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.

It depends upon which bones are broken, the degree of bone displacement and other issues. If the bones are large (tibia, fibula) and not displaced, you're looking at about nin â¦ e weeks. If you have broken many smaller bones you may be looking at a recovery of six months or more, if there are complications.t depends upon which bones are broken, the degree of bone displacement and other issues.
