Selenium Distribution in Soils of Bio-Climatic Zones of Haryana

The distribution of Se in profiles from bio-climatic zones of Haryana was studied. Total Se ranged from 1 to 10.5 ppm. In high rainfall areas (> 500 mm) like Rohtak, Sonepat, Kurukshetra and Ambala, Se content increased with depth. A higher total Se was related to higher CaCO₃, clay and org. matter contents which showed positive significant correlations. The avail. Se was highest in surface soil. In Karnal highest avail. Se (0.41 ppm) was recorded. Available Se showed highly significant positive correlations with clay and iron. Available Se ranged from 3.1 to 36.0 per cent of total Se.
