Physico-Chemical properties under soybean growing area of Nagpur District


NA Khadse, VP Babhulkar and Sharad Pophle

The study on nutrient status in relation to soil properties for growing soybean was under taken at HingnaTahsil of Nagpur district, Maharashtra during the year 2014-2015. Five farms at distinct location growing soybean were selected for soil profile study. The soils of study area having colour ranging from very dark gray (10YR 3/ 1M) to yellowish brown colour (10 YR 4/4). Structure was granular to sub angular blocky in surface and sub angular blocky structure in sub surface horizons. Sand, silt, clay content in the soils varied from 4.7 to 12.8, 24.6 to 36.6, 51.9 to 68.6% respectively. Bulk density varied from 1.38 to 1.63 Mg m<sup>-3</sup>. The saturated hydraulic conductivity ranged from 1.73 to 2.38 cm hr<sup>-1</sup>. The soils reaction was neutral to slightly acidic (6.26 to 7.65) The WHC range from 47.4 to 63.9 organic carbon values decreases with depth and ranged from 0.231 to 0.684 g kg<sup>-1</sup>. The pH found Increasing with depth ranging from 7.65 to 8.50. The Electrical conductivity (EC) ranged from 0.16 to 0.34dSm<sup>-1</sup>.The available major nutrient content in soils were available Nitrogen ranged from 140 to 244 kg ha<sup>-1</sup>,available Phosphorus ranged from 2.21 to 8.16 kg ha<sup>-1 </sup>and available Potassium ranged from 219 to 422 kg ha<sup>-1</sup>. As regards with available Sulphur status it varied from 3.03 to 8.73 kg ha<sup>-1</sup>.The Ca<sup>2+</sup> and Mg<sup>2+</sup> of soils were varied from Ca<sup>2+</sup> 21.7 to 45.6 C mol (p+) kg<sup>-1</sup> and Mg<sup>2+</sup> 9.2 to 19.1 C mol (p+) kg<sup>-1</sup>.The DTPA extractable micronutrient status in soils were, Fe content varies from 6.1 to 8.7 mg kg<sup>-1</sup>, Mn content varies from 3.41 to 5.02 mg kg<sup>-1</sup>, Zn content varies from 0.36 to 0.58 mg kg<sup>-1</sup>, and Cu content varies from 0.59 to 2.94 mg kg<sup>-1</sup>. In correlation studies between physico-chemical properties of soils and soybean yield were evaluated to know the relationship and found that soybean yield is adversely affected because of soil higher pH and EC however, yield positively influenced by all major and micro nutrients. The physical properties like clay and BD are responsible for reducing the yield however, saturated hydraulic conductivity and water holding capacity can increase the yield.In correlation studies of various soil major and micro with physical, chemical properties.
