Soil fertility status of some villages in Sader block of Balasore district under North Eastern coastal plain agro climatic zone of Odisha, India

Abstract

A soil fertility status inventory work was carried out in some villages of Sader Block belonging to Balasore district located in the North Eastern coastal plain Agro Climatic Zone of Odisha, India. Results showed that Soil pH ranged between 5 and 8.1. Soil Organic Carbon (SOC) content ranged between 0.43 to 13.1 g kg-1. Available nitrogen content varied in between 57.5 to 285 kg ha-1. Available phosphorus content varied from 0.7 to 31.5 kg ha-1. Available potassium content varied widely from 40 to 558 kg ha-1. DTPA extractable micronutrient (Fe, Mn, Zn and Cu) varied from 36.8 to 150, 10.8 to 38.9, 0.2 to 0.8 and 1.3 to 2.05 mg kg-1 respectively. Hot water soluble boron content ranged from 0.08 to 1.94 mg kg-1. Most of lower range were found in upland soils while the higher values for all the parameters were found in low land soils.
