In today’s growing emphasis on organic agriculture, mastering scientific organic fertilizer fermentation techniques and application methods is crucial for improving crop yield and quality. Every step, from fermentation turning to field application, requires precise control.

Fermentation Turning: Core Technology of Aerobic Fermentation

Turning operations are a critical link in the aerobic fermentation process of organic fertilizer, directly affecting fermentation efficiency and final product quality. Modern organic fertilizer production mainly uses professional equipment such as trough turners, wheeled turners, and chain plate turners, which can efficiently complete material mixing and aeration. The timing of turning is particularly important – the first turning occurs on the third day after the pile temperature reaches 55°C during the heating phase, every 2-3 days during the high-temperature phase, and extended to 5-7 days during the cooling maturation phase. Proper turning operation requires turning bottom materials to the top and edge materials to the center, ensuring all materials evenly contact oxygen.

Turning is not just simple material mixing, but precise regulation of the fermentation process. Through timely turning, the optimal temperature range of 55-65°C can be effectively maintained, avoiding local anaerobic environments that produce odors, while promoting complete decomposition of organic matter.

Scientific Application: Site-Specific Fertilization Strategies

Organic fertilizer application requires developing personalized plans based on crop type, soil conditions, and growth stages. Base fertilizer application should be done before sowing or transplanting, with organic fertilizer evenly spread and deep plowed 20-30 centimeters to fully mix with soil. Top dressing should be applied during key crop growth periods, supplementing nutrients through trenching or hole application. For facility agriculture, fertigation or drip irrigation methods can be used, applying dissolved organic fertilizer through irrigation systems. Foliar spraying is suitable for crop seedling and flowering/fruiting stages, enabling rapid nutrient supplementation.

Storage Management: Key to Maintaining Fertilizer Efficiency

Proper storage methods are crucial for maintaining organic fertilizer efficiency. Factory storage requires ensuring dry and ventilated warehouses, with moisture-proof pads laid on the ground, stacking height not exceeding 10 layers, and sufficient ventilation spacing reserved. For small-scale farmer storage, well-sealed packaging should be selected and placed in dry, ventilated areas, avoiding rain and direct sunlight. Both factories and farmers should follow the first-in-first-out principle and use within the shelf life to ensure fertilizer effectiveness.

The scientific use of organic fertilizer is a systematic project, from fermentation production to field application, and then to storage management, each link requires professional knowledge and careful operation. Only by comprehensively mastering these technical points can organic fertilizer fully play its role in improving soil and enhancing crop quality, achieving sustainable agricultural development.

Integrated Systems for Modern Organic Fertilizer Production

The scientific application of organic fertilizers begins with efficient production systems. Modern organic fertilizer production line operations integrate advanced organic fertilizer fermentation equipment including the chain compost turner and large wheel compost turner to optimize the aerobic decomposition process. These specialized turning machines ensure proper aeration and temperature control during fermentation, which is fundamental for producing high-quality organic amendments.

In the field of organic waste treatment, selecting the appropriate compost turner is crucial for efficiently producing high-quality organic fertilizer. Proper equipment selection not only enhances work efficiency but also significantly improves compost quality and extends equipment service life. This article provides comprehensive selection guidance based on material characteristics, processing scale, and application scenarios.

Material Characteristics Determine Equipment Selection

Material moisture content is the primary consideration in equipment selection. For materials with ideal moisture content between 55-65%, all types of compost turners can perform well. However, when handling viscous materials with moisture content exceeding 70%, crawler-type turners become the best choice due to their excellent anti-sinking and anti-adhesion design. Conversely, when processing dry, loose materials, self-propelled equipment with dust covers can effectively control dust issues.

Material particle size and composition are equally important. When processing unshredded straw or caked manure, trough-type turners with strong crushing capabilities are required. Materials containing large amounts of impurities need self-propelled equipment that is easy to clean and maintain. For high-fiber materials, the anti-winding design of spiral turners ensures continuous and stable operation.

Matching Processing Scale with Equipment Power

Material density and daily processing capacity directly determine the required equipment power. Small livestock farms processing loose straw materials can meet their needs with 50-80 horsepower self-propelled turners. Large organic fertilizer plants processing high-density mixed materials require 150-200 horsepower large trough-type turners to ensure production efficiency.

Particular attention should be paid to handling corrosive or high-viscosity materials. In addition to selecting the appropriate equipment type, corrosion resistance of materials and anti-adhesion design must be considered. Stainless steel materials and special coatings can significantly extend equipment service life under harsh working conditions.

Scenario-based Selection Case Analysis

For small to medium-sized livestock farms, self-propelled wheeled turners are ideal due to their mobility and operational simplicity. This equipment can adapt to the working environment of open composting sites, with a single operator capable of completing daily processing tasks of 150-300 cubic meters.

Large-scale organic fertilizer plants are more suitable for trough-type turners. This equipment can form a complete production line with fermentation tanks and spray systems, achieving daily processing capacity of 800-1000 cubic meters, ensuring stability in large-scale continuous production. Environmental treatment stations dealing with high-moisture, high-viscosity food waste and sludge benefit significantly from the anti-sinking and anti-adhesion characteristics of crawler turners.

Selection Considerations

During equipment selection, avoid the situation of “using small equipment for heavy tasks.” When material density is high and moisture content is elevated, choose equipment with 10-20% power redundancy to prevent overload. Simultaneously, site conditions are important considerations – open sites require highly mobile equipment, while fixed production lines prioritize stability.

The durability and maintenance convenience of wear parts should not be overlooked. When materials contain impurities or are corrosive, selecting equipment with replaceable wear parts and corrosion-resistant materials can significantly reduce long-term operating costs. Additionally, auxiliary equipment functions such as spray systems and drainage devices should be considered according to specific material characteristics.

Comprehensive Benefits of Scientific Selection

Through scientific equipment selection, not only can the fermentation cycle be shortened by 30-50%, but the humus content of organic fertilizer can also be increased by 15-20%. Proper equipment selection ensures the uniformity and efficiency of turning operations, laying a solid foundation for producing high-quality organic fertilizer. Meanwhile, well-matched equipment and working conditions can significantly extend equipment service life, reduce maintenance costs, and achieve dual improvement in economic and environmental benefits.

With the continuous development of composting technology, equipment manufacturers are constantly optimizing product designs. In the future, intelligent and automated turning equipment will further enhance the precision and efficiency of compost production, providing more powerful technical support for global organic waste resource utilization

For materials with different characteristics, the design and configuration of bucket elevators require corresponding adjustments. Block materials like ores and coal need deep or shallow buckets, which effectively prevent material fall during lifting. Meanwhile, equipment operating speed needs appropriate control to ensure materials remain stable in the buckets.

Transporting granular materials requires consideration of different factors. Medium-sized materials like fertilizer granules and plastic pellets suit medium-depth buckets, achieving good balance between conveying efficiency and material stability. Equipment operating parameters need precise adjustment based on material particle size, humidity, and flowability.

Powdered materials pose the highest requirements for bucket elevators. Fine powders like cement and flour easily generate dust, necessitating excellent sealing performance. Belt-type bucket elevators with efficient dust control devices can effectively control dust diffusion, protect the working environment, and reduce material loss.

With continuous development of industrial technology, bucket elevator applications across various industries are continuously expanding and deepening. Modern bucket elevators not only focus on lifting efficiency and reliability but have also made significant progress in intelligent control, energy conservation, and environmental protection.
