Terminology of Humus-related Materials

Humus–product resulting from decay of organic matter. Contains both humic and non-humic material. Humin–the alkali-insoluble fraction of leonardite. (The usage of this term does not correspond exactly with the usage by other workers.) . Humic substances–(plural) the collective name for the acid radicals found in humic matter. Typically separated from humic matter by alkaline extraction. […]

Humic Acid’s Role in Fertilization

Humic acid is technically not a fertilizer, although in some walks people do consider it that. Humic acid is an effective agent to use as a complement to synthetic or organic fertilizers. In many instances, regular humic acid use will reduce the need for fertilization due to the soil’s and plant’s ability to make better […]

How to extract soluble humate from leonardite?

“In order to be soluble, humates in raw form such as lignite or leonardite must go through an alkaline extraction process. Any of the salts like potassium hydroxide, sodium hydroxide or ammonium hydroxide can be used as the extractant. The potassium hydroxide extracted form is preferred for fertilizing application as potassium hydroxide (the extractant) is […]

How do fungi play a role in recycling nutrients on Earth?

Living things incorporate nutrients into their bodies. For example, plants absorb carbon dioxide from the air and water from the soil, then, using energy from the sun, synthesize carbon and hydrogen into carbohydrates. When you eat food, you break that food down into its basic units, and then reassemble those to build things like muscle. […]

Fulvic Acid

Fulvic acid is found in a liquid form along with mineral colloids。 Fulvic acids are poly-electrolytes and are unique colloids that diffuse easily through membranes whereas all other colloids do not. Fulvic acid supplements consisting of a neutral pH are very weak fulvic compounds and do not deliver the benefits of free form fulvic acid (fulvic […]
