THREE MAJOR BIOSTIMULANTS: Humic Acid, Alginic Acid, and Amino Acid

THREE MAJOR BIOSTIMULANTS: Humic Acid, Alginic Acid, and Amino Acid

Biostimulants, also termed plant conditioners or bioeffectors, are substances, cultures of micro-organisms, and mixtures of materials used to promote the growth of crop plants and can include natural or artificial plant growth regulators and biofertilizers.

Biostimulants are new types of fertilizers. Compared with traditional fertilizers, they are more advanced. They can directly or indirectly provide nutrients to crops. At the same time, they also have the functions of maintaining moisture, resisting drought, resisting cold, and killing insects; they control nitrogen, and active phosphorus, promote potassium, can chelate medium and trace elements in the soil, and improve fertilizer utilization.

The world’s recognized plant biostimulant products are divided into 4 categories from the source: Mineral source, Marine source, Microbial source, and plant source. The most common biostimulants on the market are Humic Acid, Alginic Acid, and Amino Acid.

So what are the differences between these three acids?

1. Humic acid – mineral source
The humic acid main substance of New-Nutri Potassium Humate (OMRI listed), is a natural organic macromolecular weak acid extracted from leonardite. It can adhere to the surface of minerals such as sand, retain water and fertilizer after application, and promote soil improvement. It is especially suitable for barren soils such as sand and loess.
Humic acid contains 90% carbohydrates, which the main component is glucose, it will make the fruit sweeter; it will also increase the proportion of carbon in the crop, thus increasing the weight of the fruit.
Humic acid mainly plays a long-term conditioning effect, regulating soil and promoting crop growth.

2. Alginic acid – marine source
Alginic acid, the main substance of New-Nutri Seaweed extract (OMRI listed), exists in ascoppyllum nodosum and kelp. It greatly retains the natural active ingredients of seaweed and is a new type of fertilizer with high efficiency and low cost.
Alginic acid is a natural polysaccharide. Under normal conditions, it exists in the cytoplasm and can play a role in strengthening the cell wall, thereby fully regulating the physiological functions of plants, promoting crop metabolism, improving the efficiency of photosynthesis, and promoting crop growth.
Alginic acid contains a variety of marine active ingredients and a variety of nutrients, which can fully regulate the physiological functions of crops, greatly increase the permeability and conduction capacity of leaves, and are more conducive to the absorption of nutrients by crops.
Alginic acid, as a powerful crop stimulating factor, enhances the cold resistance, drought resistance, and other stress resistance of crops by regulating the signal pathway dependent on ABA (abscisic acid).
Alginic acid mainly promotes crop growth and enhances the cold resistance and drought resistance of crops.

3. Amino Acids – Plant Source
Amino acids are small molecule organic nutrients converted in an organic form from plant or animal proteins. They can be directly absorbed by crops and are organic nitrogen sources. After using them, the leaves of crops become larger, greener, and thicker; the fruits also become larger; the taste is increased; the quality is improved; the resistance of crops is improved, and the soil can also be improved.
After multiple experiments on various crops, it has been shown that New-Nutri Amino Acid (OMRI listed) can indeed significantly increase crop yields, and can effectively increase the soluble sugar content of the product, reduce the NO3- content, and improve the absorption and utilization of nitrogen, phosphorus, and potassium.
Amino acids mainly provide nutrition for crop growth and improve crop resistance.

These are the differences between these three acids as above, they can be used at the same time and complement each other to maximize fertilizer utilization.
