Dicalcium Phosphate DCP 16% Granular – Fertilizer Grade

Dicalcium Phosphate (DCP) 16% fertilizer is a phosphorus- and calcium-based nutrient product formulated to improve crop productivity and soil fertility in a sustainable manner. Phosphorus is one of the three primary macronutrients required for plant growth, playing a critical role in energy transfer, root formation, enzyme activation, and reproductive development. Calcium, as a secondary nutrient, contributes to cell wall strength, root tip growth, and improved resistance to physiological disorders in crops.

DCP 16% provides phosphorus in a combined form of water-soluble and citric acid–soluble phosphorus, which allows plants to absorb nutrients quickly after application while maintaining a stable nutrient supply over time. This dual-solubility characteristic reduces phosphorus fixation in the soil and improves overall fertilizer use efficiency, particularly in soils with high phosphorus-binding capacity.

Compared with highly acidic phosphate fertilizers, DCP 16% has a mildly acidic pH (≥5), which minimizes negative impacts on soil structure and microbial activity. It does not cause soil salinization and can be safely used over long-term cropping cycles. The absence of harmful ions such as chlorine and sodium further ensures crop safety, making it suitable for chloride-sensitive crops such as fruits, vegetables, tobacco, and certain horticultural plants.

DCP 16% is widely applied in fruit orchards, vegetable fields, greenhouse cultivation, and intensive farming systems where balanced phosphorus and calcium nutrition is required. It is also commonly used as a high-quality raw material in the production of compound fertilizers (NPK), water-soluble fertilizers, and specialty blended fertilizers.

Typical Specifications

Feeding / Application Instructions (Agricultural Use):

DCP 16% fertilizer can be applied through various fertilization methods depending on crop type, soil condition, and farming practices.

Base Fertilizer:

When applied as a basal fertilizer, DCP 16% helps establish a strong root system during early crop growth. Its sustained phosphorus release ensures continuous nutrient availability throughout critical growth stages.

Top Dressing:

DCP 16% can be used as a supplementary phosphorus source during flowering and fruit development stages to enhance yield, fruit set, and quality.

Compound Fertilizer Production:

Due to its stable chemical properties and granular form, DCP 16% is an excellent raw material for NPK compound fertilizers. It blends well with nitrogen and potassium fertilizers, ensuring uniform nutrient distribution in finished products.

Soil Improvement Programs:

In acidic or nutrient-imbalanced soils, DCP 16% contributes to improved calcium supply, helping stabilize soil structure and optimize nutrient uptake efficiency.
Application rates should be adjusted according to soil testing results, crop nutrient demand, and local agronomic recommendations.
