Rongda Calcium Magnesium Granules is a premium secondary nutrient fertilizer from Rongda, a specialized Chinese manufacturer. Calcium strengthens plant cell walls and reduces fruit cracking, while magnesium boosts chlorophyll synthesis and photosynthetic efficiency. Ideal for acidic soils and high-value fruit and vegetable crops, it precisely fills nutrient gaps, enhances crop stress resistance, and lays a solid foundation for quality yields.

Core Product Advantages

1. Sustained-Release, Long-Lasting Nutrition

Manufactured with advanced granulation technology, Rongda Calcium Magnesium Granules dissolve gradually, delivering nutrients steadily over an extended period. Unlike quick-release fertilizers, one basal application covers most of the growing season, reducing topdressing frequency and labor costs. Slow nutrient dissolution minimizes leaching waste and improves overall fertilization efficiency.

2. Acidic Soil Amendment

As an alkaline fertilizer, these granules are perfectly suited for acidic red soils and acidified fields from overuse of chemical fertilizers. They neutralize soil acidity and alleviate aluminum and manganese toxicity. By promoting soil aggregate structure, they reduce compaction, improve aeration and water retention, and boost uptake efficiency of NPK nutrients.

Storage and Application Features

Rongda Calcium Magnesium Granules offer stable physical properties with high hardness, excellent crush resistance and anti-caking performance. No special moisture-proof storage is required. Uniform particle size and good flowability ensure smooth mechanical broadcasting without clogging. Sourced from quality raw materials with stable supply, the product delivers outstanding cost-effectiveness.

Application Scenarios

Suitable for field crops like rice, corn and wheat as base fertilizer to prevent premature senescence and leaf yellowing. For fruits and vegetables — apples, citrus, grapes, tomatoes and peppers — it reduces cracking and physiological disorders, improving firmness and shelf life. Especially effective in acidic soil regions. Also an excellent ingredient for compound and bulk blended fertilizers.
