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.

Both for post-operative injuries and those fractures that do not require surgery, the use of an immobilizer boot will be required. Depending on the nature of the fracture you may or may not have to keep all weight off the leg as it heals. Fractures in general take six to eight weeks to completely heal. Fibula fractures occur generally with trauma or are associated with lateral ankle sprains. â¢ Fractures of the fibula do not always require surgery. Size, location, and stability of the fracture will determine if you are a surgical candidate. â¢ Fractures will require immobilization and six to eight weeks to heal.
