Tianjin Rongda Fertilizer recently launched a N28-P2O510-K2O10Biological amino acids. This product combines the company's research and development achievements in the field of environmentally friendly fertilizers, and is closely related to its experience in collaborative development with Shandong Agricultural University and provincial fertilizer research institutes. It is a new product in the series of bio-chelated fertilizers and amino acid slow-release fertilizers, and is now officially on the market. The main purpose of this fertilizer is to provide long-term nutrition to crops. Unlike traditional fertilizers that dissolve and dissipate rapidly, it controls the release of nutrients, releasing them slowly according to the crop's growth needs. This extends the fertilizer's effective period, allowing the crop's roots to continuously absorb amino acids and various nutrients, preventing excessive vegetative growth in the early stages and nutrient deficiency in the later stages. Many growers have reported that after using it, the leaves of wheat and corn in the field are darker in color, and the stems are stronger.
