Magnesium Calcium Silicate Black Granular Fertilizer
Product Features
I. Core Product Characteristics:
1. Slow-release and long-lasting: The black granules form a natural protective film, allowing nutrients to be released slowly with soil moisture, preventing loss and meeting the nutrient needs of crops throughout their entire growth cycle.
2. Strong adaptability: Resistant to acids and alkalis, and high temperatures; it does not antagonize organic fertilizers or NPK compound fertilizers, and does not damage the original nutrient structure of the soil.
3. Safe and environmentally friendly: Non-toxic and non-corrosive; it does not pollute soil or water sources after application, does not affect soil microbial activity, and conforms to green agricultural practices.
4. Soil Improvement: Black granules contain active mineral components, which can activate and fix nutrients in the soil, preventing soil compaction, and are especially suitable for improving acidic soils.
II. Core Functions and Effects (Individual Element + Comprehensive Effects)
(I) Core Functions of Single Elements
1. Silicon: Strengthens crop cell walls, thickens the stem cuticle, and enhances resistance to lodging and pests (reducing diseases such as sheath blight and rice blast); promotes root development and enhances drought and cold resistance; improves the quality of agricultural products and increases the sugar content of fruits.
2. Calcium: Supplements crop Essential calcium, prevents physiological disorders such as fruit cracking, blossom-end rot, and bitter pit; enhances fruit firmness, extends shelf life and storage/transport capacity; promotes root growth, and improves nutrient absorption efficiency.
3. Magnesium: A core component of chlorophyll, quickly alleviates magnesium deficiency chlorosis in crops, promotes thick, dark green leaves, and improves photosynthetic efficiency; aids in carbohydrate synthesis and transport, increasing crop yield; improves the taste and quality of agricultural products.
4.Chelated micronutrients: Supplements deficient nutrients such as zinc and boron, prevents problems like little leaf disease and fruitless flowering, achieving a balanced nutrient supply.
(II) Comprehensive Effects
1. Soil Improvement: Neutralizes soil acidity, regulates soil pH, loosens compacted soil, increases soil aeration, and activates fixed nutrients such as phosphorus and potassium in the soil.
2. Quality and Yield Enhancement: Synergistically promotes crop growth, reduces flower and fruit drop, increases fruit set rate, and achieves a 10%-30% increase in yield; improves the appearance and internal quality of agricultural products, and enhances their commercial value.
3. Soil Fertility Improvement: Long-term application can increase soil organic matter and micronutrient reserves, improve soil fertility, and achieve a combination of land use and soil maintenance.
III.Scope of Application and Application Method
(I) Scope of Application
1. Applicable Soil: Acidic soils, compacted soils, and soils with continuous cropping obstacles are preferred; neutral and slightly alkaline soils are also suitable.
2.Applicable Crops: Field crops (rice, wheat, corn, cotton, peanuts, etc.); cash crops (vegetables, fruit trees, tea, tobacco, medicinal herbs, etc.); especially suitable for crops with high silicon, calcium, and magnesium requirements (rice, tomato, citrus, grapes, watermelon, etc.)
(II) Application Method
1. Base Fertilizer Application (Recommended): Before sowing/transplanting, evenly spread granular fertilizer on the soil surface and then till it into the deeper soil layers (15-20cm depth) during tillage. Fertilizer Application:20-40 kg per mu (approximately 0.067 hectares); mix with well-rotted organic fertilizer and compost for 3-5 days before application to increase fertilizer efficiency by 30%.
2. Topdressing Application: During the crop growth period (fruit expansion stage of fruit trees, fruiting stage of vegetables), apply in trenches/holes around the crop roots, cover with soil and water after application. 10-20 kg per mu.
3. Root Dipping: For transplanted crops such as rice and vegetables, crush granular fertilizer (small amount) and mix with fine soil, add water to form a paste, and dip the seedling roots during transplanting to promote seedling establishment. 5-10 kg per mu.
4. Combination Suggestion: Use in combination with NPK compound fertilizer for nutrient complementarity. Avoid applying directly to the same planting hole as strong acid fertilizers to prevent neutralization and ineffectiveness.
Ⅳ.Precautions
1. Maintain a 5-10cm distance from crop roots during application to avoid root burn.
2. Store in a dry, well-ventilated place, avoiding rain and moisture.
3. Adjust the dosage according to soil fertility and crop variety; increase the dosage appropriately for acidic soils.
4. This product is a slow-release fertilizer, and its effects are slightly slower than fast-acting fertilizers. It is recommended to apply it 7-10 days in advance.
