Even land that has lost all its soil -- or where no soil ever existed -- can be revegetated. Using the method shown, up to a foot of soil can be created in three years, even in arid areas.

The basic process is simple:
This process can also be used on areas that retain soil but have insufficient forage to feed livestock. Where adequate but undesirable forage exists (such as yellowstar thistle or annual grasses in areas that once supported perennials), well-managed grazing at high density will shift succession toward more desirable species. Examples.
In arid or highly brittle areas where soil life is marginal, avoid all poisons. Herbicide-sprayed "weed free" hay, shed hair from cattle that have been deloused, dung with deworming medications or other biocides, all have enough toxins to kill soil life and delay successful seedling establishment for 3 years or more.

Improving soil health and building new soil (articles). Soil health is vital to ecosystem health. How to build new topsoil and restore the health of damaged soils using managed grazing. Includes examples of successful soil-building on sites with no soil at all.
Working with soil life (articles). Soil organisms, particularly fungi that help plant roots absorb nutrients, are vital to maintaining soil health and building new soil. The organisms present affect which nutrients are available and which plants can grow and thrive. Soil life can be seeded, its activity measured, and its health promoted by good management.
