Soil algae may contribute a small amount of organic matter through their biomass but they do not have any active role in organic matter decomposition. These are not true soil organisms, but they continue their activity by taking part in the decomposition of organic matter and thereby release of plant nutrients in the soil. Soil organic matter (SOM) is the organic matter component of soil, consisting of plant and animal residues at various stages of decomposition, cells and tissues of soil organisms, and substances synthesized by soil organisms. Research output: Contribution to journal › Article Fouling of nanofiltration (NF) membranes is typically caused by inorganic and organic materials present in water that adhere to the surface and pores of the membrane and results in deterioration of performance (reduced membrane flux) with a consequent increase in costs of energy and early membrane replacement. The environmental and edaphic factors that control the activity of soil biota, and thus the balance between accumulation and decomposition of organic matter in the soil, are described below. Temperature: Cold periods retard plant growth and OM decomposition. Natural organic matter (NOM) fouling of NF membranes involves interrelationship between physical and chemical interactions and it is described in this review. The rate of decomposition is more in neutral soils than that of acidic soils. Soil Factors Affecting Heavy Metal Solubility in Some New Zealand Soils. Membrane fouling in the presence of NOM can be influenced by: membrane characteristics, including surface structure as well as surface chemical properties, chemistry of feed solution including ionic strength, pH and concentration of monovalent ions and divalent ions, NOM properties, including molecular weight and polarity, and hydrodynamic and operating conditions including permeate flux, pressure, concentration polarization, and the mass transfer properties of the fluid boundary layer. All these factors operate within a hierarchical spatial scale. increased precipitation warmer temperatures increased winds. are applied as manure in arid regions, the slender moisture in the soil may be largely used up for the decomposition of O.M. Too much moisture leads to insufficient aeration which results in the reduced activity of microorganisms and there by checks the rate of decomposition. Corresponding Author.
