Is Indian soil rich in selenium?
Loss of selenium rich soil has reduced the dietary availability of selenium, thus increasing the deficiency of this micronutrient worldwide [18]. India is a vast country with wide geographical soil status. In one study, the northern part of India was reported to have normal levels of soil selenium [19] .
What is considered low selenium in soil?

Selenium deficiency regions in New Zealand, Denmark and the Atlantic Region of Canada contain 0.1 to 0.6 mg Se kg‐1 in the soil.

What causes low selenium levels?
Rainfall, evaporation, and pH levels all affect selenium concentration in soil. This makes selenium deficiency more common in certain parts of the world. In the United States, selenium deficiency is rare.
Why is Michigan selenium poor?
Selenium (Se) deficiency is associated with selenium deficient soils and the inadequate uptake of selenium by forages grown on these soils. Certain areas of the U.S., including Michigan, are considered low in selenium levels. Vitamin E deficiency is independent of soil type and more closely reflects forage quality.
