Secondary nutrients and chloride content of tobacco growing soils of Prakasam district, Andhra Pradesh

Abstract

The present study was carried out by collecting 100 representative soil samples from tobacco growing soils of Prakasam district. The soils were found to be neutral to moderately alkaline in reaction. All the soil samples were non-saline. The exchangeable calcium was found to be the most dominant cation followed by magnesium on soil complex which ranged from 3.10 to 35.80, 0.20 to 8.50 cmol (p+) kg-1, respectively and medium content of sulphur. The average chloride content was 43.85 which varied from 14.20 to 86.00 ppm, which comes under highly suitable and suitable classes for tobacco cultivation. About 89 percent soil samples were highly suitable and remaining 11 percent soil samples were suitable for tobacco cultivation.
