what is soil biomass

Soil Biology and Biochemistry. Millar W.N. and Schmidt E.L. 1977. Eds Ellwood D.C., Hedger J.N., Latham M.J., Lynch J.M. and Larsen R.I. 1976. The principal forms of organic P in soils are phosphate monoesters like inositol hexakisphosphate (phytate) (ranging from 2% up to 80% of organic P), phospholipids (1-5% of organic P), nucleic acids (0.2-2.5% of organic P), and less prevalent components like phosphoproteins, sugar phosphates, and monophosphorolated carboxylic acids (Stevenson, 1994). Examples of biomass sources are wood products, dried vegetarians, crop residues, aquatic plants, and much more. 1972. 1982. and Gerdemann J.W. Rhodes L.H. and Snyder W.C. John Murray.

Due to the high specific surface and CEC of SOM, it is an important sorbent of plant macronutrients and micronutrients, heavy metal cations, and organic materials such as pesticides.

For example, manure additions can enhance micronutrient availability in alkaline soils where precipitation of the micronutrients at high pH reduces their availability. This process lowers atmospheric CO2 concentrations, thereby mitigating a contributor to future climate-change threats. Therefore, humic substances (humic acids, fulvic acids, hymatomelanic acids, and humins; [79]) are relatively more stable and resistant to decomposition. [89] identified general response profiles of C cycling enzymes after pesticide exposure, showing an inhibition effect of dehydrogenase activity, activation of cellulose especially by insecticides, and no clear response of β-glucosidase. This sage is … On the contrary, fungicides and insecticides might have a more direct toxic effect on faunal communities (e.g., [85,88,105]), affecting the processes in which they are involved such as SOM breakdown (e.g., [91,106–108]).

Similarly, the potential of a P-solubilizing fungus Penicillium balaji to increase the availability of RP to Triticum aestivum and Phaseolus vulgaris depended on mycorrhizal activity (Kucey, 1987; Kucey et al., 1989).
