 ABSTRACT

The experiment was conducted to investigate the soil fertility status of the Varanasi district. The study consisted of field survey for collection of soil samples and their analysis for chemical and physical properties at department of Soil Science and Agricultural Chemistry, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi. Soil fertility evaluation of an area is an important aspect in context of sustainable agriculture production. The macro nutrients govern the fertility of soils and control the growth and yields of crops. In the present investigation four blocks was selected in the district Varanasi of Uttar Pradesh and studied the available macronutrient status in the soils using Parkers Nutrient Index approach made with the study of 30 sub-surface soil samples collected from farmers filed from different villages of Harhua, Baragaon, Pindra, Araziline block with the help of khurpi in zigzag motion. Collected soil samples were analyzed for pH, Electrical Conductivity,(EC) Organic Carbon (OC), Nitrogen (N), Phosphorus (P), Potassium (K) The Results reveals that the pH ranged from 6.6-8.7 with mean of 8.0 slightly acidic in nature, E.C. (dS m-1) ranged from 0.144-0.320 with mean of 0.22, Organic carbon ranged from 2.78-15.39 with mean value of 7.82 gkg-1 and available nitrogen, phosphorus, and Potassium were ranged from 158.4-455.5, 17.10-133.4 and 122.40-157.42 kg ha-1, respectively.

Key words: Soil fertility, Organic matter, Macronutrients, Nutrients index
