A consequence of deforestation is typically large-scale erosion, loss of soil nutrients and sometimes total desertification. Techniques for improved soil conservation include crop rotation, cover crops, conservation tillage and planted windbreaks, affect both erosion and fertility. When plants die, they decay and become part of the soil.
For riparian revegetation, plant roots help to increase the shear strength of bank soil, and if tree roots begin to lose their strength, the bank is susceptible to land slips. Fibrous or matted roots in particular help to prevent against soil erosion, and are typically found in reed and sedge species. [6]

The Great Plains Shelterbelt was an American initiative to create shelterbelts on the prairies in the USA during the dustbowl of the 1930s.; The Prairie Farm Rehabilitation Administration in Indian Head, Saskatchewan, Canada subsidized seedlings to prairie farmers for almost 100 years to reduce soil erosion and increase quality of life on the prairies.
Wood chips are an easy and affordable way to give your garden a boost. They're commonly used as mulch to suppress weeds, improve water retention, and reduce soil erosion.Beyond mulch, wood chips ...
Cover crops manage soil erosion, soil fertility, soil quality, water, weeds, pests, diseases, biodiversity and wildlife in an agroecosystem—an ecological system managed and shaped by humans. Cover crops can increase microbial activity in the soil, which has a positive effect on nitrogen availability, nitrogen uptake in target crops, and crop ...
The least soil loss was obtained with NT-CV 0.02 tons ha-1. [20] The reduction of water runoff and erosion is one of the greatest advantages of having a cover crop. Soil can be easily eroded with no vegetative ground cover or plant residue. Ideally soil erosion should be less than 4 to 5 tons/ha/year. [21]
Tilling the soil, or tillage, is the breaking of soil, such as with a plough or harrow, to prepare the soil for new seeds. Tillage systems vary in intensity and disturbance. Conventional tillage is the most intense tillage system and disturbs the deepest level of soils. At least 30% of plant residue remains on the soil surface in conservation ...
