Fulvic Acid

Fulvic acid is the most plant-active of the humic acid compounds. It’s a plant growth stimulator that normally contains a very broad spectrum of bioavailable nutrients such as: vitamins, up to 72 minerals, fatty acids, hormones, ketones, phenols and flavonoids–making it one of the most chemically active compounds in nature, hence increases plant metabolism and nutrient intake. It is naturally created in soil by composting and can rejuvenate soil. Fulvic acid is an excellent supplement to fertilizers to improve nutrient absorption.

Generally, low-molecular-weight substances are 100% permeable to cell membranes, and high-molecular-weight substances are not. Fulvic acid, in conjunction with water, is very low-molecular-weight and thus in its pure form 100% absorbable to living cells. Furthermore, fulvic acid lowers the surface tension of water allowing the water to penetrate other ORGANIC molecules better, and has been shown to increase solubility of otherwise insoluble organic materials at least 20 times greater than water alone. Fulvic acids can ‘fix’ high-molecular-weight ORGANIC compounds and cause them to become water soluble. Fulvic acid also has the ability, over time, to chelate inorganic elements, metals and other inorganic compounds and turn them into organic molecules thus making them soluble, low- molecular-weight, and absorbable.

Fulvic acid has multiple benefits including:

1) Improving the uptake of nutrients by plants in foliar and soil applications
How …. Because of the relatively small size of fulvic acid molecules, they readily enter plant roots, stems and leaves. They carry trace minerals and nutrients from plant surfaces into plant tissues. Fulvic acids are the most effective carbon containing chelating compounds known with a CEC of 1400 meq/100g (which is a result of more caboxyl groups – COOH, and about twice CEC of humic acid). (Yazdani 2014)

2) Easy to use effective chelating agent
Chelates All Monovalent & Divalent Elements to which it is exposed …
Fulvic acid has the power to form stable water soluble complexes with monovalent, divalent, trivalent, and polyvalent metal ions. It can aid the actual movement of metal ions that are normally difficult to mobilize or transport. Fulvic acids are excellent natural chelators and cation exchangers, and are vitally important in the nutrition of cells.

Effective chelating agent across a wide pH range …
How …. Fulvic acids are a biologically active mixture of weak organic acids which are soluble in water at all pH conditions.

3) Offers drought protection due to improved water storage
How …. Multiple mechanisms including higher water and chlorophyll content in plants and enhanced antioxidant enzyme activities that destroy ROS (reactive oxygen species toxicity). (Lofti 2015, Xudan 1989)

4) Bonds with plant nutrients to reduce their immobilisation in the soil.
How …. High CEC holds nutrients and makes them plant available.

5) Fulvates also:
• Promote quicker seed germination and faster root and shoot growth
• Provide a valuable source of active carbon for soil micro-organisms
• Buffer UAN foliar sprays
• Improve the efficacy of many non-selective herbicides

FULVATES – VALUABLE EXTRAS!
Due to their diverse functional groups fulvates have a lot more to offer including improved growth, enzyme activity and disease reduction. In research by Kamel 2014 on cucumbers, 150ppm fulvic significantly increased growth parameters including plant height, leaf number, yield. FA increased activity of soil microorganisms, the enzymes dehydrogenase and nitrogenase and chlorophyll content in fresh plants. FA also reduced downy mildew and powdery mildew disease.
How …. As fulvic acid molecules are relatively small they readily enter plant roots, stems and leaves and carry trace minerals and nutrients from plant surfaces into plant tissues. Increasing the plant growth processes within the leaves increases the carbohydrate content of the leaves and stems. These carbohydrates are transported down the stems into the roots where they are released as root exudates to provide nutrients for soil microorganisms. The microorganisms in turn release acids and other organic compounds to increase the availability of plant nutrients plus microbes outcompete pathogenic soil microbes and reduce disease.

1、抗病功能

土壤有机质含量高，为有益微生物提供一个优良的环境，有益种群逐步发展有为优势种群抑制有害病菌的生长，再加上植物本身由于土壤条件优良而生长健壮，抗病能力加强，因而大大减少病害，特别是土传病害的发生。

2、改良土壤

形成胶状物质腐肥中的黄腐酸或黄腐酸钾或有机胶体在土壤中形成胶状物质，能把土粒胶结起来，使土壤中水稳性团粒增加，协调土壤的水、肥、气、热状况，对改良过砂过黏等贫瘠土壤效果很好，从而改善作物的生态环境。黄腐酸钾在改良盐碱土壤中,以其含有活性基因较多，盐基交换容量大，能够使壤的可溶性盐中吸附和阻留较大数量的有害阳离子，降低土壤盐浓度,降低盐碱土的酸碱度。从而改善作物的生态环境。

3、能增强作物的抗逆性能
