Question

Why is there decrease in level of minerals in the soil?

Answer 1

Hey mate here is your answer.


The idea has certainly been promoted a lot in the last 20 years. Our food is less nutritious than it used to be and the main reason is that soils are being depleted of nutrients. There is also a big movement to remineralize our poor soils. Hopefully, adding things like rock dust will bring it back to historical levels.

Soil minerals serve as both sources and sinks of essential plant nutrients. As primary minerals that originally formed at high temperatures and pressures in igneous and metamorphic rocks are weathered in soils, they release plant nutrients into the soil solution.

Some of the most common minerals found in soil are, Iron, Potassium, Magnesium, Calcium, Sulphur etc. Humus: Humus is the organic substances that are formed due to decomposition of dead and decomposing plants and animals. It lends the soil its fertility.
