Calcium Ammonium Nitrate Yellow Granular Fertilizer

1. Dual-Nitrogen Synergy: Combining Rapid Action with Long-Lasting Effects

Calcium Ammonium Nitrate Yellow Granular utilizes a scientifically formulated dual-nitrogen ratio technology, containing both nitrate nitrogen and ammonium nitrogen—two distinct forms of nitrogen that complement each other and work synergistically. Nitrate nitrogen requires no decomposition by soil microorganisms and can be directly absorbed by crop root systems; thus, it acts rapidly upon application, quickly alleviating symptoms of nitrogen deficiency in crops. It promotes seedling establishment and foliage growth, effectively meeting the high nitrogen demand during the early and vigorous growth stages of crops. Conversely, ammonium nitrogen is released slowly within the soil, providing a durable and stable fertilizer effect. This slow-release mechanism prevents nutrient loss, root burn, and seedling damage—risks often associated with the rapid, one-time release of nitrogen—while ensuring a continuous supply of nitrogen throughout the mid-to-late growth stages. By maintaining steady crop growth and preventing premature senescence caused by late-stage nutrient depletion, this product achieves a perfect balance between "rapid action" and "long-lasting effects." It significantly boosts nitrogen utilization efficiency—improving it by over 20% compared to traditional single-nitrogen fertilizers—thereby minimizing fertilizer waste.

2. Highly Active Water-Soluble Calcium: Significant Efficacy in Calcium Supplementation and Disease Prevention

This product is rich in highly active, water-soluble calcium. Calcium is a core nutrient component of crop cell walls and plays a direct role in cell division, cell elongation, and nutrient transport; it is an indispensable secondary nutrient for crop growth. The calcium in Yellow Calcium Ammonium Nitrate exists in a water-soluble form, offering a much higher absorption and utilization rate than traditional calcium fertilizers. It can be rapidly absorbed through the roots and leaves, then translocated to all active growth points within the plant. This effectively prevents various physiological calcium deficiency disorders, such as blossom-end rot in tomatoes and peppers; bitter pit in apples and pears; tip burn in Chinese cabbage and head cabbage; and fruit cracking, malformation, and hollowness in various melons and fruits. Furthermore, this active calcium enhances the thickness and resilience of crop cell walls, thereby boosting the plant's resistance to lodging, pests, diseases, cold, drought, and soil salinity/alkalinity. By mitigating the adverse effects of environmental stressors on crop development, it strengthens the plant's overall stress tolerance and fosters robust, healthy growth. 

3. Physiologically Neutral: Improving the Soil Environment

Unlike traditional acidic or alkaline nitrogen fertilizers, Yellow Calcium Ammonium Nitrate is a physiologically neutral fertilizer. Long-term application does not lead to soil acidification or salinization issues; instead, it effectively regulates soil pH, neutralizes acidic substances in the soil, and improves the physicochemical properties of acidic or compacted soils. Once applied, the product promotes the formation of soil aggregate structures, loosening the soil and breaking up compaction. This enhances soil aeration and water permeability, optimizes the living environment for soil microorganisms, increases the population of beneficial microbes, and accelerates the decomposition of soil organic matter. Consequently, the soil becomes looser and more fertile, with improved water and nutrient retention capabilities. This fundamentally improves the root growth environment, preventing issues such as weak roots, root rot, and poor nutrient uptake caused by soil-related problems, thereby integrating the utilization of land with its conservation to ensure sustainable agricultural cultivation.

4. Excellent Physical Properties: Convenient and Safe Application

The product consists of uniform yellow granules characterized by consistent particle size and high hardness. Processed using a specialized technique, it exhibits extremely low hygroscopicity; it does not cake or turn to powder during long-term storage or transport, requires minimal storage precautions, and offers greater convenience for farmers. The fertilizer is completely water-soluble, free of impurities, and leaves no residue. It is perfectly compatible with various application methods—ranging from traditional broadcasting, furrow application, and spot application to modern drip irrigation, sprinkler irrigation, and fertigation systems—without clogging irrigation pipelines. It is suitable for a wide variety of cultivation scenarios and fertilization equipment. Furthermore, the product possesses stable chemical properties. Compared to ordinary ammonium nitrate, its safety profile is significantly enhanced, posing no risk of flammability or explosion. During application, it releases no volatile ammonia gas and does not cause burns to crop leaves or roots. It can be safely applied in enclosed cultivation environments, such as greenhouses and polytunnels, making it a green and eco-friendly fertilizer that is beneficial to crops, soil, and the environment alike.

5. Synergistic Nutrient Effects: Significant Improvements in Quality and Yield

In Calcium Ammonium Nitrate Yellow granular, the nitrogen and calcium nutrients mutually promote and facilitate each other's absorption. Nitrogen stimulates the crop's vegetative growth, while calcium optimizes its reproductive growth. Simultaneously, the product enhances the crop's uptake and utilization efficiency of other macro- and micronutrients present in the soil—such as potassium, magnesium, zinc, and iron—thereby ensuring a balanced supply of nutrients. When applied during critical stages of crop growth, this product promotes flower bud differentiation, aids in flower and fruit retention, and increases the fruit-setting rate. It stimulates fruit enlargement and uniform coloration, enhances the content of nutrients—such as sugars, vitamins, and proteins—and improves both the flavor and visual quality of the fruit, while simultaneously reducing the proportion of malformed or substandard produce. Furthermore, it extends the harvest period as well as the post-harvest shelf life and transport durability of the produce, thereby effectively boosting both crop yield and commercial value. Field trials have verified that the judicious application of yellow Calcium Ammonium Nitrate results in a 15–30% increase in yield for fruit and vegetable crops, and a 10–20% increase for field crops, demonstrating a significant improvement in overall crop quality.
