Assessment of Soil Quality Indicators of Soil from Different Departments of NAI, SHUATS, Prayagraj

Abstract

An assessment of soil health parameter properties of soil from different departments of NAI, SHUATS, Prayagraj carried out during 2022-23. The prime objectives of this study were to carry out the soil health parameter properties of soil at different depths of various department research farm to determine the availability of macronutrients and micronutrients in soil of these soil sample provide the assessment 7 sampling locations were selected. Soil samples were collected with depth of 0-15, 15-30 and 30-45 cm respectively. The soil colour dry condition varied from Light yellowish brown, dark yellowish brown, Pale olive, pale brown, pale yellow, Light olive brown, Yellowish brown, Olive yellow, Dark brown and in wet condition varied from Olive brown, Olive, Dark brown, Dark yellowish brown, light olive brown, Olive yellow and Dark yellowish. The soil texture was dominantly sandy loam in every site. The bulk density ranged from 1.170 to 1.432 Mg m⁻3. The Particle density ranged from 2.22 to 2.50 Mg m⁻3. The pore space ranged from 42.50 to 51.24 %. The soil pH ranged from 7.37 to 7.78. The electrical conductivity ranged from 0.28 to 0.44 dS m-1. The soil organic carbon ranged from 0.16 to 0.42%. The available nitrogen ranged from 195.5 to 256.0 kg ha-1. The available phosphorous ranged from 14.43 to 23.95 kg ha-1. The available potassium ranged from 132.00 to 206.00 kg ha-1. The available calcium ranged from 0.97 to 1.88 cmol (p+) kg-1. The available magnesium ranged from 0.76 to 1.69 cmol (p+) kg-1. The available zinc ranged from 0.60 to 0.72 mg kg-1. There is an including awareness of the need to pay greater attention in the role of macronutrients enhancement in the soil for good soil health and proper nutrition of plant so as to attain optimum economic yield and soil is suitable for all major tropical and sub-tropical crops.
