Application
Used as agricultural iron‑sulfur fertilizer to treat iron deficiency chlorosis. Suitable for acid-loving crops such as fruit trees, flowers, vegetables and seedlings. It can be applied by foliar spray, drip irrigation or soil base application to supplement iron and sulfur. It ameliorates saline‑alkali soil, activates soil nutrients, boosts chlorophyll synthesis, recovers green leaves and improves crop growth. Also used as raw material for water-soluble fertilizer and compound fertilizer.
