Synergistic application of corn steep liquor powder and amino acid powder in the field of agricultural fertilizers

Corn steep liquor powder has a cost advantage and more comprehensive nutrition than amino acid powder. The two can form a synergistic effect in the application of agricultural fertilizers through nutritional complementarity, fertilizer efficiency enhancement and cost optimization, which can achieve the improvement of fertilization effect and optimization of economic benefits.

1: Nutritional complementarity, rich and comprehensive nutrition supply

Corn Steep Powder is a by-product of the initial processing stage of corn starch. It is made through processes such as concentration, impurity removal and spray drying, and retains the rich nutrients in Corn Steep Liquor. Its main ingredients include protein (≥43%), amino acids (≥35%), organic matter (about 60%), nitrogen, phosphorus and potassium (NPK 7-7-7), and natural hormone substances that promote plant growth, such as a variety of natural vitamins, organic growth factors and zeatin. It has the characteristics of good water solubility, comprehensive nutrition, and easy transportation and storage.

Amino acid powder is an important organic nitrogen source with a small molecular weight and can be directly absorbed by plants. It is rich in a variety of essential amino acids and can quickly supplement the nitrogen needs of crops. It can also be used as the core component of biostimulants to participate in activating the plant immune system.

However, amino acid powder (14-0-0) has a single nutrient and cannot be used as the main nutrient source for crops. It must be used in conjunction with basic fertilizers.

Synergistic effect

Combination of fast-acting and slow-acting: amino acid powder provides fast-acting nutrients, and Corn Steep Liquor (CSL) Powder provides slow-acting organic matter, achieving continuous nutrient release to meet the needs of crops throughout the growth period.

Balancing nutritional shortcomings: Corn Steep Powder (CSP) supplements the phosphorus, potassium and trace elements lacking in amino acid powder, and amino acid powder increases the types and content of amino acids in fertilizers, avoiding excess or deficiency of a single nutrient, and meeting the diverse nutritional needs of plants.

2. Fertilizer efficiency enhancement: improving fertilizer application efficiency

1: Promoting microbial activity

Corn Steep Liquor Dry Powder: as a culture medium for microbial fertilizers (such as Bacillus subtilis and phosphate-solubilizing bacteria), it provides carbon and nitrogen sources and promotes the expansion of bacterial species. Experiments show that adding dried Corn Steep Liquor (CSL) can significantly increase the number of live Bacillus.

Amino acid powder: balancing microbial nutritional needs, accelerating microbial metabolism, and improving fermentation efficiency.

Synergistic effect: The combination of the two can shorten the composting cycle, improve the efficiency of organic fertilizer decomposition, enhance the bacterial activity of biological fertilizers, promote the mass reproduction and growth of microorganisms, and improve the nitrogen fixation and phosphorus solubilization capabilities of fertilizers.

2: Improve soil environment

dried Corn Steep Liquor: absorbs heavy metal ions through organic matter to reduce their toxicity; its acidic pH (4.5) can adjust alkaline soil.

Amino acid powder: small molecule amino acids can chelate calcium, magnesium and other elements in the soil to improve nutrient utilization.

Synergistic effect: CSL powder can increase the organic matter content of soil, improve soil structure, and enhance the soil's ability to retain water and fertilizer; amino acid powder optimizes nutrient form, jointly promotes crop root development, and enhances stress resistance.

3: Improve crop quality

Corn Steep Liquor CSL Powder: contains 35% amino acids, multiple B vitamins and natural growth factors, which can stimulate crop growth and increase yields.

Amino acid powder: glycine can increase photosynthetic intensity and promote enzyme activity; cystine and tyrosine can improve the color and taste of vegetables and fruits.

Synergistic effect: The combination of the two can increase the types and contents of amino acids in fertilizers that are easy for plants to absorb, thereby significantly improving the protein content, vitamin content and flavor quality of crops. It can be used during the flower and fruit preservation period of fruits and vegetables to increase yields.

3. Cost optimization: reducing fertilizer production costs

In foliar fertilizer applications, corn steep liquor powder can partially replace amino acid powder to reduce costs while ensuring effects;

In the production process of bacterial fertilizers, corn steep powder can replace 20%~40% of yeast powder and peptone to reduce the cost of microbial fertilizer culture media;

In chemical compound fertilizers, Corn Steep Liquor Dry Powder can be used as an organic carrier to reduce fertilizer loss, improve utilization rate, and improve soil structure.

Corn Steep powder and amino acid powder each have unique advantages and application values. Through partial substitution and synergistic effects, they can significantly improve fertilizer performance and crop yields and significantly reduce costs. Achieve a win-win situation of fertilization effect and economic benefits.
