Long Lasting Fertilizer Effect 17-20-8Npk Compound Fertilizer with Twelve Elements

• NPK 17-20-8 compound fertilizer (marked as "12-element Fertilizer") is a high-phosphorus type compound fertilizer with multiple trace elements added. It not only provides the main nitrogen, phosphorus and potassium needed for crop growth, but also supplements key medium and trace elements, achieving a more comprehensive nutritional supply.

• Core ternary macronutrients NPK: 17-20-8

· Nitrogen (N) 17% : Provides basic nutrients, promotes the growth of stems and leaves, increases chlorophyll, and makes the plant lush. The content is moderate to avoid excessive growth during the critical period when phosphorus and potassium are needed. 

· Phosphorus (P₂O₅) 20% : This is the outstanding feature of this formula, with the highest content. Phosphorus can strongly promote root development, flower bud differentiation, flowering and fruiting, and plumpness of grains, and can also enhance the stress resistance of crops. 

· Potassium (K₂O) 8% : It helps with nutrient transportation, fruit enlargement, coloring and sweetening, improves crop quality and enhances resistance to lodging and diseases. The content is relatively balanced, supporting later growth.

Formula features: High phosphorus, moderate nitrogen, and potassium. It is highly suitable for use during the middle growth stage of crops when they need to shift from vegetative growth (growing branches and leaves) to reproductive growth (flowering and fruiting).

• What elements are usually included in the "Twelve Elements"?

In addition to the three macronutrients N, P and K, the fertilizer also scientifically adds the following nine elements, forming the "Twelve Elements"

Medium element:

Calcium (Ca) : Strengthens cell walls, prevents fruit cracking, and alleviates physiological diseases. 

Magnesium (Mg) : A core component of chlorophyll, it participates in photosynthesis. 

Sulfur (S) : Essential for the synthesis of proteins and vitamins, it improves quality.

Trace elements:

Iron (Fe), manganese (Mn), zinc (Zn), copper (Cu), boron (B), molybdenum (Mo) : Although the demand for these elements is extremely small, they are of vital importance. They act as catalysts for various enzymes and are involved in almost all physiological and biochemical processes of crops, such as pollination and fruit setting (boron), auxin synthesis (zinc), nitrogen fixation (molybdenum), etc.

• Main functions and advantages

· Promoting root growth and strengthening seedlings: High phosphorus content can greatly promote root development, making the crop's root system well-developed, enhancing absorption capacity, and ensuring uniform and strong seedlings. 

· Flower and fruit retention: When used before and after flowering, it can effectively promote flower bud formation, increase fruit setting rate, and reduce flower and fruit drop. 

· Comprehensive nutrition: It supplements multiple nutrients at one time to prevent and correct various physiological diseases caused by nutrient deficiency (such as small leaf disease, yellow leaf disease, umbilical rot, flower without fruit, etc.). 

· Enhance quality and resistance: A balanced supply of nutrients helps fruits expand, color evenly, and accumulate sugar, while also improving the crops' resistance to drought, cold, and diseases. 

· Simplify fertilization: Eliminate the trouble of purchasing and applying trace element fertilizers separately, and improve fertilization efficiency.

• Applicable crops and periods

• It is particularly suitable for: fruit trees (such as citrus fruits, apples, grapes, mangoes, etc.), solanaceous vegetables (tomatoes, peppers, eggplants), melons (watermelons, cantaloupes), root and tuber crops (potatoes, sweet potatoes), flowers and various cash crops.

• Optimal usage period
  

· Transplanting and setting period: As base fertilizer or root-fixing fertilizer, it promotes the recovery of seedlings and the establishment of root systems. 

· Pre-flowering period: Store energy for flowering. 

· Young fruit stage: Promote the development of young fruits and stabilize and strengthen them. It is not recommended as a top dressing in the later stage: Due to its high phosphorus content, if fruit expansion and coloring are needed in the later stage of crop growth, high-potassium fertilizers should be used instead.

• Precautions for use

· Application method: It can be used as base fertilizer (deep application), top dressing (furrow application or hole application, covering with soil). It is recommended to mix with soil and avoid direct contact with seeds or root systems. 

· Dosage control: Strictly follow the product instructions and local agricultural technical guidance. Do not exceed the dosage. Although trace elements are necessary, excessive amounts (especially boron and copper) may cause poisoning. 

· Soil compatibility: It is suitable for most soils, especially showing remarkable effects in soils lacking phosphorus or deficient in medium and trace elements. The availability of certain trace elements (such as iron and zinc) in alkaline soil will decrease. 

· Combined application: Although it is nutritionally comprehensive, it cannot completely replace organic fertilizer. When used in combination with organic fertilizers, it can improve soil structure and enhance fertilizer efficiency. 

· Avoid mixing: Do not mix with alkaline pesticides or fertilizers to prevent chemical reactions that reduce fertilizer efficiency or cause sedimentation.

• Summary

NPK 17-20-8 twelve-element compound fertilizer is a highly efficient fertilizer with strong functional targeting and comprehensive nutrition. Its "high phosphorus + full nutrition" design makes it an ideal choice for crops during the critical stages of root growth, flower promotion and fruit retention. It can effectively solve the growth problems caused by the imbalance of multiple nutrients in crops and help farmers achieve the goal of increasing production and improving quality.
