The mean microbial concentration after 45 d of supplementation of humic acids increased 14% in the essential groups (P < 0.01), 28% (NS) in the individual pioneer groups and 41% (P < 0.002) in the individual substantial groups. The accidental bacterial groups with initially marginal concentrations demonstrated no response to humic acids. The response to humic acids […]
Humic substances are complex organic substances of soil, which are formed in the process of humification. Humification involves natural chemical and microbial activity that transforms the dead remains of living things into humic substances.
The sum concentration of colonic microbiota increased from 20% at day 10 to 30% by day 31 and remained stable until day 45 (32%) of humic acid supplementation (P < 0.001). The increase in the concentrations in each person was due to growth of preexisting groups. The individual microbial profile of the patients remained unchanged. Similarly, […]
Potassium humate is important in agricultural production ,due to Potassium humate is a high-efficiency organic potassium fertilizer, because humic acid is a biologically active preparation, which can increase soil available potassium content, reduce potassium loss and fixation, increase crop potassium absorption and utilization, and improve Soil, promote crop growth, improve crop resilience, improve crop quality, and protect agricultural ecosystems. With the deepening of the concept of balanced fertilization, the source of humic acid has been accepted by more and more people, and is expected to be high. This article will introduce the effect of potassium humate.
Potassium humate possesses a wide variety of oxygen-containing functional groups and has good adsorption and complexion properties for many kinds of transition metal ions. In this work, a simple and separable route had been developed to synthesize Fe3O4/graphene nanocomposite, derived from potassium humate, were employed for the effective adsorption of Cr(VI) in aqueous phase. In addition, the Fe3O4/graphene nanocomposite prepared […]
