There are many benefits to selenium supplementation for crops, and growers should know these points

It was learned from the 3rd Beijing International High-Quality Agricultural Products Exhibition and Trade Fair that selenium supplementation for crops has been increasingly accepted worldwide, because selenium supplementation can improve soil activity, enhance crop quality, and strengthen human immunity.

According to relevant experts, selenium can improve soil compaction and salinization, promote plants' absorption of various nutrients, decompose organic matter in the soil, improve the soil's water- and fertilizer-retention capacity, and promote rooting and strong seedlings.

Increasing the selenium content of crops can regulate the growth environment of crop roots and stems, favor the reproduction and growth of beneficial microorganisms, and make crop root systems well developed.

Since selenium is a beneficial nutrient element in plants and animals, research shows that it has the effect of improving the immunity of animals and plants; therefore, selenium can be used as a trace additive in animal and plant feed to increase the selenium content of agricultural and sideline products.

At present, selenium has been regarded as an essential trace element for the human body. China is a selenium-deficient country. Selenium-deficient areas account for more than 70% of the national land area, and severely selenium-deficient areas account for 30% of the national land area.

However, due to reasons such as the continuous increase in agricultural yields and excessive land development, the soil in 80% of areas in China is currently deficient in selenium or even contains no selenium, resulting in generally low selenium content in the crops produced, which directly affects people's selenium intake. It is reported that the selenium content in the blood of normal Chinese people is far lower than the level of Americans.

Selenium supplementation can improve the quality and competitiveness of agricultural products and can also promote exports, and most Chinese people's constitutions need selenium supplementation. It should be noted that selenium existing in nature cannot be directly absorbed by the human body when consumed; only after being absorbed and transformed by animals and plants, converting inorganic selenium into organic selenium, can the human body possibly absorb it. Organic selenium has anti-cancer and anti-tumor effects.
