There are many microflora in soil such as bacteria, algae and fungi that affect soil properties
Are the bacteria present in the soil affecting soil erosion and physical and chemical properties such as pH, Ec, CEC, SAR, ESP, OM, TDS, SS, DR%, CaCo3, CaSo4, Fe, P, Cl, So4, K, N, Co3, Mg, Ca, Na, bulk density, Soil texture and heavy metal (Cu, Cd, Zn, pb)
IS there any link and articles and clues will be appreciated.
LA DEFORESTACION Y EL ARADO DEL SUELO DE CULTIVO COMO LA DESPROTECCION DEL SUELO CON CULTIVOS DE COBERTERA
Excessive grazing, deforestation, undesirable forest biota, and mechanical practices by man are important factors which cause soil erosion.
Biological factors refer to the human and plant activities that tend to reduce the quality of soil. Some bacteria and fungi overgrowth in an area can highly impact the microbial activity of the soil through bio-chemical reactions, which reduces crop yield and the suitability of soil productivity capacity. Human activities such as poor farming practices may also deplete soil nutrients thus diminishing soil fertility. The biological factors affect mainly lessens the microbial activity of the soil.
Do algae improve the properties of the soil and increase the bond between soil particles and thus reduce erosion by increasing organic matter
Since the question is specific, mentioning 'biological factors' affecting erosion in soil, it has to be addressed starting from the mechanistic processes of soil erosion. In this regard, the most important biological factor affecting soil erosion is the degree of vegetative cover which defines the extent of protection of the surface soil against raindrop impact. Another biological factor is soil microbial diversity which determines the rate of organic matter recycling and stabilization and the associated aggregation.
There are some biological factors which has indirect impact on soil as far as erosion is concerned, and these also has a driving affect on the abiotic factors. You can browse following links that will give baseline idea:

man should be considered as the most affective in erosion of rocks and soil..excavated load annually by big mechanical shovels , dredgers and other machines should exceed the action of all animals and plants..Is our brains a part of the living nature ..if so it's biological or biomechanical ..!
