For native hardwood trees, topsoil substitutes should be neutral to slightly acid, sandy and loamy in texture, loose and wellaerated for good drainage, fertile without excessive saltiness, and the selected material should be 4 or more feet deep. For forestry postmining uses, and when FRA procedures are used, regulations in

How To Rebuild Fertile Topsoil After Mining. Topsoil Management Plan . This Topsoil Management Plan (TMP) has been prepared to demonstrate how topsoil will be preserved in a condition as near as possible to its premining condition in order to allow successful mine rehabilitation.
#0183;#32;A degraded soil typically loses its ability to supply food and habitation to living organisms, in its surrounding. When this happens, effort is made to restore the soil back to its natural state. Characteristics of a degraded soil include: high salinity, decline in fertility, decline in organic matter (leading to decline in soil structure), soil
When mining operations are complete, the overburden material is reapplied and leveled and then the topsoil is reapplied and spread over the overburden material to provide a planting medium (USDA Forest Service RM447). Both removal and replacement of the soil layers involves the use of heavy equipment.
#0183;#32;Some organic farming techniques that help restore the soil include use of green manure (uprooted or sown crop parts incorporated or left on topsoil), cover crops, crop rotation and organic compost. Green manure and cover crops: Green manures and cover crops serve as mulch to the soil preventing the soil from wind/water erosion and moisture loss.
#0183;#32;Many soils formed after glaciers retreated are only about 10,000 to 20,000 years old, but have thick topsoils. Other soils formed in materials that were already physically weathered and deposited by moving water or wind, allowing topsoil to form much faster. Second, outside of glaciated areas we have had a very long time to form soil.
Once workers finish mining, they usually lay down nutrientpoor soil, called overburden, instead of nutrientrich topsoil that is more difficult to store during the lengthy mining process
