Abstract
A field experiment was carried out during the year 2024 in the Department of Soil Science & Agricultural Chemistry, School of Agriculture, ITM, Gwalior. Surface (0-15 cm) and sub surface (15-30 cm) soil sample were collected by systematic survey with location data using global position system from CRC-1 farm, ITM, Gwalior District, Madhya Pradesh. A total numb of collected soil sample was 120 sample. pH was varied between 7.21 to 8.69 at 0–15 cm depth and 7.18 to 8.57 at 15–30 cm depth. The pH is slightly alkaline. The Electrical conductivity (EC) ranging from 0.23 to 0.52 dsm-1 at 0 -15 cm depth and 0.31 to 0.59 dsm-1 at 15 -30 cm depth emphasizing that the fact that the soil is safe limit of EC. Organic carbon was varied between 0.31 to 0.39% in 15–30 cm depth and 0.35 to 0.42% in 0–15 cm depth. The OC status is low to medium. Nitrogen (N) was ranged between 134.5 to 139.9 kg ha-1 at a depth of 0–15 cm and 132.4 to 135.5 kg ha-1 at a depth of 15–30 cm. Phosphorus(P) ranging from 8.42 to 12.20 cm at 0–15 cm depth and 6.28 to 10.68 cm at 15–30 cm depth. Potassium (K)ranging from 8.42 to 12.20 kg ha -1 at 0–15 cm depth and 6.28 to 10.68 kg ha -1at 15–30 cm depth. Sulphur(S) was ranged between 15.36 to 20.54 kg ha-1 at a depth of surfaced and 13.64 to 18.74 kg ha -1 at a depth of sub surfaced.
