One of the biggest degrading factors for soil productivity and health is the effect of soil erosion. As soil erosion is mitigation soil can become better as the building progress is enhanced and the erosive process lessened.
I look to mycorrhiza fungus playing a fundamental role in stabilization and accural of soil organic matter. The web of mycorrhizal fungi extend a network of connection that greatly reduce soil erosion and greatly enhance the soil genesis process. The glomalin glyco proteinaceous compounds enhance the soil aggregation process which retards soil erosion and these same compounds are largely decay resistant enhancing the soil organic matter accumulation.
The mass of fungal material is a critical component. In the soil 20% of the photosynthetic products are secreted into the root zone. The development of the fungal network is preserved by not over tilling and by maintaining soil covers and the persistent of the living covers in particular accelerate the top soil formation process.
Earthworms and fauna are also critically important for the accelerated soil formation. The earthworm activity is a soil aggregation power house the large calcium glands in the earth worm can lead to a detoxification in the earthworm digestive process and the castings are of a near perfect aggregate size with them being a biological soil aggregate generator.
A single earthworm in a year can produce 5 kg of castings and in a well wormed improved legume grass paddock with manure the numbers of worms per hectares reach into millions.
The use of paddocks with intensive grazing and the animal plant rotation is a way to advance a rapid and conclusive soil regeneration and to improve the C and N stocks of soils counteracting the issues with GHG and global warming.
By improving the soil environment the productivity of animals and plants and the ecosystem and economics can be optimized and the issues with climate GHG and global warming addressed.
