In this article. DMSO, or dimethyl sulfoxide, is a by-product of paper making. It comes from a substance found in wood. DMSO has been used as an industrial solvent since the mid-1800s.MSO is easily absorbed by the skin. It's sometimes used to increase the body's absorption of other medications. DMSO is available without a prescription most often in gel or cream form.
Actual soil fertility is the amount of nutrients and moisture derived from the soil by the plants in a given year.
The fine grains weather rapidly due to their large surface area, making soils derived from loess very rich. One theory states that the fertility of loess soils is due largely to cation exchange capacity (the ability of plants to absorb nutrients from the soil) and porosity (the air-filled space in the soil).
