Description
Cassava & Sweet Potato Fertilizer Detailed Specifications
DONGKWANG Cassava & Sweet Potato Fertilizer is specifically formulated for tuber crops, providing the precise nutrient balance to optimize root/tuber yield, carbohydrate accumulation, and overall crop health.
Technical Specifications
| Nutrient | Typical Content / Feature |
|---|---|
| Nitrogen (N) | Supports early vine and foliage growth, establishing strong vegetative foundation before tuber bulking. |
| Phosphorus (P₂O₅) | Enhances early root development and tuber initiation for optimal establishment. |
| Potassium (K₂O) | Critical for tuber bulking, starch accumulation, water regulation, and improved tuber size and quality. |
| Secondary & Micronutrients (S, Mg, B, Zn) | Ensures metabolic efficiency, prevents nutrient deficiencies, and promotes healthy tuber and vine growth. |
| Physical Form | Free-flowing granules for uniform soil application — suitable for manual or mechanical use. |
| Application Methods | Basal application at planting; top-dress or side-dress during tuber growth as needed. |
Key Features & Agronomic Advantages
-
Optimized Nutrition for Tuber Crops: Specifically designed for cassava and sweet potato to meet their high potassium demand and balanced nutrient needs.
-
Supports Root and Vine Growth: Promotes vigorous foliage development early, then enhances tuber bulking and carbohydrate accumulation.
-
Improves Tuber Yield & Quality: Adequate nutrition increases tuber size, starch content, and overall yield per hectare.
-
Versatile & Easy to Apply: Granular form allows soil incorporation at planting or flexible top-dressing during crop growth.
- Efficient Nutrient Release: Gradual release matches crop uptake, reducing nutrient losses and improving fertilizer use efficiency.
Recommended Application Strategy
-
Planting / Basal Application: Apply at planting to ensure essential nutrients for early root and tuber development.
-
Top-dress / Side-dress During Growth: Apply additional fertilizer during vine growth or before tuber bulking to maximize tuber size and starch content.
-
Cassava Cultivation: Supports root yield, starch accumulation, and consistent high-quality harvest.
-
Sweet Potato Cultivation: Enhances tuber formation, size, and quality for table, processing, or storage.
- Variable Soil & Climate Conditions: Suitable for irrigated or rainfed systems, improving resilience and nutrient use efficiency.
Usage Guidelines
-
Conduct soil tests to determine baseline nutrient levels and tailor fertilizer rates.
-
Apply split nitrogen and potassium doses to support early growth and tuber bulking while preventing excessive foliage.
-
Ensure adequate soil moisture for optimal nutrient dissolution and uptake.
-
Include secondary and micronutrients as required to prevent deficiencies and maintain crop health.
- Adjust fertilizer rate to crop variety, growth stage, and yield goals for best results.
Agronomic & Market Context
-
Cassava and sweet potato are high-value tuber crops with strong nutrient demands, particularly potassium and phosphorus, for optimal tuber bulking and starch accumulation.
-
Poor nutrient management can reduce tuber size, yield, and quality, undermining economic returns.
- DONGKWANG Cassava & Sweet Potato Fertilizer ensures balanced nutrient supply, promotes uniform growth, improves tuber quality, and enhances yield stability — supporting sustainable and profitable tuber crop production.
Packaging & Storage
-
Packaging: 10 kg, 25 kg bags; bulk bags available for large-scale applications.
-
Storage: Keep in a cool, dry, ventilated area; protect from moisture, direct sunlight, and high temperatures.
-
Handling: Easy to spread manually or mechanically; compatible with standard farm fertilizer application equipment.
