Amino acid liquid fertilizer anti-corrosion and anti-odor solution: Solving the problems of bulging barrels and odor generation at the source
The amino acid liquid fertilizer is rich in free amino acids, peptides, active proteins and other organic nutrients, and is a core fertilizer category for improving agricultural productivity in modern agriculture. However, its high organic matter and high moisture content characteristics naturally make it a breeding ground for bacteria, molds, and yeast. The decomposition of amino acids by microorganisms mainly involves deamination and dehydrogenation reactions - Escherichia coli, Proteus, Bacillus subtilis, etc. break down cysteine to produce acetic acid, ammonia gas and hydrogen sulfide; tryptophan is decomposed to produce indole, acetic acid and ammonia gas. The final products are gases such as ammonia gas, carbon dioxide, and hydrogen sulfide, causing the product to swell, bubble, stink, and separate, resulting in nutrient loss, reduced fertilizer efficacy, and spoilage of the product, which may also cause root diseases in crops.
Dalian Tianwei has developed a dedicated composite anti-corrosion solution based on the characteristics of the amino acid liquid fertilizer system, with a targeted compound slow-release technology as the core, to achieve full-cycle microbial protection from the production end.
Why does amino acid liquid fertilizer deteriorate - Understanding the necessity of anti-corrosion from the root cause
Chemical pathways of amino acid decomposition by microorganisms
In amino acid aqueous solutions, microorganisms mainly decompose amino acids through two pathways:
Deamination: Microorganisms (such as Escherichia coli, Proteus, Bacillus subtilis, etc.) break down amino acids, generating ammonia gas, hydrogen sulfide, etc. Cysteine hydrolysis produces acetic acid, ammonia gas and hydrogen sulfide; tryptophan hydrolysis produces indole, acetic acid and ammonia gas.
Dehydrogenation: Primarily caused by spoilage bacteria and fungi, amino acids undergo dehydrogenation and generate reduced carbon atoms amines and carbon dioxide.
The results of these two reactions are the production of ammonia gas, carbon dioxide, and hydrogen sulfide, causing swelling, bubbling, and the generation of odorous substances such as amines, which seriously affect product quality and usage effects. Dalian Tianwei Chemical Co.,LTD anti-corrosion agent uses a targeted compound antibacterial system to inhibit these two decomposition pathways from the source, and at the same time degrades the odor substances already produced in the system.
Chain consequences of deterioration
Swelling and bulging of the container: Gas accumulation causes packaging deformation and damage, resulting in product scrapping and return loss.
Odor generation and stratification: Metabolic byproducts of spoilage cause unpleasant odors, the liquid becomes turbid, and blackens and precipitates, losing its commercial value.
Loss of fertilizer efficacy: Amino acids and peptides are decomposed and consumed by microorganisms, resulting in significant nutrient loss and reduced effectiveness when applied to the soil.
Root diseases: Harmful bacteria in deteriorated liquid fertilizer can cause root diseases in crops after being applied to the soil.
