CALCIUM POWER (CALCIUM POWER)

Phosphorus & Sulfur Compatible + Stable Calcium Supply + Transparent & High-Efficiency: All-Purpose CALCIUM POWER Liquid Fertilizer

This product is a highly efficient transparent liquid calcium fertilizer with a density of 1:1.42 and a core formula containing calcium >150g/L. Using an advanced formulation, it does not react with phosphorus (P) or sulfur (S), breaking through the industry pain point of antagonism between ordinary calcium fertilizers and phosphorus/sulfur. It achieves deep synergy of “phosphorus-sulfur compatibility + stable calcium supply + transparent high efficiency”. Relying on the excellent stability of the transparent liquid, it integrates multiple functions: rapid nutrient supplementation, deficiency correction, quality improvement, and convenient compounding. Suitable for all crops throughout the growth period, especially for high-calcium-demanding crops, it is an excellent liquid fertilizer for efficient calcium supplementation and avoiding nutrient waste.

1. Mutual Enhancement: Formulation Synergy and Density Adaptation The transparent liquid form with a density of 1:1.42 features good fluidity and uniform nutrient distribution, allowing calcium and formula components to fully integrate and work synergistically. The core advantage is its exclusive formulation that does not react with phosphorus or sulfur, avoiding precipitation and nutrient loss caused by the combination of ordinary calcium fertilizers with P and S. It also enhances calcium activity through ion synergistic technology, while the transparent liquid structure ensures stable nutrient release, achieving triple benefits of “stable calcium supply + efficient absorption + flexible compounding” for diverse fertilization scenarios.

2. Stable Calcium Supply: Precise Correction of Deficiency Symptoms With calcium content >150g/L, it provides sufficient absorbable calcium for crops, quickly absorbed through roots and leaves to accurately correct calcium deficiency symptoms such as blossom-end rot, fruit cracking, and weak stems. As a core component of cell walls, calcium promotes the synthesis of calcium pectate, strengthens cell wall strength and stability, improves plant toughness, and facilitates calcium transport to fruits and new tissues, laying a solid foundation for robust growth, high yield and quality.

3. Phosphorus & Sulfur Compatibility: Breaking Antagonism for Easy Compounding Using a unique advanced formula, it fundamentally avoids reactions with phosphorus and sulfur, completely solving the problem of easy precipitation and nutrient loss when ordinary calcium fertilizers are mixed with P- and S-containing fertilizers. It can be flexibly mixed with phosphorus-containing, sulfur-containing and other water-soluble fertilizers without separate preparation, improving fertilization convenience, avoiding waste from nutrient antagonism, greatly enhancing overall fertilization efficiency, and meeting compounding needs of large-scale planting.

4. Transparent & Stable: Adaptable to Diverse Application Scenarios The transparent homogeneous liquid form is free of precipitation and caking, with excellent stability. It disperses quickly when mixed and does not clog irrigation or spraying equipment. The density of 1:1.42 balances nutrient concentration and fluidity, suitable for foliar spray, drip irrigation, and fertigation. It meets precise fertilization for intensive fruit and vegetable cultivation as well as bulk application for large-scale fields, combining efficiency and practicality.

5. Quality Improvement & Efficiency Enhancement: Broad Adaptability & Value Added Suitable for fruits, vegetables, grains, oils and cash crops, especially high-calcium-demanding crops such as tomatoes, apples and citrus. Calcium synergizes with formula components to not only prevent physiological diseases caused by calcium deficiency but also increase fruit firmness, reduce cracking and drop, improve soluble solids content, enhance storage and transport tolerance, and boost market competitiveness. High stability and compatibility achieve “low waste, high effect”, significantly improving fertilizer utilization rate, balancing calcium supply effect and planting cost control.

Expert Recommendations: Suitable for calcium supplementation in all crops throughout the growth period, especially for high-calcium-demanding fruits and vegetables and calcium-deficient fields. For foliar spray, dilute 800–1500 times and spray evenly on both sides of leaves, avoiding high temperatures. For drip irrigation and fertigation, it can be directly mixed with phosphorus-containing, sulfur-containing and other conventional fertilizers, adjust dosage as needed, apply once every 7–10 days, with better results for 2–3 consecutive applications. The transparent liquid dissolves easily without pre-soaking, compatible with conventional irrigation and spraying systems; avoid mixing with strongly alkaline products.

Application & Dosage: CALCIUM POWER

Application Advice: This product is suitable for foliar spray and drip irrigation; foliar spray is recommended for faster nutrient absorption. Foliar spray: dilute 800–1500 times, 1200–1500 times for seedling and tender tissues, spray evenly on both sides of leaves and fruit surfaces, once every 7–10 days for 2–3 consecutive times. Drip irrigation: dilute 500–800 times, apply evenly with irrigation water at 2–3L per mu. Shake well before use to ensure uniform distribution of high-concentration nutrients and avoid excessive local concentration.

Fertilizer Manufacturing and Blending

  • Liquid Fertilizer Compounding:
    With 150g/L high-concentration calcium, it can be used as core raw material to formulate high-end fruit swelling fertilizers and secondary element liquid fertilizers, improving calcium supplementation effect and commercial value of finished products, suitable for large-scale fertilizer production.
  • Custom Foliar Fertilizer:
    Excellent compatibility of sugar alcohol chelation system, can be compounded with trace elements such as boron and zinc to create special foliar fertilizer for flower and fruit retention, no antagonistic reaction, strengthening synergistic quality improvement effect.
