Comprehensive NPK fertilizer DripFert™ 5-15-40+micronutrients (B, Cu, Fe, Mn, Zn) with increased phosphorus and potassium content is used for all types of crops — strawberries, vegetables (tomatoes, cucumbers, peppers), grapes, field crops (wheat, corn, rapeseed, sunflower). Fertilizers with increased phosphorus content are necessary for plants that are beginning to form flower buds. Phosphorus fertilizers are used to stimulate flowering of mature rosettes and also significantly affect the abundance of flowering. Plus, increased potassium is required by plants to achieve good yields.
