Why do other people’s crops always grow stronger when grown on the same land? The secret might be using this “breathable” fertilizer—Amino Acid Fertilizer
Technical supporter: Amy Zhi
1.1 What is amino acid fertilizer?
Amino acid fertilizer is an organic fertilizer, it is not the normal chemical fertilizer, it is made from proteins broken down into their smallest units—amino acids which can be absorbed by crops directly. These amino acids do not require complex transformations and can directly penetrate the cell membranes of crop root, being quickly absorbed and providing directly nutrition. When crops show symptoms such as yellow leaves or week seedlings, amino acid fertilizer can quickly replenish core nutrients such nitrogen and carbon, like giving a sick crop a shot of adrenaline.
Besides providing nutrients, amino acids can also activate crop resistant, when faced with high temperatures and drought, amino acids can regulate the osmotic pressure with crop cells, locking in moisture and keeping the leaves upright, when a cold wave strikes, it promotes the synthesis of antifreeze substances such as proline, acting like a protective layer of crops.
Even more noteworthy is that amino acid fertilizers are also the guardians of the soil. Long-term use of chemical fertilizer can lead to soil PH imbalance, compacting and hardening. Amino acid, on the other hand, can chelate heavy metal ions in the soil, reducing their toxicity. Furthermore, as excellent food for microorganisms, they can rapidly proliferate benefits bacteria such as Bacillus subtilis and actinomycetes. These soil guardians decompose organic matter, loosen the soil structure, and keep the land youthful with each planting.
Amino acid fertilizers ensure that every drop of nutrition is utilized, and they can be precisely tailored to various crops, including field crops, cash crops, fruits, and vegetables.
2.1 How amino acids are made?
Currently, there are two main production process, which directly determine the quality and the effectiveness of the product.
2.1.1 Hydrolysis method (also called acid hydrolysis method)
This is a relatively traditional technique. The process as follow:
2.1.1.1 Hydrolysis:
Hydrochloric acid is added to protein raw materials—such as soybean meal from plants or animal hair—to break them down into amino acids under high temperature and pressure.
2.1.1.2 Neutralization and Separation:
After hydrolysis, the hydrolysate is neutralized with liquid ammonia (NH₃·H₂O) to a pH of 5.5–6.5. Unreacted residues (such as ash) are removed using a filter press, yielding a mixed amino acid solution.
2.1.1.3 Drying and Shaping:
Depending on the target product, if it is liquid fertilizer, it is directly filtered and filled; if it is solid fertilizer, it is made into powder through a spray drying tower or low-temperature drying equipment, and then packaged.
2.1.2 Enzymatic Hydrolysis (Also called Bio-enzymatic Hydrolysis)
This is the more advanced and mainstream process currently available, and it is the core technology behind our high-quality products. It mimics the natural process of biological decomposition, using specific enzymes—like precision scissors—to gradually “cut” protein raw materials into small-molecule amino acids and peptides under mild conditions.
2.1.2.1 Raw Material Pretreatment
Plant-based raw materials such as soybean meal, cottonseed meal, and corn flour are used. Water is added to prepare a slurry, which is then sterilized.
2.1.2.2 Enzymatic Hydrolysis and Fermentation
Amylase is first added to convert the starch into fermentable sugars, followed by the inoculation of other microbial strains for aerobic fermentation.
2.1.2.3 Purification and Compounding (If Applicable)
The fermentation broth is subjected to centrifugation or membrane filtration to remove microbial residues. It is then decolorized with activated carbon, concentrated, and finally compounded with nutrients.
2.1.2.4 Drying and Shaping:
Depending on the target product, if it is liquid fertilizer, it is directly filtered and filled; if it is solid fertilizer, it is made into powder through a spray drying tower or low-temperature drying equipment, and then packaged.
Excellent Safety: Contains no chloride, making it safe for all crops, including chloride-sensitive crops such as tobacco, potato, and grape.
Superior Efficacy: Delivers more pronounced effects in root development, stress resistance, color enhancement, and sugar content improvement.
3.1 What do amino acid fertilizers look like? — Product Forms and Content
The amino acid fertilizers we see on the market mainly come in three forms, each with its own characteristics.
3.1.1 Powder amino acid fertilizer
This is the most classic, economical and 100% water soluble amino acids. It is convenient to transport, has a long shelf life, and can be made with very high content.
3.1.1.1 How to interpret the content of amino acid fertilizer:
The 30% powder amino acid, 40% powder amino acid, 45% powder amino acid… up to 80% amino acid powder and 90% powder amino acid that we often talk about refer to the total amino acid content.
3.1.1.2 How to use powder amino acid fertilizer:
It needs to be dissolved in water before fertigation, drip irrigation, or foliar spraying. Solubility is crucial; good powdered fertilizers dissolve quickly and leave no residue.
3.1.1.3 Best sell products— powder amino acid fertilizer:
Our amino acid powder 30%，free amino acid 45%，hydrolysis of amino acid powder 80% or enzymatic amino acid powder 80 are consistently top-selling “trump cards.”
In 2025, we also launched 60% powder amino acid, 70% powder amino acid and 90% powder amino acid. The 60 and 70% powders fill the gap in the mid-to-high-end market, while the 90% powder represents the current “ceiling” content, specifically targeting high-end growers with the highest quality requirements.
3.1.2 Liquid amino acid fertilizer
Liquid amino acid fertilizers are currently a favorite because they are easy to use, require no stirring, and can be poured directly into fertilizer tanks or sprayers. They also typically have good compatibility and can be used with other water-soluble fertilizers and pesticides.
3.1.2.1 How to interpret the content:
Liquid fertilizer amino acid 30% free chloride , liquid fertilizer amino acid 50%, and liquid fertilizer amino acid 80% refer to the amino acid content. However, note that because liquids contain water, for the same content, their effects are faster and gentler than powders.
3.1.2.2 How to use liquid amino acid fertilizer:
Suitable for fertigation, drip irrigation, and foliar spraying; extremely convenient.
3.1.2.3 Our most popular amino acid fertilizer:
Liquid amino acids 30% free chloride :
Uses purer raw materials, ensuring high safety. Suitable for all crops, especially chlorine-sensitive cash crops (such as grapes, tobacco, and potatoes), providing peace of mind for many fruit and vegetable growers.
Enzymatic amino acid liquids 50%:
This is our flagship liquid product. Utilizing a fully enzymatic hydrolysis process, it boasts the highest small molecule activity. Used during critical growth stages (such as after transplanting, before flowering, and early fruit enlargement), it delivers immediate results, with particularly positive customer feedback on root development, seedling strengthening, low-temperature resistance, and flower bud promotion.
3.1.3 Amino acid granule:
This product was launched to meet the “hassle-free” needs of some customers. It’s essentially powder compressed into tablets through a specific process. Dosing is incredibly convenient; the amount of water to mix with each tablet is fixed, making it especially suitable for balcony gardening, small-scale planting, or beginners unfamiliar with dosages. The packaging is small and easy to carry.
4.1 What are the positive effects of amino acid fertilizers on plant growth?
After all that, what everyone’s most concerned about is: how exactly will using this make a difference to my crops?
4.1.1 Stronger Roots and Seedlings, No Transplanting Stress:
Amino acids stimulate root growth. After use, the root system is well-developed with more white roots, resulting in a high transplant survival rate and almost no slow-transplanting period. Our Enzymatic amino acid liquids 50% performs particularly well in this regard.
4.1.2 Improved stress resistance, reduced disease incidence, enhanced tolerance to continuous cropping:
Just like how vitamins make people less susceptible to colds, amino acids strengthen plant cell walls, improving their resistance to drought, cold, waterlogging, and pests. A single application before a late spring frost will yield visible results.
4.1.3 Improved Quality and Yield, Better Appearance:
This is the most crucial benefit. Amino acids promote photosynthesis, resulting in thick, dark green leaves; they also promote nutrient transfer to the fruit, resulting in even coloring, uniform size, high sugar content, and excellent taste.
4.1.4 Improve fertilizer utilization:
Amino acids themselves are chelating agents, acting like a “little helper” to “capture” nitrogen, phosphorus, potassium, and trace elements in the soil and deliver them to the plants.
People always asked: “Which amino acid fertilizer is best?”, Actually, there is no absolute ‘best’ among amino acid fertilizers, only the ‘most suitable’—the one that matches your crop is the good one
