Evaluations of soil fertility status of available major nutrients (N, P & K) and micro nutrients (Fe, Mn, Cu & Zn) in Vertisol of Balodabazar block in Balodabazar district of Chhattisgarh

Abstract

Evaluation of the soil fertility status of Vertisol group of Balodabazar block of Balodabazar district of Chhattisgarh was carried out during 2016-17. Grid-based surface (0-15 cm) soil samples were collected by systematic survey from 55 villages in Balodabazar block in such that each 10 ha area represented one sampling point and total 2170 soil samples covering all soil types out of this, 1346 samples were identified from Vertisol. The available N content ranges from 105 to 263 kg ha-1 with mean values 197 kg ha-1, The average available P content ranged from 1.5 to 34.9 kg ha-1 with an average value of 18.0 kg ha-1 and the available potassium content ranges from 115-643 kg ha-1 with an average value of 417 kg ha-1. The available Fe content ranges from 2.40 to 44.12 mg kg-1 with mean values 16.46 kg ha-1, The average available Zn content ranged from 0.20 to 3.00 mg kg-1 with an average value of 0.95 mg kg-1, available Cu content ranges from 0.20 to 3.00 kg ha-1 with an average value of 1.81 kg ha-1 and available Mn content ranges from 2.20 to 45.76 kg ha-1 with an average value of 23.85 kg ha-1.
