What Is Humic Acid? Humic and Fulvic acids are the final break-down constituents of the natural decay of plant and animal materials. These organic acids are found in pre-historic deposits. Humic matter is formed through the chemical and biological humification of plant and animal matter and through the biological activities of micro-organisms.
Properties of humic substances. Humic acids - the fraction of humic substances that is not soluble in water under acidic conditions (pH 2) but is soluble at higher pH values.They can be extracted from soil by various reagents and which is insoluble in dilute acid. Humic acids are the major extractable component of soil humic substances.

Liquid Fulvic Acids extracted from black humus peat is an extremely potent and high-energy substance that stimulates plant metabolism, increases stress tolerance and acts as a natural detoxifier. An organic fulvic acid concentrate that improves photosynthesis, and nitrogen efficiency and can balance and maintain higher soil nutrient levels.
Humic substances are weak acidic electrolytes with carboxylic- and phenolic-OH groups with a micelle-like structure and with a molecular weight between 500 (fulvic) and 100,000 (humic). The chemical structure of humic acid is shown in Figure 6.1 . They become hydrophobic as pH decreases, and thus foul hydrophobic membranes more .

Two humic acids (HAs) were isolated from contaminated river sediments present under comparative conditions in the Pearl River Basin, China. YFHA (the HA extracted at an open pyrite mining area in Yunfu) exhibited a lower absorption intensity for certain bands in the Fourier transform infrared spectra, a lower E 4 /E 6 value (the UV absorbances at 465 nm (E 4) and 665 nm (E 6)), a lower
The degree of polymerization of fulvic acid is thought to be less than humic acid (Manahan, 2000) but the hygroscopic growth below 100% RH is very similar for reference humic and fulvic acids of
The maximum TC adsorption capacity of PSs in the presence of humic acid (50.99 mg/g) was higher than that of PSs (44.77 mg/g) at pH 6.0. The highly effective adsorption was attributed to electrostatic attraction, π-π interaction and hydrophobic effect, which was determined by FT-IR and XPS analysis.
Dragon Herbs High Mountain Shilajit is collected from a very high altitude source in the Western Himalayas. It has been laboratory tested for authenticity and purity. Dragon Herbs High Mountain Shilajit contains over 50% fulvic acids and equivalents, the richest available in America to our knowledge. It contains 40 different minerals.
About 50 years back at Kherson University a young Soviet scientist named Lydia Khristeva made an important discovery. Using ordinary soil, she educed humic acids from the samples as a solution of sodium salts and then watered plants with the solution. The plants had increased growth and an increased root mass over the control plants.

Heterogeneous ice nucleation on particles composed of humic‐like substances showed that humic acid sodium salt and leonardite can nucleate ice via deposition mode but this study was (for the remainder of the manuscript referred to as substrate) from a tip of a syringe using ultra high‐purity N 2 gas as carrier gas. The
natural leonardite new growth regulators sodium humate agricultural fertilizer is black granular or powder, soluble in water, alkaline, has the functions of ion exchange, adsorption, complexation, flocculation, decentralization and adhesive bonding.It has the prominent property to absorb toxins, which decide this product is naturally an important feed additive to poultry and fish.
After a 7-day decay to allow Na-24 to decay the samples are counted on a high purity Ge detector with resolution of better than 1.7 keV for the 1332 keV Co-60 photopeak. Analysis results are given
The influence of different reaction conditions on the yield of syringaldehyde was studied by using perovskite oxide as the catalyst. The optimal reaction conditions are as follows: 0.60 g of dealkali lignin, 0.60 g of 5 wt % theta ring-loaded LaFe0.2Cu0.8O3 catalyst, 30 mL of 1.0 mol/L NaOH solution, 160 °C reaction temperature, 0.80 MPa O2 pressure, and 2.5 h reaction time. Under these
To evaluate ultraviolet C (UV-C) irradiance, UV-C dosage, and antimicrobial effect achieved by a mobile continuous UV-C device.Prospective observational study.We used 6 UV light sensors to determine UV-C irradiance (W/cm ) and UV-C dosage (µWsec/cm
Biochar is probably quite good for sandy soils. Even a single 50# bag of good clay per acre every year would seriously help the low cation exchange capacity (CEC) that that sand has. Not only does organic matter burn off, but nutrients leach very fast from pure sand. Good biochar has a high CEC. Good clay has a high CEC, too. And clay can't
