|---|---|
N (nitrogen) 20% : It provides a large amount of nitrogen required for crop growth, mainly promoting the growth of stems and leaves, increasing chlorophyll content, making the plants lush and the leaves dark green. A content of 20% belongs to a medium to high nitrogen level.
P₂O₅ (phosphorus) 15% : It provides a large amount of phosphorus, mainly promoting root development, flower bud differentiation, pollination and fertilization, and early fruit ripening. A 15% content can effectively meet the phosphorus requirements of crops in the early stage and during the flowering and fruiting period.
K₂O (potassium) 10% : It provides a large amount of potassium, mainly enhancing the crop's stress resistance (cold resistance, drought resistance, disease and pest resistance), promoting the transportation of photosynthetic products, plump grains, fruit enlargement and coloring, and improving quality. A potassium content of 10% is suitable for crops with moderate potassium requirements or as base fertilizer.
Advantages: The formula is flexible and can be "tailored" according to the soil nutrient status and crop requirements, with relatively low costs.
Note: The particle size and specific gravity of each raw material should be similar; otherwise, separation is likely to occur during transportation and use, resulting in uneven nutrient distribution.
Core features: Free of chloride ions (Cl⁻) or with extremely low content.
Wide range of applicable crops: Particularly suitable for "chlorine-sensitive crops" that are sensitive to chloride ions.
Enhancing quality: It can provide sulfur for crops. Sulfur is essential for the synthesis of proteins and vitamins, which helps increase the sugar content, color and aroma of fruits.
Soil improvement: Long-term use will not cause soil salinization and is suitable for saline-alkali land.
| Major component | N + P2O5 + K2O |
| Inorganic substance content | N + P2O5 + K2O ≥ 45.0% (20-15-10) |

| Category | Potassium sulfate type |
| Aim | Field crops and various cash crops |
Balanced nutrition and reasonable ratio: A nitrogen, phosphorus and potassium ratio of 20-15-10 (approximately 4:3:2) belongs to a high-nitrogen, medium-phosphorus and medium-potassium formula, which is very suitable for the nutritional needs of crops from the early to the middle growth stage.
Potassium sulfate source, quality choice: It ensures the safety of chlorine-sensitive crops while supplementing sulfur elements, enhancing the appearance and internal quality of agricultural products.
Promote growth and strengthen plants, strengthen roots and protect fruits: High nitrogen promotes vegetative growth, medium phosphorus ensures well-developed root systems and vigorous flower buds, and medium potassium enhances plant resistance and lays a foundation for later yields.
Good physical properties: Made from high-quality raw materials, the particles are uniform, not prone to caking, and convenient for mechanical and manual application.

Vegetables: tomatoes, cucumbers, peppers, potatoes, Onions, garlic, lettuce, cabbages, cauliflower, etc.
Cash crops: tobacco, tea, sugarcane, sugar beets, etc.
Medicinal materials: ginseng, Notoginseng, etc.
It is mainly used as base fertilizer: applied during land preparation before sowing or transplanting, providing comprehensive and balanced basic nutrients for the entire growth period of crops.
It can also be used as an early topdressing: applied during the early growth stage of crops (such as the green-up stage and the tillering stage) to promote rapid plant growth.
Q:How often should fertilizer be applied? | |
A:It is usually applied during the main growing seasons of plants (spring and summer), once a month or as per the product instructions. When plants grow slowly or go dormant in autumn and winter, fertilization should be reduced or stopped. | |
Q:Can it be used together with organic fertilizer? | |
| A:Sure, but the total amount needs to be noted. Compound fertilizers take effect quickly, while organic fertilizers have a long-lasting effect and can improve soil quality. The combination of the two yields even better results. It is recommended to appropriately reduce the dosage of compound fertilizer. | |
Q:How to store unused fertilizer? | |
| A:Please store the fertilizer in a cool, dry and dark place and seal the packaging bag well. Dampness can cause fertilizers to clump and become ineffective. |
