What is Integrated Water and Fertilizer Management? Integrated water and fertilizer management is a modern agricultural technology that dissolves fertilizer in irrigation water and uses drip irrigation, sprinkler irrigation, and other systems to achieve “synchronous and precise supply of water and fertilizer.” It changes the traditional extensive “large-scale water and fertilizer” model, allowing...
Organic fertilizer production operates in a harsh environment characterized by high temperature, high humidity, and highly corrosive gases (ammonia, hydrogen sulfide, organic acids). Without effective protection, the steel structure of the equipment will severely corrode within 1-2 years, leading to problems such as breakage of the compost turner’s main shaft, peeling of the granulator’s inner...
In large-scale livestock farms, centralized straw processing areas, or municipal sludge composting sites, composting operations are often conducted in open, unpaved outdoor environments. In these situations, crawler type compost turners, with their excellent terrain adaptability, high processing efficiency, and economical fuel economy, become the ideal choice for windlass composting. This...
BB fertilizer is made by directly mixing various granular raw materials with different particle sizes and densities. The biggest quality challenge is component segregation. Vibration during transportation and packaging causes large particles to float and small particles to sink, resulting in uneven nutrient distribution within the same bag of fertilizer. Solving this problem requires more than...
In the production of high-concentration NPK compound fertilizer (total nutrients ≥45%), the choice of granulation process directly affects product quality, production costs, and return on investment. Currently, the two main technical routes—roller granulation (double roller extrusion granulator) and drum granulation (rotary drum granulator)—differ significantly in principle, energy consumption...
In fertilizer granulation production, a key parameter directly determines the efficiency and energy consumption of the production line—the recycled material ratio. Understanding and optimizing it is one of the core means of reducing operating costs. Definition and Calculation Formula of Recycled Material Ratio The recycled material ratio refers to the ratio of the amount of material (including...
The essence of organic fertilizer fermentation is the decomposition of organic matter by aerobic microorganisms. The C/N ratio, moisture content, and oxygen supply are the three most critical physicochemical parameters, interconnected and indispensable. Mastering their optimal ranges, mechanical intervention methods, and sensory judgment techniques is fundamental to producing high-quality organic...
In organic fertilizer production, high-moisture materials (35%-45% moisture content) have always been a major challenge in granulation. Traditional extrusion or disc granulation requires moisture content below 30%, otherwise the granules are loose, easily stick to the walls, and drying energy consumption increases dramatically. In recent years, new organic fertilizer granulators based on...
NPK 20-10-15 is a high-nitrogen, medium-phosphorus, and medium-potassium compound fertilizer formula, with a total nutrient content of 45%. This formula has a significantly higher nitrogen content than phosphorus and potassium, making it particularly suitable for leafy vegetables, corn, rice, and other crops with high nitrogen requirements. Due to its high nitrogen content and urea as the...
In the competitive organic fertilizer market, granule appearance often determines the first impression. Smooth, rounded granules not only look better and are easier to spread, but also reduce powdering during transport. The rounding machine is the core equipment for achieving this “beautifying” effect. This article analyzes how to produce pearl-like fertilizer granules from three...
