Corn steep liquor dry powder has a balanced ratio of NPK 7-7-7 and is 100% soluble in water. It is rich in up to 60% organic matter, which can transport a large amount of carbon source to the soil and effectively improve the physical and chemical properties of the soil. The protein content of Corn Steep Powder is not less than 42%, and the total amino acid content is not less than 35%. These nutrients can be directly absorbed and utilized by crops, providing sufficient nitrogen source guarantee for the growth of tomatoes.
1. Corn steep liquor powder significantly promotes tomato growth
Corn steep liquor dry powder has a balanced ratio of NPK 7-7-7 and is 100% soluble in water. It is rich in up to 60% organic matter, which can transport a large amount of carbon source to the soil and effectively improve the physical and chemical properties of the soil. The protein content of Corn Steep Powder is not less than 42%, and the total amino acid content is not less than 35%. These nutrients can be directly absorbed and utilized by crops, providing sufficient nitrogen source guarantee for the growth of tomatoes.
In addition, Corn Steep Liquor (CSL) Powder also contains a variety of biologically active substances such as vitamins, cell growth factors, active peptides, and inorganic elements such as phosphorus, potassium, and magnesium. Its ash contains inorganic elements such as K, Mg, Ca, P, and Fe, which can provide all-round and comprehensive nutritional support for tomato growth.
2: Advantages of Corn Steep Powder (CSP) as an organic fertilizer for tomato planting
The application of organic fertilizers such as Corn Steep Liquor Dry Powder can significantly improve the nutritional quality and taste of tomatoes. Specifically, it can increase the content of soluble sugar, soluble protein and VC in the fruit, optimize the sugar-acid ratio, increase the content of lycopene, and thus improve the overall flavor of the fruit.
According to the research results of the National Research Institute of Vegetables, Ornamental Plant and Tea (NIVOT) in Japan (1), when Corn Steep Liquor is applied at an appropriate concentration, Corn steep water alone can fully meet the initial growth needs of tomatoes without causing adverse conditions such as nitrogen deficiency. However, it should be noted that the calcium content of dried Corn Steep Liquor is relatively low. It is usually recommended to mix it with calcium-rich additives such as oyster shells and bone meal and corn syrup powder to fully meet the nutritional needs of tomato growth.
Experiments have shown that Corn Steep Liquor (CSL) Powder as an organic liquid fertilizer has a significant promoting effect on the initial growth and rhizosphere environment of tomato seedlings. When Corn Steep Liquor Solids is applied at an appropriate concentration, the growth of tomato plants is good, and the aboveground weight can reach about 80% of that in the inorganic liquid fertilizer treatment area, while the root weight is similar to that in the inorganic liquid fertilizer treatment area. This fully demonstrates that corn steep liquid can meet the basic nutrient needs of tomato growth.
Secondly, Corn Steep Liquor has a positive effect on the development of tomato roots, especially promoting the growth of surface roots. Compared with the experimental group that applied full-layer basal fertilizer, the tomato root distribution in the experimental group treated with liquid fertilizer was shallower, and the amount of surface roots increased significantly, thereby improving the absorption efficiency of tomato plants for water in the surface soil. In addition, the tomato root system applied with Corn Steep Liquor was thicker, which helped to enhance the absorption capacity and transportation efficiency of the root system, and improve the stability and stress resistance of the plant.
The application of Maize steep liquor also helps to reduce the residual inorganic ion content in the soil, effectively prevent the accumulation of soil salt, and improve the soil environment. At the same time, the organic matter in corn steep liquid powder gradually decomposes in the soil, providing a continuous and stable nutrient supply to the soil, activating the activity of soil microorganisms, and further optimizing the rhizosphere environment.
In summary, corn steep powder, as an organic liquid fertilizer, has shown excellent performance in promoting the growth of tomato seedlings, optimizing root structure, improving water and nutrient absorption efficiency, and improving soil environment. It is an organic fertilizer with great application potential.

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.
Corn Steep Liquor Powder: The "Nutritional Engine" in Industrial Fermentation
In the fields of bio-pharmaceuticals, amino acid production, and enzyme preparation production within industrial fermentation, the quality of fermentation media raw materials directly impacts the production efficiency and product quality of microbial fermentation. As a practitioner in the industrial fermentation sector, are you searching for a high-quality fermentation raw material that can enhance production efficiency, reduce costs, and improve product quality? Corn Steep Liquor (CSL) powder is your optimal choice.
Corn Steep Liquor Powder: A New Choice for Organic Agricultural Fertilizers
Selecting an efficient and eco-friendly organic fertilizer is crucial for enhancing soil quality and promoting crop growth. Corn Steep Liquor (CSL) powder emerges as a novel option in the realm of organic agricultural fertilizers.
What are the benefits of applying amino acid powder(NPK 14-0-0) to plants?
Amino acid powder can provide organic nitrogen, and plants can directly absorb and utilize the amino acids in the amino acid powder through roots or leaves, making it easier to produce protein and saving the energy required to produce amino acids.
Corn steep liquor powder: Cost-effective Feed Additive
Corn steep liquor powder can be used as a feed protein source or as food for beneficial microorganisms in feed fermentation (fermentation medium), promoting the growth of beneficial microorganisms, thereby improving the nutritional utilization of feed, reducing feed costs, and improving animal growth performance; it is widely used in feed additives for ruminants, chickens, aquatic feed, etc.
