Humic Acid Powder is in black color and insoluble in water itself, it has high content of organic matter and humic acid, and is milled from leonardite or lignite sources. Humic Acid Balls is in made from humic acid powder and has high content of humic acid and organic matter. It improves the soil condition by application Humic Acid Granules is meshed out from natural leonardite or lignite souces, it is irregular shapes, high in organic matter and humic acid content Potassium Humate Powder is in black color and soluble in water.It is extracted from natural leonardite or lignite powder. It has several grades for different applications. Potassium Humate Flakes is derived from leonardite or lignite powder, it has high content of humic acid and water solubility. Sodium Humate Powder is made from leonardite with NaOH, it is water soluble , it is widely used in agriculture, industrial and livestock feedings and milled from sodium humate shiny flakes, sodium humate crystals and dry-method. Sodium humate has lowest content of HA, not is most economy products

what is Tartaric acid ? Tartaric acid is commonly used in the preparation of medicines, mordants and tanning agents, and is also commonly used as a reagent for the resolution of racemic basic compounds. It is also a sour agent in food additives, sourness is better than malic acid, lactic acid and so on. Several of its salts have important applications. For example, the Fehling reagent is formulated with potassium sodium tartrate in the laboratory to identify aldehyde functional groups in the structure of organic molecules. Its potassium and sodium salt is also called Rochelle's salt. Its crystals are polarized under pressure to produce a potential difference (piezoelectric effect) on both ends of the surface, which can be made into piezoelectric elements for radio and cable broadcasting. The receiver and pickup. Medically, potassium antimony tartrate (commonly known as tartrate) is used to treat schistosomiasis L-tartaric acid Storage: Stockpiled at the ventilated place, avoiding rain, moisture and insolation. Please handle with care to prevent bag damage, store away from toxic substances.
