[12] [13] [14] Humins can also be subjected to thermal treatments in order to form interesting solid materials, such as lightweight and porous humin foams. [ 15 ] [ 16 ] Overall, humins appear to improve the final properties of the materials although research is mainly at the proof-of-principle stage (early).
These benefits can include increased tolerance to abiotic stressors, improved soil texture and water retention, and reduced occurrence of diseases. [ 1 ] [ 3 ] On a broader socio-ecological scale, seaweed aquaculture and fertilizer development have significant roles in biogeochemical nutrient cycling through carbon storage and the uptake of ...
Humic substances account for 50 – 90% of cation exchange capacity in soils. "Humic substances" is an umbrella term covering humic acid, fulvic acid and humin, which differ in solubility. By definition, humic acid (HA) is soluble in water at neutral and alkaline pH, but insoluble at acidic pH < 2. Fulvic acid (FA) is soluble in water at any pH.
Humic substances are classified into three genera based on their solubility in acids and alkalis, and also according to their stability: Fulvic acid is the genus that contains the matter that has the lowest molecular weight, is soluble in acids and alkalis, and is susceptible to microbial action.
Potassium humate is used in agriculture as a fertilizer additive to increase the efficiency of fertilizers especially nitrogen- and phosphorus-based fertilizer inputs. Other salts of humic acid are manufactured, mainly sodium humate, which is used in animal health supplements. It also can be used in aquaculture.
The solid residue of sewage sludge treatment, which is a secondary phase in the wastewater treatment process, is also called humus. [10] When not judged contaminated by pathogens , toxic heavy metals , or persistent organic pollutants according to standard tolerance levels, it is sometimes composted and used as a soil amendment .
The International Humic Substances Society was founded in Denver, Colorado, USA, on September 11, 1981 by scientists who saw a need for a society to bring together scientists in the coal, soil, and water with interest in humic substances, and to provide opportunities for them to exchange ideas .
Lawns and Home Gardens The United States Environmental Protection Agency mentions that biosolids that adhere to the most rigorous standards for reducing pollutants, pathogens, and attractiveness to vectors can be bought by individuals from hardware stores, home and garden centers, or directly from their community's wastewater treatment facility ...
