🌾1. Introduction: Why Calcium and Magnesium Fertilizers Matter
Calcium (Ca) and magnesium (Mg) are essential macronutrients for crop growth, playing critical roles in plant physiology, photosynthesis, and cellular structural stability. Calcium is a fundamental component of plant cell walls, directly influencing tissue strength, fruit firmness, and resistance to physiological disorders. Magnesium, as the central metal ion of chlorophyll, determines photosynthetic efficiency and overall plant energy metabolism.
Calcium deficiency often results in fruit cracking, blossom-end rot, weak cell structures, and reduced storage performance, while magnesium deficiency commonly causes interveinal chlorosis, reduced photosynthesis, and yield decline. These nutrient-related problems are widely observed in fruit trees, vegetables, and intensive cropping systems worldwide.
Although conventional calcium magnesium fertilizers are commonly applied, they often exhibit slow dissolution, uneven nutrient distribution, and limited root-zone availability, resulting in suboptimal fertilizer use efficiency. In response to these challenges, Risso has developed and patented a popcorn-structured calcium magnesium fertilizer, specifically designed to overcome the physical and chemical limitations of traditional formulations.
🔬 2. What Is a “Popcorn-Structured Calcium Magnesium Fertilizer”?
A popcorn-structured calcium magnesium fertilizer is a specially engineered Ca-Mg compound fertilizer characterized by a lightweight, expanded, and highly porous granular structure. The granules visually resemble popcorn, with a loose surface texture and a dense internal network of interconnected micro-pores.
This unique physical morphology dramatically increases the fertilizer’s effective contact area with water and soil solution, significantly accelerating nutrient dissolution and ion release. The structural concept is similar to that of high-performance adsorption and controlled-release materials used in advanced industrial applications.

Extremely High Specific Surface Area
The patented porous morphology provides a surface area multiple times greater than traditional calcium magnesium fertilizer granules, enhancing hydration and ion exchange efficiency. Rapid and Complete Dissolution
Water penetrates quickly through the micro-pore network, allowing calcium and magnesium to dissolve rapidly and uniformly without residual buildup.Enhanced Root Zone Distribution
The expanded, low-density granules disperse more evenly in soil, improving nutrient accessibility precisely within the active root absorption zone.
These advantages are direct outcomes of Risso’s patented popcorn-structured fertilizer technology, forming the basis for its high-efficiency nutrient absorption performance.
🧩 3. Core Design Principles of Popcorn-Structured Calcium Magnesium Fertilizer
1️⃣ Patented Porous Surface Technology
Unlike traditional homogeneous granules, popcorn-structured particles are produced using patented expansion and pore-forming technologies. This process creates abundant micro-channels on both the surface and interior of each granule.
These micro-channels significantly enhance water contact, promote capillary-driven nutrient migration, and shorten the diffusion path between nutrients and plant roots—resulting in faster and more efficient uptake.
2️⃣ High Water Solubility and Root Zone Nutrition
Popcorn-structured calcium magnesium fertilizers are typically formulated with 100% water-soluble nutrient sources, ensuring rapid ionization of Ca²⁺ and Mg²⁺ once applied.
After dissolution, nutrients distribute evenly within the soil solution or fertigation water, delivering immediate and uniform nutrition to the root zone. This feature makes the product particularly effective during peak demand stages such as flowering, fruit expansion, and stress recovery.
Typical Product Specifications (Reference Values):
- Calcium (Ca): 5-11%
- Magnesium (Mg): 4–13%
- Water Solubility: ≥ 99%
- pH (1% solution): 6.0 – 7.5
- Granule Size: 2–4 mm (expanded porous form)
- Appearance: Yellow or blue popcorn-like particles
(Exact formulations can be customized by Risso according to crop type and regional soil conditions.)
3️⃣ Designed for Precision Agriculture Systems
Thanks to its patented porous structure and high solubility, Risso popcorn-structured calcium magnesium fertilizer is fully compatible with fertigation, drip irrigation, sprinkler systems, and modern water-soluble fertilizer programs.
Its low residue and fast dissolution characteristics help minimize clogging risks while improving nutrient delivery accuracy—making it particularly suitable for precision agriculture and high-efficiency nutrient management systems.
🌱 4. How the Patented Porous Structure Enhances Nutrient Absorption Efficiency
✅ Accelerated Dissolution Kinetics
Traditional calcium magnesium fertilizers often require prolonged dissolution periods. In contrast, Risso’s patented popcorn-structured granules dissolve rapidly upon water contact, ensuring immediate nutrient availability for crops experiencing calcium or magnesium deficiency.
✅ Higher Root Nutrient Utilization Efficiency
The porous architecture allows dissolved nutrients to spread efficiently throughout moist soil zones, increasing contact with root surfaces and enhancing uptake efficiency—especially under fertigation and water-fertilizer integration practices.
✅ Balanced and Synchronized Calcium–Magnesium Supply
Simultaneous availability of calcium and magnesium prevents nutrient antagonism and secondary deficiencies. Magnesium supports chlorophyll synthesis and photosynthetic efficiency, while calcium strengthens cell walls and improves stress tolerance, promoting balanced crop development.
🍇 5. Application Advantages of Popcorn-Structured Calcium Magnesium Fertilizer
✔ Rapid Nutrient Correction
For fruit trees, vegetables, berries, and other high-value crops, rapid correction of Ca and Mg deficiencies is essential for yield stability and quality improvement. The fast-acting nature of Risso’s patented fertilizer ensures timely nutrient response.
✔ Improved Stress Resistance and Crop Quality
Balanced Ca-Mg nutrition enhances tolerance to drought, salinity, and temperature stress. Calcium improves fruit firmness and shelf life, while magnesium enhances photosynthetic efficiency and energy utilization.
✔ Wide Application Flexibility
Suitable for soil application, fertigation, foliar feeding (after proper dilution), and soilless cultivation systems, offering flexible nutrient management solutions for open-field and protected agriculture alike.
6. Comparison with Conventional Calcium Magnesium Fertilizers
| Key Indicator | Conventional Ca-Mg Fertilizer | Popcorn-Structured Ca-Mg Fertilizer |
|---|---|---|
| Dissolution Speed | Moderate | Fast |
| Nutrient Release Area | Low | High |
| Root Zone Availability | Average | High |
| Precision Agriculture Compatibility | Limited | Excellent |
| Nutrient Absorption Efficiency | Medium | High |
7. Conclusion: A Patented Innovation Shaping the Future of Crop Nutrition
As global agriculture continues to advance toward precision fertilization, high nutrient efficiency, and sustainable production, patented fertilizer technologies are becoming increasingly important.
With its proprietary popcorn-structured porous design, Risso’s patented calcium magnesium fertilizer delivers rapid, balanced nutrient supply while significantly improving fertilizer use efficiency. It offers growers a scientifically validated, future-oriented solution to enhance crop quality, stabilize yields, and reduce nutrient waste—setting a new benchmark for high-performance calcium magnesium fertilizers in modern agriculture.
