Soil and land resources of Maddikonda village are diversified in nature and characteristics in supplying nutrients and providing necessary anchorage for the crop growth and development. There are number of variations in growth and disparities in the packages adopted by farmers. In the study area as a result of non-addition of organic manures, and primarily depending on chemical fertilizers, most of the soils exhibiting number of nutrient deficiencies i.e. N,P,K. The increasing nutrient deficiency retards the crop growth, yield and their quality characteristics. Keeping in view of problem, in the present investigation the fertility status of the soils of Maddikonda village, Bhadradri Kothagudem district of Telangana was evaluated on key parameters viz., physico-chemical, available macro nutrient status using Nutrient Index approach by analysing 131 surface soil samples for pH, Electrical Conductivity (EC), Organic Carbon (O.C.), Nitrogen (N), Phosphorus (P) and Potassium (K). The Results of the study revealed that soils of the soils of Maddikonda village are very strongly acidic to neutral in reaction (4.19 to 7.54) with a soluble salt content ranges from 0.02 to 0.24 dS m-1 (Non-saline) and organic carbon content varied from 0.39 to 0.52% (low in status). The nitrogen status varied from 88.2 to 403.2 kg ha-1 and most of the soils of field cropped area are low in nitrogen status, soil phosphorus status ranged from 6.5 to 88.6 kg ha-1 and most of the soils are medium to high in phosphorus and potassium ranges between 57.8 to 310.1 kg ha-1 which indicates low to medium in potassium status.

Nutrients index, soil physico chemical properties, nutrient mapping

From the above results it concluded that Maddikonda village is having neutral to strongly acidic soils which are non saline soil and low in organic carbon content. In terms of macro nutrient content soils are low to medium in nitrogen content, medium to high in phosphorous availability and low to medium in potassium availability. These map details will further, help in fertilizer recommendation and helps in improving the crop yield and sustainability.
