In fertilizer management and blending operations, confusion among fertilizers with similar appearances (such as common white urea and diammonium phosphate) often occurs during storage, transportation, and on-site BB fertilizer blending, bringing unnecessary risks to agricultural production. RONGDA Gray Granular Fertilizer is a practical solution developed for this pain point. Its unique gray appearance, derived from natural calcium sources rather than artificial pigments, serves as a visual identification mark, enabling quick distinction from other fertilizers.

RONGDA Imported Calcium Ammonium Nitrate originates from Europe, adopting top local production technology and inheriting a century of European agricultural production experience. As a high-quality fertilizer recognized by global growers, it features strict production control, stable performance, wide application in high-end agricultural fields, and complete traceability. The product can provide continuous and balanced nutrient supply for crops, meet the needs of green and high-end agricultural production, and is easy to store and use.

In agricultural planting, rational fertilization is key to improving crop yield and quality. Tianjin Rongda Fertilizer Co., Ltd.'s 19-31-4 Blended fertilizer（Potassium-containing diammonium type） offers farmers a new high-quality option. This pure potassium sulfate-type diammonium-containing blended fertilizer has a wide range of applications. It provides comprehensive and balanced nutrition to various crops, benefiting both grain crops like wheat and corn, and cash crops like vegetables and fruits. At different stages of crop growth, this fertilizer precisely targets their nutrient needs, helping crops thrive.

In the current context of the continuous development of ecological agriculture, 19-19-19 Blended Fertilizer has become the preferred choice for growers due to its innovative technology. Tianjin Rongda Fertilizer Co., Ltd., drawing on over ten years of experience in environmentally friendly fertilizer research and development, has combined biotechnology with traditional processes to launch this new type of fertilizer that enhances soil vitality and reduces reliance on chemical fertilizers. This fertilizer uses ammonium sulfate, ammonium chloride, and other basic nutrients as its core, employing bio-coating technology to evenly coat nitrogen-fixing bacteria on the surface of the granules. This design allows beneficial bacteria to continuously function in the soil, converting atmospheric nitrogen into nutrients that plants can absorb, effectively reducing nitrogen fertilizer loss. For field crops such as corn and wheat, it results in more developed root systems and significantly enhanced lodging resistance; in fruit-growing areas, it improves leaf thickness and increases fruit set by approximately 15% compared to traditional fertilization.

18-25-5 Blended fertilizer（Potassium-containing diammonium type）, developed by Tianjin Rongda Fertilizer Co., Ltd. to meet the needs of modern agriculture, uses ammonium sulfate and diammonium phosphate as base materials, scientifically formulated with potassium sulfate and other nutrients to form a formula system that synergistically supplies nitrogen, phosphorus, and potassium. Its core advantage lies in the precise matching of nutrient release rhythm with crop absorption patterns, making it particularly suitable for the critical growth stages of cash crops and field crops. It can effectively improve fertilizer utilization and reduce nutrient loss.

In the vast realm of agricultural production, fertilizer, as the "nutritional meal" for crops, is undeniably crucial. Tianjin Rongda Fertilizer Co., Ltd., a modern enterprise rooted in Jinghai District, Tianjin since 2011, is injecting new vitality into ecological agriculture with innovation and green development as its two wings. 18-18-18 Blended fertilizer, one of Rongda Fertilizer's flagship products, has become the first choice for many farmers due to its scientific formulation and efficient utilization.
