Selenium Toxicity in Some Plants and Soils of Punjab

Selenium toxic areas were identified on the basis of selenium content of plant and soil samples. Soil samples containing more than 0.5 ppm Se were associated with plant samples falling in the toxic range (i.e >5 ppm Se) for animal consumption. Toxic limit for soil samples is therefore, proposed to be 0.5 ppm Se. Selenium content of plants wasfound to be significantly related with S content of plants. total and available selenium. CaCO₃, silt and clay content of soils. Total and available Se content of soils showed significant relationship with salinity. CaCO₃ sand and silt content.
