NPK stands for nitrogen, phosphorous and potassium, the three major macronutrients plants need, so most fertilizers or plant foods list the NPK fertilizer ratio on the bag. For example,Corn steep liquor powder（CSL powder）contains Organic NPK 7-6-6, it means that the fertilizer contains 7% nitrogen, 6% phosphorus, and 6% potassium.Spray Dried Corn Steep is a water-soluble organic fertilizer raw material that derived from non-GMO Corn, by product of corn wet milling process. Corn Steep Liquor Dry Powder contains not only NPK, but also Amino Acid and active peptides 35%,Organic matter 60%,Carbohydrate 31%,Trace elements and other growth promoting factors.

Why Is NPK Important?

Nitrogen is considered to be the most important nutrient, and plants absorb more nitrogen than any other elements. Nitrogen is essential to ensure plants are healthy as they develop and nutritious to eat after they’re harvested. That’s because nitrogen is essential in the formation of protein, which make up most of the tissues of most living things..

It is worth mentioning that, Nitrogen (N) is critical to the the process of photosynthesis. It is the building block for growing new stems and leaves, plus it is a necessary part of chlorophyll, which makes the leaves green and helps plants with photosynthesis..

 Below is a picture of corn that is nitrogen deficient. Low nitrogen (N): Pale green or yellowing older leaves, undersized leaves, or short or weak stems.

The second of the Big 3, phosphorus, is linked to a plant’s ability to use and store energy, including the process of photosynthesis. It’s also needed to help plants grow and develop normally, phosphorous is needed for the growth of plant roots, fruits and flowers.A lack of phosphorus in crop soil will produce weak plants that are prone to wilting, discoloration, and inadequate fruit.

Below is a picture of corn that is phosphorus deficient. Low phosphorus (P): Red or purple tinges to leaves that are supposed to be green, or leaves with twisted or irregular shapes.

Potassium is the third key nutrient of fertilizers. It helps to enhance the disease resistance of plants and plays an important role in increasing crop yields and overall quality. Potassium also protects the plants when the weather is cold or dry, strengthens their roots and prevents wilting.

Below is a picture of corn that is potassium deficient.Low potassium (K): Lower leaves that are dead at the edges or in spots, or are wilting.

Thus, NPK ratio is an important indicator to find the best fertilizer. Corn Steep Liquor Powder(NPK 7-6-6) is a competitive organic fertilizer raw material.

1,Used as one stand alone water soluble organic fertilizer. Foliar：2g --5g /L water 0.2kg--2kg/ha When mixing,fill spray tank half full with water and add the required amount of CSL powder while continuing to fill tank water. Also you can add fish emulsion as spray oil or surfactant.Via Irrigation :5-100kg/ha.

2,Use Pure Organic Corn Steep Liquor Powder as carrier for microbes. Spray Drying Corn Steep Liquor not only to feed beneficial microbes but also supply readily available nutrients for crops.

Dissolve Maize steep liquor powder in water and mix with microbes in fermented tank. After a period of fermentation,more nutrients in CSL powder are converted smaller molecules which can be absorbed by crops directly;

Mix microbes with Corn steep liquor powder（CSL powder）in solid directly. The beneficial bacteria, fungi and mycorrhizae and a mixture of readily available amino chelated micronutrients that work to promote heal thy soil, and healthy roots and plants.

3,Used as one organic input blend with humic acid,sea kelp extract,amino acid powder or other ingredients. Corn steep liquor powder may be used successfully on most crops.
