Agricultural Water Soluble Fertilizer
Agricultural field (main application) (1) High-efficiency Potassium Fertilizer & Nitrogen Fertilizer – Provide essential potassium (K) and nitrogen (N) for plants, promoting plant growth and enhancing stress resistance (drought resistance, cold resistance, disease and pest resistance). – Advantages: – Does not contain chlorine , suitable for crops that are sensitive to chlorine (such as tobacco, citrus, potatoes, grapes, etc.). – Good water solubility, suitable for precise fertilization methods such as drip irrigation and foliar spraying. – Applicable crops: – Cash crops: tobacco, tea, fruits (citrus, grapes, strawberries, etc.), vegetables (tomato, cucumber, etc.). – Field crops: wheat, corn, rice (needs to be combined with other fertilizers).
(2) Water-soluble Fertilizer & Foliar Fertilizer – Used for high-end water-soluble fertilizer formulations (such as those based on Israeli and Dutch integrated water and fertilizer technology). – Foliar spraying can quickly replenish potassium and nitrate nitrogen, improving fruit quality (such as enhancing sweetness and coloration).
(3) Soilless Cultivation & Grouped Seedling Production – As the core component of the nutrient solution (such as the Hoggland nutrient solution formula).
