N (nitrogen) 15% : It provides the basic nutrients required for crop growth, promotes the growth of stems and leaves, and makes the plants lush and the leaves dark green. A nitrogen content of 15% is at a medium level, which can ensure the vegetative growth in the early stage and prevent excessive nitrogen from causing excessive growth or delaying the formation of tubers.
P₂O₅ (phosphorus) 13% : This is a prominent feature of this ratio. Phosphorus can effectively promote root development, enhance the stress resistance of crops, and play a key role in the formation, swelling and early maturation of tubers. For potatoes and medicinal materials whose roots and tubers are used for medicinal purposes, adequate phosphorus is the foundation for achieving high yields.
K₂O (potassium) 12% : Potassium can promote the transportation and accumulation of photosynthetic products, making tubers larger and plumper. At the same time, it can significantly improve the quality of crops, including increasing the starch content and storability of potatoes, as well as enhancing the accumulation of active ingredients in medicinal materials and their resistance to diseases, cold and drought.
Summary: The ratio of 15-13-12 precisely targets the goal of "promoting roots, strengthening stems, and expanding fruits", with particular emphasis on supporting the development of underground fruits (tubers and roots).
Main object: Potato (potato). This ratio is almost tailor-made for potatoes and can well meet their nutrient requirements from the seedling stage to the tuber expansion stage.
Main objects: Root and rhizome medicinal materials. For example:
Astragalus membranaceus, Codonopsis pilosula and licorice: They require well-developed root systems.
Rehmannia glutinosa, yam and Salvia miltiorrhiza: Their tubers or rhizomes are used as medicine and have a high demand for phosphorus and potassium.
Angelica dahurica and Isatis root: Other medicinal materials whose roots are harvested.
Other applicable crops: Sweet potatoes, taros, carrots, radishes, beets, and all other crops that are harvested from tubers and tubers.
Strong root system: High phosphorus content promotes the formation of well-developed and strong root systems in crops, enhancing their ability to absorb water and nutrients.
Promoting swelling: The synergistic effect of phosphorus and potassium significantly promotes the swelling and dry matter accumulation of underground tubers and roots, directly increasing the yield.
Improve quality: Increase the starch content of potatoes and the commercial potato rate; Enhance the appearance and content of active ingredients of medicinal materials.
Enhance resistance: Make the plant stems thick and strong, and increase their resistance to drought, low temperature, and pests and diseases.
Balanced growth: A balanced nitrogen content avoids the imbalance between vegetative growth (growing leaves) and reproductive growth (growing tubers), ensuring high and stable yields.
Soil testing and fertilization: The most scientific approach is to conduct soil testing first. If the soil itself has an extremely high phosphorus content, applying high-phosphorus fertilizers may lead to waste or even negative impacts.
Seed and fertilizer isolation: When used as base fertilizer, it is essential to ensure a safe distance of 5 to 10 centimeters from seeds or seed tubers to prevent seedling burning.
When used in combination with organic fertilizers: When used in conjunction with well-rotted farmyard manure or commercial organic fertilizers, it can improve soil structure, increase the utilization rate of chemical fertilizers, and provide comprehensive trace and medium elements.
Supplementing trace and medium elements: Although compound fertilizers provide macronutrients, potatoes and certain medicinal materials may have special requirements for trace and medium elements such as calcium, boron and zinc. For instance, potatoes lacking calcium are prone to end rot, and a deficiency of boron can affect the quality of the tubers. Foliar spraying or soil supplementation of corresponding micro-fertilizers can be carried out as needed.
