Granustar®

For Field-Grown Crops

Granustar® CRF is a professional controlled-release fertilizer tailored specifically for open-field crops. As a cost-effective alternative to Field-Cote®, it offers reliable performance thanks to Mivena’s patented Durable® CRF coating technology, which ensures nutrients are released gradually and predictably over a defined three-month period.

• Based on Mivena’s Durable® CRF coating, designed for a consistent and efficient nutrient release without spikes—even under warmer conditions.

• Supports soil health: no sudden nutrient surges, making it gentle on soil microbiology.

• Delivers a complete nutritional profile with Nitrogen (N), Potassium (K), Magnesium (MgO), Calcium (CaO), and key trace elements (Fe, Mn, Zn, B, Cu, Mo).

• Low in chloride and nitrate, with reduced risk of volatilization or leaching.

• Uniform granule size (1–4 mm) ensures even spreading and precise application.

• Effective over a 3-month longevity, minimizing the need for repeat applications and reducing labor input.

Granustar® CRF is ideal for growers looking to streamline fertilization in vegetable production, fruit cultivation, or other open-field systems, without compromising on performance or crop quality. Its balanced formulation and reliable release curve make it a trusted tool for season-long nutrition in diverse field conditions.
