17-23-5 Compound Fertilizer Original Manufacturer

Interpretation of the basic meaning

"NPK" is an abbreviation for the three main nutrients required by plants:

·N (nitrogen) : 17% - Promotes the growth of stems and leaves, making the branches and leaves of crops lush and the leaf color dark green.

·P₂O₅ (phosphorus) : 23% - Promotes root development, flower bud differentiation, flowering and fruiting, and enhances the cold and drought resistance of crops.

·K₂O (potassium) : 5% - Participates in photosynthesis, promotes the synthesis of carbohydrates and proteins, and enhances the ability to resist lodging and diseases and pests.

"Blended fertilizer", also known as BB fertilizer, is made by physically mixing three single or compound fertilizers of nitrogen, phosphorus and potassium in a specific formula ratio. Its feature is that the formula is flexible and can be "tailor-made" according to soil conditions and crop requirements.

Therefore, NPK 17-23-5 is a blended compound fertilizer with a high phosphorus, medium nitrogen and low potassium ratio, which is particularly focused on promoting the early root development and flowering and fruiting of crops.

Main features

· Outstanding high phosphorus content: With a phosphorus content of 23%, it is the most notable feature, which can strongly stimulate the growth of crop roots, promote their development, and lay a solid foundation for nutrient absorption in the later stage.

· Precise nutrient ratio: The ratio of 17-23-5 is highly suitable for use in the early growth stage of crops (such as the seedling stage and after transplanting) or in crops that are sensitive to phosphorus requirements.

· Physical mixing, cost controllable: As a blended fertilizer, its production process is relatively simple. The formula can be flexibly adjusted according to the local soil test results and target crops, avoiding nutrient waste and offering high cost performance.

· Promoting flowering and fruit retention: Adequate phosphorus can effectively promote flower bud differentiation, improve flowering quality and fruit setting rate.

Applicable crops and application period

This fertilizer is particularly suitable for use in the following situations:

Main application period:

· Base fertilizer: Applied during land preparation before sowing or transplanting, it provides basic phosphorus nutrition for the entire growth period of crops.

· Seedling topdressing: Applied in the early growth stage of crops (such as the tillering stage and after transplanting) to promote the robustness of seedlings and the penetration of root systems.

Particularly applicable crops:

· Food crops: such as wheat, corn, rice, etc., are used as seed fertilizer or base fertilizer when sowing to cultivate strong seedlings.

· Economic crops: such as cotton, rapeseed, peanuts, soybeans, etc., show remarkable effects when used in the seedling stage.

·For fruit trees such as apples, pears and citrus fruits, it can be applied before the buds sprout in spring or after flowering to promote the growth of new roots and flowering.

·Vegetables: Especially fruit vegetables (such as tomatoes, peppers, cucumbers) and root vegetables (such as radishes, potatoes), when used as base fertilizer during transplanting, can effectively increase the yield.

·Tobacco: It has a high demand for phosphorus, and this formula is very suitable.

Application method and precautions

Application method:

· Deep application of base fertilizer: It is recommended to evenly spread it during land preparation and then plough it into the soil to a depth of about 10 to 20 centimeters. Phosphorus has poor mobility in soil and can only be effectively absorbed when it is deeply applied to the root system layer.

· Row application or hole application: For row-sown crops, row application or hole application can be carried out to concentrate nutrients and improve utilization rate.

· Avoid direct contact with seeds: When used as seed fertilizer, keep a certain distance from the seeds (usually 5-7 centimeters) to prevent seed and seedling burning.

Notes

Fertilization based on soil conditions: This formula is particularly suitable for use in phosphorus-deficient soils such as red soil, yellow soil, and soils with strong acidity. If the soil itself is rich in phosphorus, using this formula may cause waste.

Fertilization based on crops: For crops that have a high demand for potassium in the middle and later stages of growth (such as watermelons, grapes, and sugarcane), the potassium provided by this fertilizer alone is insufficient. It is necessary to supplement high-potassium fertilizers in the later stage.

In combination with other fertilizers: For the best results, it is recommended to apply it in combination with organic fertilizers. According to the growth stage of the crops, apply high-nitrogen or high-potassium fertilizers in the middle and later stages to meet the nutritional needs of the crops throughout their growth period.

Specific dosage: Please be sure to refer to the instructions on the fertilizer packaging or determine the dosage per mu based on the soil testing and formula suggestions of the local agricultural technology extension department.

Summary

NPK 17-23-5 blended fertilizer is a high-phosphorus formula fertilizer with the core functions of "strengthening roots, promoting flowers and strengthening seedlings". It is an ideal nutrient supplier for the early growth stage of crops, effectively building a strong root system and laying a foundation for high and stable yields. When choosing, users should combine their soil conditions and crop types, and apply scientifically to achieve the maximum benefit.
