Soil fertility status in Taluks of Chitradurga district under zero budget natural farming of Karnataka

Abstract

The study was conducted to evaluate the nutrient status of selected villages under six taluks of Chitradurga District. For this purpose, 854 surface soil samples were collected from six taluks of Chitradurga district in Karnataka. The results showed that soil pH varied from 6.00-8.00 slightly acidic to slightly alkaline and EC is non-saline nature. Soils were found to be low to high in available nitrogen (46-400 kg kg N ha) and samples fall under medium to high available phosphorus (>22.50 kg P ha) category. The available potassium status in surface soils of different talukas ranged from 94.08 to 685.44 kg ha. Available sulphur content in soil varied from 2.85 to 24.60 kg ha-1. Among the 854 samples of the six taluks, Maximum soil samples area showing sufficient in zinc status, only
