NPK 15-13-12 Potassium Sulfate Type For Medicinal Herbs And Potatoes Reliable Manufacturer Compound Fertilizer

• Product Overview of NPK 15-13-12 Special Fertilizer for Medicinal Potatoes

• NPK 15-13-12 Medicinal Potato Special Fertilizer is a highly efficient compound fertilizer scientifically formulated based on the specific growth patterns and nutritional requirements of Chinese medicinal materials (such as Astragalus membranaceus, Codonopsis pilosula, Salvia miltiorrhiza, licorice, etc.) and potatoes (potatoes). It precisely provides the three essential elements of nitrogen, phosphorus and potassium for crop growth, and specially adds a variety of trace elements. It aims to achieve the core goal of "promoting root growth and strengthening seedlings, expanding tubers, improving quality and increasing yield", and is the preferred fertilizer for ensuring high-quality and high-yield medicinal materials and potatoes.

• Core features and advantages

• The nutritional ratio is scientific and precise

· High nitrogen (N 15%) : Promotes lush stems and leaves in the early growth stage, establishes a powerful photosynthetic system, and accumulates sufficient nutrients for the expansion of tubers (rhizomes). 

· High phosphorus (P₂O₅ 13%) : Strongly promotes root development, making the root system well-developed and enhancing its absorption capacity. For tuber crops, phosphorus is crucial for energy transfer and tuber formation. 

· High potassium (K₂O 12%) : Specially designed for the tuber and rhizome expansion stage. Potassium can significantly enhance the transportation and accumulation of photosynthetic products to the tubers/roots, making the tubers larger and more uniform. At the same time, it increases the dry matter content and active ingredients of medicinal materials, as well as the starch content and storage and transportation resistance of potatoes.

· Promote root growth and strong seedlings, early emergence and rapid development: The abundant phosphorus content can stimulate root growth, enabling crops to form robust root systems during the seedling stage, absorb more water and nutrients, and lay a solid foundation for high yields. 

· Specifically designed for expanding tubers/roots: Balanced supply of nitrogen, phosphorus and potassium, preventing excessive growth, concentrating nutrients on underground economic products, effectively promoting the expansion and weight gain of underground tubers (potatoes) or roots (medicinal materials). 

· Enhance stress resistance and quality: Adequate potassium can strengthen crops' ability to resist drought, diseases and pests, and lodging. For medicinal materials, it can increase the content of their medicinal components. For potatoes, it can improve the taste, reduce hollow and black hearts, and increase the commercial rate. 

· Enhance fertilizer utilization rate: Advanced granulation technology is adopted, with uniform particles, good hardness, less prone to caking, moderate dissolution speed, and nutrient release that better conforms to the absorption laws of crops, reducing loss and fixation.

• Applicable crops and application period
  

Main applicable crops:

·All kinds of Chinese medicinal materials: especially suitable for varieties used as medicine with roots, rhizoids and tubers, such as Astragalus membranaceus, Codonopsis pilosula, Salvia miltiorrhiza, Glycyrrhiza uralensis, Rehmannia glutinosa, Pinellia ternata, Atractylodes macrocephala, Angelica dahurica, Achyranthes bidentata, etc. 

· Potato (potato) : Applicable to all varieties of potato cultivation.

Optimal application period:

· Base fertilizer (recommended) : Apply it all at once before sowing or transplanting, in combination with land preparation. As base fertilizer, it can comprehensively supply the basic nutrients of crops throughout their entire growth period. 

· Topdressing: It can be applied in furrows or holes during the critical growth period of crops, such as when the tubers or roots start to swell (potatoes at the bud stage and medicinal herbs at the middle growth stage), to meet the large nutrient requirements during the swelling period.

• Application method and recommended dosage

• Important Note: The following are general suggestions. The specific dosage should be adjusted according to local soil fertility, target yield and the guidance of agricultural technicians.

• Base fertilizer application (preferred method) :

· Spreading and deep ploughing: Evenly spread the fertilizer on the field surface and immediately carry out deep ploughing and ploughing. The depth is preferably 20-30 centimeters to ensure that the fertilizer is distributed in the root layer of the crops.

 · Row application/hole application: Apply fertilizer in the sowing furrows or holes, mix it slightly with the soil, and then sow or transplant. This can achieve centralized fertilization and improve the utilization rate of fertilizers.

 · Suggested dosage: Generally, it is recommended to apply 40 to 60 kilograms per mu (667 square meters). If the soil is poor or the target high yield is achieved, the weight can be appropriately increased to 70-80 kilograms.

• Top dressing application:

At the initial stage of the tuber expansion of the crop, dig a trench on one side of the plant (10-15 centimeters away from the root), apply the fertilizer, cover the soil and water. 

Suggested dosage: Apply 20 to 30 kilograms per mu.

• Precautions

· Soil testing and fertilization: It is recommended to conduct soil testing before application. If the potassium content in the soil is already high, the dosage can be appropriately reduced or other fertilizer ratios can be selected. 

· Deep application and soil covering: Whether it is base fertilizer or top dressing, it should be deeply applied and covered with soil to avoid surface broadcasting, so as to prevent nitrogen volatilization loss and the fixation of phosphorus and potassium. 

· Combined with organic fertilizer: When used in combination with fully decomposed farmyard manure or commercial organic fertilizer, it can improve soil quality, enhance fertilizer efficiency, and achieve a combination of land use and land conservation. 

· Avoid contact with seed fertilizer: When using seed fertilizer or applying it in holes, ensure that the fertilizer is kept at a distance of more than 5 to 10 centimeters from the seeds/seed potatoes to prevent seed and seedling burning. 

· Pay attention to trace elements: This fertilizer already contains some trace elements, but for certain medicinal materials with high requirements for specific elements (such as Astragalus membranaceus, which loves sulfur), additional supplementation may be necessary.

• Summary

• NPK 15-13-12 Medicinal Potato Special Fertilizer is a highly targeted functional fertilizer. It precisely meets the high requirements for the yield and quality of tubers and roots of crops through scientific nutrient ratios, and is an ideal assistant to help you realize your dream of a bountiful harvest in medicinal herb and potato cultivation.
