Compound Fertilizer 17-17-17 (Sulfur Based) Guarantee Quality And Quantity

• Core Summary

NPK 17-17-17 is a high-concentration and balanced ternary compound fertilizer. Among them, "17-17-17" indicates that in this fertilizer:

The nitrogen (N) content is 17% 

The phosphorus (P₂O₅) content is 17% 

The potassium (K₂O) content is 17% 

The total nutrient content is ≥ 51%

• Characteristics and Advantages

• Balanced nutrition

• The three 17% ratios mean a balanced nutrient ratio (1:1:1), without any emphasis on a single element. This makes it a "universal" or "basic" fertilizer, suitable for a variety of crops and growth stages.

• High concentration and high efficiency

• The total nutrients exceed 51%, making it a high-concentration compound fertilizer. It has a high fertilizer efficiency per unit weight, takes effect quickly after application, is conducive to crop absorption, and can reduce transportation and application costs.

• Good physical properties

• It is usually granular, uniform in size, has good fluidity, is not prone to caking, and is convenient for mechanical application and manual broadcasting. It has good solubility and can be used as both base fertilizer and top dressing.

• Synergistic promoting effect

• The combined effect of nitrogen, phosphorus and potassium can comprehensively promote the vegetative growth (stems and leaves), reproductive growth (flowering and fruiting) and stress resistance (lodging resistance, disease and pest resistance) of crops.

• The main functions of each element

· Nitrogen (N) -17% 

· Function: It is an important component of proteins and chlorophyll. It mainly promotes the growth of stems and leaves, making the branches and leaves of crops lush and the color dark green, and is the core driving force for the vegetative growth of crops.

· Phosphorus (P₂O₅) -17% 

· Function: Promotes root development, flower bud differentiation and flowering and fruiting. It can enhance the cold and drought resistance of crops and promote the plumpness of grains.

· Potassium (K₂O) -17% 

· Function: It is known as a "quality element". It can promote photosynthesis and enhance the crop's resistance to lodging, diseases and pests. It plays an important role in improving fruit quality (such as enhancing sweetness, coloring, and improving storability).

• Applicable crops and periods

• Applicable crops:

· Field crops: rice, wheat, corn, cotton, etc., can be used as base fertilizer or top dressing during key growth periods. 

· Cash crops: tobacco, sugarcane, tea, etc. 

· Vegetables: Tomatoes, peppers, cucumbers, leafy vegetables and the vast majority of other vegetables. 

· Fruit trees: Apples, citrus fruits, grapes, pears, peaches, etc., have good effects when used in the early growth stage and fruit retention period. 

· Flowers and garden plants: Provide comprehensive nutrition for flowers and green plants.

• Notes

• It is not suitable to be used as a special fertilizer for the later stage: For crops mainly harvested for fruits or grains, more phosphorus and potassium are needed in the later growth stage. Continuing to use 17-17-17 at this time may cause excessive nitrogen, leading to late ripening and excessive greenness, which will affect the yield and quality.

• The dosage should be reasonable: Due to its high concentration, the dosage should be determined based on soil fertility, crop type and target yield to avoid excessive application causing fertilizer damage and environmental pollution. Please follow the product manual or the guidance of local agricultural technicians.

• Supplementing trace elements: NPK 17-17-17 only provides macronutrients. Long-term use may lead to deficiencies of trace elements such as calcium, magnesium, sulfur, boron, and zinc in the soil. It should be noted that supplementation can be achieved by applying organic fertilizers or corresponding micro-fertilizers.

• Keep a distance from seeds/root systems: When used as seed fertilizer or applied during the seedling stage, avoid direct contact between the fertilizer and the seeds or the root systems of seedlings to prevent "burning the seedlings".

• Summary

• NPK 17-17-17 is an excellent "all-round" base fertilizer. It is like a balanced "main meal" prepared for plants, which can meet the basic needs of most crops for nitrogen, phosphorus and potassium during their critical growth periods. For ordinary growers, if they are not sure what formula of fertilizer to use, choosing 17-17-17 usually won't make a big mistake.
