In agricultural production, crop growth requires not only macro‑elements such as nitrogen, phosphorus and potassium, but also amino acids, trace elements and functional nutrients. Amino‑acid‑based raw materials supply organic nitrogen sources for crops, boost nutrient uptake and improve physiological conditions; trace elements including iron, zinc, manganese and copper participate in plant photosynthesis, enzymatic activities and growth and development.

EDDHA‑Fe is a chelated iron source. Compared with ordinary iron salts, it features higher stability in soil. It is less prone to fixation by phosphate, hydroxide and other substances in soil, and remains effective across a wider pH range. Accordingly, EDDHA‑Fe is widely used for nutritional correction and foliar spray programs for fruit trees, vegetables, cash crops and iron‑deficiency‑sensitive crops.

Sichuan Tai‑Ao Technology Co., Ltd. provides raw‑material supply and application research for agricultural amino acids, EDDHA‑Fe and other products, delivering relevant product support for fertilizer enterprises, agricultural technical‑service companies and planting‑end clients.
