Bulk Blending Fertilizer 15-13-12 (Sulfur Based)

Product Overview

• Product Name: Special Fertilizer for Medicinal Materials/Special Compound Fertilizer for Chinese Medicinal Materials

• General model: NPK 15-13-12 (Total nutrients ≥40%)

• Positioning: A high-concentration, nutritionally balanced compound fertilizer specifically designed to meet the growth and active ingredient accumulation needs of medicinal plants.

Interpretation of the formula meaning: NPK 15-13-12

• N (nitrogen) 15% :Promotes the growth of stems and leaves, making the plant lush and the leaves dark green. It is particularly important for medicinal materials that are used in the form of leaves or the whole plant, such as mint, agastache, and andrographis paniculata.

• P (phosphorus) 13% : Promotes root development, enhances tillering, accelerates flower bud differentiation, and improves the crop's stress resistance (cold and drought resistance). It is a key element for root and rhizome medicinal materials (such as ginseng, codonopsis pilosula, Astragalus membranaceus, and Salvia miltiorrhiza) and medicinal materials used in the form of fruits and seeds.

• 12% K (potassium) : Enhances photosynthesis, promotes the synthesis and transportation of carbohydrates and sugars, and causes the roots and stems to swell and the fruits to be plump. It can significantly increase the yield and quality of medicinal materials, while enhancing their disease resistance and lodging resistance. It is crucial for the quality formation of almost all medicinal materials, especially root and stem medicinal materials and fruit medicinal materials.

Product advantages

• Highly targeted: Scientifically formulated based on the physiological characteristics and nutrient absorption patterns of medicinal plants, it is different from the fertilizers used for ordinary field crops.

• Balanced nutrition: The harmonious proportion of the three major elements not only ensures the vigorous growth of plants but also prioritizes the expansion and nutrient accumulation of underground roots, stems, fruits and grains. It directly affects the final yield and the content of medicinal components (such as saponins, polysaccharides, and alkaloids).

• Promoting root growth and strengthening seedlings: A higher phosphorus content can effectively stimulate root development and form a strong root community, which is crucial for medicinal materials that require "digging up the roots immediately after harvest".

• Enhancing resistance: Adequate potassium can strengthen the drought resistance, cold resistance, and disease and pest resistance of medicinal materials, reduce the use of pesticides, and better meet the cultivation requirements of green Chinese medicinal materials.

• Improving quality: By providing balanced nutrients, problems such as excessive growth, poor green color, and lodging caused by excessive nitrogen fertilizer application can be avoided, ensuring that the medicinal materials have a good form, accumulate more dry matter, and have a high content of effective components.

• Usually, trace elements and medium elements are added: Many high-quality fertilizers specifically designed for medicinal materials also add trace elements and medium elements such as calcium, magnesium, sulfur, zinc, boron and iron to prevent nutrient deficiency and ensure the healthy growth and quality integrity of medicinal materials.

  

  
  

  

  
  

Product application

This fertilizer has a very wide range of applications, especially suitable for the following types of medicinal materials:

• Root and rhizome medicinal materials: ginseng, American ginseng, Notoginseng, Astragalus membranaceus, Codonopsis pilosula, licorice, Salvia miltiorrhiza, Scutellaria baicalensis, Rehmannia glutinosa, Atractylodes macrocephala, Paeonia lactiflora, Angelica dahurica, Ophiopogon japonicus, Fritillaria, etc. These medicinal materials have a particularly high demand for phosphorus and potassium.

• Whole herbs and leafy medicinal materials: mint, agastache, Perilla, andrographis paniculata, dandelion, etc. They need sufficient nitrogen to support the growth of stems and leaves, and also require phosphorus and potassium to enhance their physical strength and increase the effective components.

• Fruit and seed medicinal materials: wolfberry, cornus officinalis, Schisandra chinensis, Forsythia suspensa, gardenia jasminoides, sea buckthorn, etc. The demand for phosphorus and potassium increases during the flowering and fruiting period. This formula can well support fruit setting and fruit development.

• Floral medicinal materials: such as honeysuckle, chrysanthemum, etc.

NPK 15-13-12 Medicinal Herb Special Fertilizer is a scientific and highly efficient professional fertilizer. It can fully meet the nutrient requirements of most medicinal plants throughout their growth cycle. By promoting root development, balancing plant growth, and enhancing stress resistance, it ultimately achieves the core goals of increasing production, improving quality (increasing the content of active ingredients), and raising income. It is an ideal fertilizer choice for modern standardized (GAP) cultivation of Chinese medicinal materials.
