The best organic fertilizers come from natural sources, such as corn steep liquor powder,rather than relying on synthetic nutrients produced in chemical plants (sometimes from petroleum-based feedstocks). Great organic fertilizer options are available both as granulated solids that can be spread on top of garden soil, or as water-soluble powders or concentrates that are diluted with water and poured or sprayed onto the soil. OMRI (Organic Materials Review Institute) has listed many of the best options that can be safely used in agriculture.

1,Corn Steep Liquor Powder (Organic NPK 7-6-6)

Corn steep liquor powder（CSL powder）is a water-soluble organic fertilizer powder that derived from non-GMO corn, by product of corn wet milling process. It is a non - adhesion, non - caking, very fine yellow powder,which OMRI listed and Ecocert approved. This fertilizer has an pH of 4.5.

It contains Organic NPK 7-6-6,Amino Acid and active peptides 35%,Organic matter 60%,Carbohydrate 31%,Trace elements and other growth promoting factors. It is worth mentioning that the protein content of CSL powder is higher than that of similar products：the protein content is more than 42.2%,up to 50%.

Corn steep liquor powder can be applied directly, or it can be mixed with other liquid fertilizers, growth promoters (seaweed) or dry fertilizer, whether it is sprayed,irrigated,foliar or applied through soil.It is suitable for most plants.

CSL powder has many positive effects as an organic fertilizer raw materials.

It can provide the nutrients needed for crop growth,and it helps to build root system,enhance nutrient uptake and promote the natural growth of plants with nitrogen, phosphorous and potassium. it also contains micronutrients such as iron, sulfur and manganese, as well as amino acids, which are completely non-toxic, harmless and pollution-free.

Corn steep liquor powder has other effects as well.For example, it can also improve the structure and fertility of the soil, promote the activities of microorganisms and soil organisms, and contribute to higher yield and quality.

2,Rock phosphate fertilizer

Rock phosphate is made from ground rocks. It contains high amounts of phosphate and other essential nutrients. The biggest advantage of using this kind of fertilizer is that the elements it contains do not dissolve in water. In this way,they hang around in the soil until they’re used by the plants that are growing there.

3,Blood Meal fertilizer

This fertilizer is made from the blood meal of butchered livestock. While it is high in nitrogen, blood meal is low in other elements. It is highly acidic,and may burn plants if used too much at once,so it should be used with some caution.

It is best to apply blood meal to the soil before planting anything.

4,Fish emulsion fertilizer

Fish emulsion fertilizer is high in nitrogen but has no calcium or potassium. The acid is very strong, should be careful to use in order to avoid burning plants. However, once applied, it works immediately and is a good way to increase the organic material of the plant for leafy species with low nitrogen content. It should be noted that some plants may not tolerate it very well.

5,Liquid Kelp Fertilizer

This is a liquid seaweed fertilizer made through cold processing. Kelp contains a small amount of the main three fertilizer components but it’s quite high in trace elements. It is also a good source of growth hormones, which can help plants reach their full potential by supporting root development. This liquid fertilizer is typically mixed with water and used as a foliar spray or into the plant in the surrounding soil.
