Le résumé fourni par la source

A study was conducted during 2023–24 to assess the soil fertility status of agricultural lands in Amalipadar Village, located in Chhattisgarh. The primary objective was to evaluate the macro- and micronutrient status of soils and develop nutrient management recommendations for improving crop productivity. A total of 160 surface soil samples (0-15 cm) were collected from farmer’s fields and analyzed using standard laboratory procedures. Soil physico-chemical properties, including pH, electrical conductivity (EC), and organic carbon, along with available macronutrients and micronutrients, were determined and interpreted using the Nutrient Index Value (NIV) approach. The soil pH ranged from 6.02 to 7.91 with a mean value of 6.60, indicating slightly acidic to neutral reaction. Electrical conductivity varied from 0.05 to 0.23 dS m- ¹ (mean 0.14 dS m- ¹), suggesting absence of salinity hazards. Organic carbon content ranged from 2.17 to 7.59 g kg- ¹ with an average of 5.84 g kg- ¹. Available nitrogen ranged from 125.44 to 275.9 kg ha- ¹ (mean 209.87 kg ha- ¹), phosphorus from 4.25 to 37.95 kg ha- ¹ (mean 16.61 kg ha- ¹), and potassium from 112.23 to 553.10 kg ha- ¹ (mean 284.95 kg ha- ¹). Available sulphur content varied between 1.26 and 35.53 kg ha- ¹ with a mean of 24.83 kg ha- ¹. DTPAextractable micronutrient analysis showed that iron (6.26–37.67 mg kg- ¹; mean 14.71 mg kg- ¹), manganese (3.57–21.45 mg kg- ¹; mean 6.78 mg kg- ¹), and copper (1.00–2.90 mg kg- ¹; mean 1.54 mg kg- ¹) were generally sufficient. However, zinc levels (0.25–0.41 mg kg- ¹; mean 0.27 mg kg- ¹) were deficient in all sampled soils. The results highlight the need for balanced fertilization with special emphasis on zinc supplementation to enhance soil fertility and sustain crop productivity in the region.
