0.041 to 0.178 (dS m-1). The soil organic carbon ranged from 0.668 to 1.141 (%). Available nitrogen ranged from 131.45 to 268.19 (kg ha-1), Available Phosphorous ranged from 10.01 to 15.78 (kg ha-1). Ammonium extractable Potassium ranged from 233.68 to 295.56 (kg ha-1) all of which showed decrease in value with increase in depth. Exchangeable calcium ranged from 0.7 to 8.3 (cmol (p+) kg-1), exchangeable magnesium ranged from 0.8 to 5.5 (cmol (p+) kg-1) and available sulphur ranged from 0.76 to 5.35 (pp all of which varied significantly with site and depth. The results indicated that farmers required maintaining soil health card, adopting suitable management practices and providing proper nutrition to the soil to beat the pollution effect.
