ABSTRACT
An investigation was carried out to study micronutrient status in cotton growing soils of Chamarajanagar district of Karnataka. Results revealed that the soils of Chamarajanagar district belong to sandy clay loam to clay loam texture with pH of 7.48 to 9.80 and electrical conductivity varied from 0.02 to 4.12 dSm-1. In most of the soils, Phosphorus, Sulphur, Manganese were limited in availability and organic carbon low in rating in most of the soils. Available (DTPA-extractable) Fe, Zn, Mn and Cu status of these soils ranged from 4.96 to 7.50 ppm, 0.06 to 0.81 ppm, 0.66 to 5.65 ppm, and 0.20 to 0.39 ppm respectively and the hot water extractable boron content of the soils ranged from 0.04 to 20 ppm. Zinc and Boron content was deficient in entire cotton growing soils of the district.
Key words :
Cotton growing soils, Micronutrient status, Organic carbon, Physio-chemical properties.
