The concentration of SOM in soils generally ranges from 1% to 6% of the total topsoil mass for most upland soils. Soils whose upper horizons consist of less than 1% organic matter are mostly limited to desert areas, while the SOM content of soils in low-lying, wet areas can be as high as 90%.Soils containing 12-18% SOC are generally classified as organic soils.he concentration of SOM in soils generally ranges from 1% to 6% of the total topsoil mass for most upland soils.

Young women tend to take less time healng from a broken pelvic bone than men do.
