Importance of humic substances for stabilizing soil aggregates and central reactions explanation in soil : a review

الملخص EN

Humic substances have an essential function in soil fertility and are viewed as being of prime importance for soil aggregation stability.

Humic substances as part of humus-soil organic matter are chemicals generated from the biomolecules physically, chemical and microbiologically (humifying).

It is essential since it is the most pervasive biological material source, which nature knows.

Roughly 80 percent of total carbon is produced with terrestrial humic compounds and 60 percent of the water dissolved carbon.

During the last three decades there have been challenges in two major approaches, the concept of soil humic substances.

Much of the organic aromatic soil originates from the carbon that is frequently known as black carbon (black carbon).

However, the detection of benzene polycarboxylic acid markers and the UV technique in soil with two commonly used methods is not trustworthy.

Polymerisation of phenolic compounds produced from the breakdown and synthesis of lignin microorganisms may result in a wide number of humic chemicals and components including organic molecules and inorganic molecules.

The addition of e.

g.

, triazines or tensile compounds that cause to bound residues in the humic matrix demonstrates that humic substances are crucial for clarifying critical soil processes.

Plant nutrients, comprising p, fe and cu, are available in soil this is equally essential to understand and can directly influence the growth of higher plants in the soil.
