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.

Usually, when the shaft of the tibia is broken the fibula, the smaller bone of the lower leg, is broken as well. This bone serves mainly as an anchor point for muscle and hardly bears any weight. As a result it does not need to be perfectly straight when it heals.n the case of an isolated fracture of the fibula you may be able to walk, but with nearly all other fractures it is impossible to bear weight. Within a few minutes of the injury the leg will swell up. If there have been injuries to the nerves or arteries the foot may be numb or cold.
