GROWMAX-Ca is a high-efficiency chelated calcium fertilizer formulated with advanced EDTA chelation technology, which protects calcium from soil fixation and reduces antagonistic interactions with other nutrients, ensuring stable availability and efficient uptake by crops. It can be rapidly absorbed by both leaves and roots without relying solely on transpiration flow, improving calcium mobility and transport within plants. GROWMAX-Ca provides a continuous calcium supply throughout crop growth, effectively preventing and correcting calcium deficiency disorders such as fruit cracking, tip burn, blossom end rot, and soft fruit. Meanwhile, it promotes root development, enhances nutrient absorption capacity, improves fruit firmness and quality, and extends post-harvest storage life.
