Soil heavy metal levels exceed standards - is the fruits and vegetables grown still safe to eat?

At present, heavy metal levels exceeding standards in China's cultivated land are serious, posing a huge threat to agricultural product safety. How can people swallow with peace of mind the grain and vegetables grown from such land?

Solving the problem of soil heavy metal pollution has become urgent, and using microbial fertilizer can effectively improve contaminated soil.

How does microbial fertilizer remediate soil contaminated by heavy metals?

Microbial fertilizer contains a large number of highly active bacterial strains, such as nitrogen-fixing bacteria, lactic acid bacteria, Bacillus species with different functions, and so on. Through a series of their own life activities, these beneficial bacteria degrade and dissolve heavy metals in the soil, reducing their concentration or toxicity, and even converting them into completely harmless substances.

In addition, only heavy metals in the active state in soil can be absorbed by crops. The level of heavy metal activity is affected by soil properties. In highly acidic soil, the activity of heavy metals increases, and the amount absorbed and utilized by crops increases.

The beneficial bacteria in microbial agents can break up soil compaction, make the soil permeable to water and air, and thereby regulate soil pH, avoiding excessive acidity or alkalinity. Therefore, they can reduce the activity of heavy metals and greatly reduce the amount absorbed and utilized by crops.

Using microbial fertilizer to remediate soil contaminated by heavy metals is not only remarkably effective, but also more economical and environmentally friendly than conventional physical and chemical remediation methods, with no need to worry about secondary pollution. It is currently a scientific and efficient way to solve the problem of soil heavy metal pollution.
