Abstract

In order to make an opinion about the secondary and micronutrient status of Hodal block soils (Palwal), 50 surface soil samples were collected with the help of auger and coordinates of each sample were recorded with the help of a global positioning system. The high spatial variability of nutrient distribution, which made it difficult to ensure representative sampling, and the lack of historical soil data, limiting long-term comparative analysis. The results indicated that the mean value of exchangeable calcium and magnesium was 4.05 and 7.92{Cmol (p⁺) kg⁻¹}, respectively,and sulfur was 68.15 mg kg-1. The mean value of DTPA extractable zinc, iron, copper, manganese, and hot water-soluble boron was 0.64, 6.77, 0.82, 4.05, and 1.51 mg kg⁻¹, respectively. The majority of the soil samples of DTPA extractable Zn (90%), Fe(56%) and Mn (84%) were found under the deficient category, where soil samples of Cu(56%) and B (84%) were found under the sufficient category. The DTPA-extractable Zn exhibited a significant negative correlation with DTPA-extractable Cu and hot-water soluble B, while Cu showed a significant positive correlation with hot water-soluble B. Additionally, Ca demonstrated a significant positive correlation with electrical conductivity. This study provides essential baseline information on the nutrient profile of Hodal soils, offering a scientific foundation for developing targeted soil fertility and nutrient management strategies to improve crop productivity in the region.
