The impact of chlorine in fertilizers on plant health

Written by fertilizer production line on February 6th, 2026.

Chlorine is an essential micronutrient for plant growth. Although often overlooked, the chlorine element in fertilizers processed by fertilizer granulators can contribute to plant health by regulating physiological metabolism. The key lies in precisely matching crop needs and application rates.

Chlorine’s beneficial effects on plant health are clear. Firstly, it participates in photosynthesis, assisting in chlorophyll synthesis and photosynthetic product transport, thereby improving photosynthetic efficiency. Secondly, it regulates cell osmotic pressure, balances water content, and enhances the plant’s resistance to drought and salinity. Thirdly, it inhibits the growth of fungi and bacteria, promotes root development, and strengthens nutrient absorption.

Crops vary greatly in their tolerance to chlorine, requiring precise application. Chlorine-loving crops such as corn and rice can benefit from appropriate application of chlorine-containing fertilizers processed by rotary drum granulators, leading to improved quality and increased yield. However, chlorine-sensitive crops such as tobacco and strawberries can suffer from excessive chlorine absorption, resulting in leaf scorching and reduced fruit quality; therefore, chlorine-containing fertilizers should be avoided.

Scientific application is crucial. It is necessary to control the amount of chlorine-containing fertilizers to avoid chlorine accumulation in the soil; combining them with organic fertilizers can mitigate the irritating effects of chlorine; chlorine-sensitive crops should use chlorine-free fertilizers, while chlorine-loving crops can use chlorine-containing fertilizers in combination with nitrogen, phosphorus, and potassium fertilizers.

In summary, chlorine in chlorine-containing fertilizers is an “invisible helper” for plant health. By using standardized products processed by fertilizer granulators and applying them precisely according to crop characteristics, its value can be fully realized.

Extrusion granulation technology: Can it improve the strength and uniformity of bio-fertilizer granules?

Written by fertilizer production line on February 6th, 2026.

The answer is yes. Fertilizer extrusion granulation technology, with its controllable mechanical pressure and precise molding control, effectively addresses the problems of loose and unevenly sized bio-fertilizer granules. It is well-suited to the characteristics of bio-fertilizers containing microbial agents and complex nutrients, making it a high-quality granulation solution that balances granule quality and biological activity.

This technology ensures granule uniformity through pre-treatment and pressure control. After crushing, screening, and uniform mixing of raw materials, the mixture is fed into a fertilizer granules compaction machine. The granules are tightly bound together through roller or screw extrusion, and the particle size can be precisely controlled through equipment parameters, avoiding size variations.

The increased granule strength stems from the densification achieved during extrusion molding. The gaps between raw materials are compressed, enhancing compressive strength and reducing breakage and clumping during storage and transportation, while also preventing the loss of microbial agents. Compared to other technologies, it does not require high-temperature drying, thus protecting the survival of heat-sensitive microorganisms, balancing both strength and biological activity.

Two points need to be controlled during operation: firstly, the raw material moisture content should be controlled at 5%-8% to avoid sticking or poor molding; secondly, the extrusion pressure should be precisely controlled to suit different formulations, preventing improper pressure from damaging microorganisms or leading to loose granules.

In summary, fertilizer extrusion granulation technology can significantly improve the strength and uniformity of bio-fertilizer granules, adapting to their characteristics. It optimizes product appearance and storage stability while preserving biological activity, making it suitable for large-scale production and field application.

Preparing for bio-organic fertilizer production: 5 key steps!

Written by fertilizer production line on February 6th, 2026.

The core of bio-organic fertilizer production is ensuring thorough composting, microbial activity, and product quality. Early preparation directly determines production efficiency and requires multi-dimensional planning to avoid pitfalls and lay a solid foundation for large-scale, standardized production.

Raw material preparation is fundamental. Select organic raw materials free of pesticide residues and odors, and mix carbon sources (straw, sawdust) and nitrogen sources (livestock and poultry manure, fungal residue) at a carbon-to-nitrogen ratio of 25:1-30:1. Crush and dry the materials in advance, removing impurities. Also, prepare composting microbial agents to improve microbial decomposition efficiency.

Equipment preparation should be tailored to the scale of production. Basic bio-organic fertilizer equipment includes crushing, mixing, and turning equipment. Windrow compost turning machines are suitable for large areas and heavy materials. Large-scale production requires a complete bio-organic fertilizer production line, integrating various equipment and including molding and drying facilities. Equipment and production lines should be tested in advance to ensure smooth operation and meet the requirements for controlling fermentation parameters.

Site and technical preparation are indispensable. The site should be located away from residential areas and have good ventilation and drainage. Small-scale production can use open-air sites, while large-scale production requires factory buildings. Mastering fermentation technology is also crucial, including understanding temperature and humidity control, ventilation frequency, and developing contingency plans for abnormal situations.

Compliance preparation cannot be overlooked. Ensure compliance with environmental standards and understand local waste disposal and wastewater discharge regulations. By completing these preparations and utilizing appropriate bio-organic fertilizer equipment, windrow compost turning machines, and a standardized production line, efficient production and guaranteed product quality can be achieved.

Addressing the five core challenges of using NPK compound fertilizers

Written by fertilizer production line on February 6th, 2026.

NPK compound fertilizers have become mainstream in agricultural production due to their comprehensive nutrients and convenient application. However, they face multiple challenges influenced by formulation and application methods, which not only restrict fertilizer efficiency but may also lead to soil and environmental problems, requiring rational avoidance.

The primary challenge is the lack of adaptability due to fixed formulations. The nutrient ratio is preset by the NPK fertilizer production line and is difficult to adjust after the raw materials are mixed by the fertilizer mixer. This prevents precise matching of soil fertility and crop nutrient requirements, easily leading to nutrient imbalances and affecting crop quality.

Low nutrient utilization efficiency easily leads to imbalances. Unreasonable application can lead to nitrogen volatilization and potassium leaching, resulting in utilization rates of less than 40%; long-term single application can also disrupt soil nutrient balance, inhibit the absorption of trace elements, and induce crop nutrient deficiencies.

Environmental and soil degradation risks are prominent. Excessive application can easily cause soil compaction and acidification, and nitrogen and phosphorus runoff can lead to water eutrophication, violating the requirements for reducing fertilizer use and increasing efficiency, and causing long-term damage to arable land quality.

Quality and cost control are challenging. Inferior products result from the use of non-standard fertilizer production equipment, substandard NPK fertilizer production line processes, and failure to achieve uniform mixing through professional fertilizer mixers, leading to substandard nutrient content; high-quality products have high raw material costs, and improper application can easily increase planting costs.

In summary, the challenges of NPK compound fertilizers are concentrated in adaptability, utilization efficiency, environmental protection, and quality control. Combining precise selection based on soil testing and application with organic fertilizers can address these pain points and improve fertilizer efficiency.

Composting avoidance guide: These items should never be added to compost

Written by fertilizer production line on February 6th, 2026.

The core of composting is the beneficial decomposition of organic materials by microorganisms; not all waste is suitable for composting. Even with organic fertilizer composting equipment, improper addition of items can disrupt the compost balance, breed harmful substances, and even lead to compost ineffectiveness and soil pollution.

Kitchen Waste Prohibited: Grease, fatty meat, animal offal, and dairy products should not be added to the compost pile. These materials decompose slowly, easily clump together, and even with a compost turning machine, aeration is difficult to improve. They also easily attract flies and emit foul odors. Kitchen waste with excessive salt and sugar content will inhibit microbial activity, causing composting to stagnate and affecting fertilizer efficiency.

Chemicals and Synthetic Substances Strictly Prohibited: Non-degradable materials such as plastics and glass will leave residues in the compost, polluting the soil and potentially damaging equipment parts, clogging organic fertilizer production lines, and hindering commercial processing. Cleaning agents and pesticide residues contain chemical toxins that will kill beneficial bacteria and harm crops and human health; used batteries contain heavy metals, which will cause soil contamination.

Special organic waste. Plant residues carrying pathogens and pet feces may carry insect eggs and pathogens, which are difficult to completely kill with the high temperatures of ordinary organic fertilizer composting equipment. Even after thorough turning with a c ompost turning machine, pests and diseases can still easily spread. Mature weed seeds may not be inactivated after being added to the compost pile, leading to excessive weed growth in the field after application.

Composting must adhere to the principle of “natural organic, no harmful residues,” using only safe materials such as straw, vegetable leaves, and ordinary livestock and poultry manure to ensure compost quality and avoid secondary pollution.

Granular potassium fertilizer: A comprehensive guide to benefits, production, and application

Written by fertilizer production line on February 5th, 2026.

Granular potassium fertilizer is a commonly used, high-quality form of potassium fertilizer in agricultural production. It offers the advantages of convenient storage and transportation, and stable fertilizer efficiency. Its production relies on specialized equipment, and its application requires careful consideration of crop needs, balancing increased efficiency with soil health.

The core benefits focus on practical application and effectiveness. Compared to powdered potassium fertilizer, granular potassium fertilizer is less prone to caking and dust, making storage and handling more convenient and reducing nutrient waste; its uniform particle size is suitable for mechanized application, ensuring even distribution and preventing seedling burn, saving labor and increasing efficiency; and its slow-release properties provide a sustained supply of potassium, improving absorption and utilization.

The production process emphasizes standardization and adaptability. Granular potassium fertilizer is often produced using NPK fertilizer production lines, employing granulation machines such as double roller press granulators and rotary drum granulators. This process requires minimal binders and high-temperature drying, and is compatible with raw materials such as potassium chloride and potassium sulfate, allowing for precise control of particle strength and size.

Application must follow scientific principles. It is suitable for field crops such as corn and rice, as well as economic crops such as tomatoes and fruit trees, with a focus on application during critical potassium-demanding stages such as stem elongation and fruit development; it can be applied through furrow application or broadcasting, and combined with organic fertilizers to enhance effectiveness; and the application rate should be controlled based on soil fertility to avoid excessive application and nutrient antagonism.

In summary, the value of granular potassium fertilizer lies in its standardized production and scientific application. It leverages its physical form to improve practicality and contributes to efficient and sustainable agricultural production through precise nutrient supply.

The fastest way to increase soil nitrogen content: Read and apply directly

Written by fertilizer production line on February 5th, 2026.

Nitrogen is a core nutrient for plant growth; nitrogen deficiency in the soil leads to stunted growth and yellowing leaves. Compound fertilizers produced by NPK fertilizer production lines and high-nitrogen organic fertilizers produced by organic fertilizer production lines can both supplement nitrogen. For rapid nitrogen supplementation, prioritize fast-acting methods, considering both absorption efficiency and soil suitability.

The fastest way to supplement nitrogen is to apply fast-acting chemical nitrogen fertilizers. These fertilizers can be mass-produced through NPK fertilizer production lines and absorbed by crops within 1-7 days. Commonly used fertilizers include urea and ammonium bicarbonate. Urea has a high nitrogen content and wide applicability; it can be applied in furrows, holes, or through irrigation. Dosage control is necessary to prevent root burn.

For a balance of rapid effect and soil improvement, consider combining fast-acting fertilizers with organic fertilizers. High-nitrogen organic fertilizers (such as composted chicken manure) efficiently processed by organic fertilizer compost turning machines, combined with amino acid water-soluble fertilizers, can quickly supplement nitrogen and improve soil. This is suitable for crops and soils that are sensitive to excessive chemical fertilizer application. Water-soluble fertilizers can be applied through spraying or drip irrigation for faster absorption.

When supplementing nitrogen, note the following: First, avoid single-nutrient supplementation; consider using NPK compound fertilizers combined with phosphorus and potassium fertilizers. Second, match the fertilizer to the soil; for acidic soils, add a small amount of lime to reduce nutrient loss. Shallow tillage and covering the soil can reduce nitrogen fertilizer volatilization, and organic fertilizers fully composted by composting machines can further reduce nutrient loss.

In summary, for purely fast-acting nitrogen supplementation, choose fast-acting chemical nitrogen fertilizers from NPK fertilizer production lines. For a balance of rapid effect and soil improvement, choose a combination of “fast-acting chemical fertilizer + organic fertilizer produced by organic fertilizer production lines.” Scientific application can quickly increase nitrogen levels and ensure crop and soil health.

Composting materials guide: What you can and cannot compost!

Written by fertilizer production line on February 5th, 2026.

The core of composting is the microbial decomposition of organic materials. Material selection directly determines composting efficiency, product quality, and whether unpleasant odors are produced. The key selection criteria are “easy decomposition, harmlessness, and suitable carbon-to-nitrogen ratio.” Below is a clear list of materials that can and cannot be composted.

Compostable materials mainly consist of natural organic waste, divided into two categories: carbon-rich materials (straw, sawdust, fallen leaves) to supplement carbon elements and increase aeration; and nitrogen-rich materials (livestock manure, kitchen waste, fruit and vegetable scraps, mushroom residue) to provide nutrients and accelerate decomposition. A small amount of wood ash or composting inoculant can be added. Using an organic fertilizer composting machine for turning and mixing will improve the process. Windrow compost turning machines are suitable for large areas and heavy materials, while large wheel compost turning machines are suitable for small and medium-sized operations, helping to ensure even mixing of materials.

The following materials should absolutely not be composted: high-salt and high-fat foods (leftovers, fried foods, pickled foods), which will attract pests, produce foul odors, and inhibit microbial activity; and toxic and harmful materials (plastics, glass, straw with pesticide residues, chemical waste), which cannot be decomposed and will pollute the soil.

In addition, meat and bones decompose slowly and easily breed bacteria, so they are not recommended; large, hard objects that have not been crushed need to be crushed beforehand. After adding them, they can be turned and mixed using an organic fertilizer composting machine (both windrow and large wheel composting machines are suitable) to reduce ventilation obstruction; hazardous waste such as batteries is strictly prohibited to prevent heavy metal contamination.

In summary: Prioritize natural, easily decomposable organic waste, combine materials according to the carbon-to-nitrogen ratio, avoid prohibited materials, and use appropriate composting equipment to quickly produce high-quality, odor-free compost, contributing to soil improvement and crop growth.

Guidelines for large-scale production of bio-organic fertilizer: Key to high-efficiency mass production

Written by fertilizer production line on February 5th, 2026.

The core of large-scale bio-organic fertilizer production is achieving “resource utilization of raw materials, standardized processes, mechanized equipment, and controllable quality.” This requires relying on complete sets of equipment and scientific processes, balancing mass production efficiency and fertilizer activity. The core processes and key points are as follows:

Step 1: Raw Material Pre-treatment and Proportioning: Collect livestock and poultry manure, crop straw, and other raw materials in batches. After crushing and screening to remove impurities, the materials are precisely mixed using a double axis paddle mixer according to a carbon-nitrogen ratio of 25-30:1 and a moisture content of 55%-60%, laying a solid foundation for microbial fermentation.

Step 2: Microbial Activation and High-Temperature Fermentation: Select high-efficiency microbial strains such as Bacillus subtilis, activate and expand them, and then mix them into the raw materials. Regular turning is performed using a compost turning machine, controlling the temperature at 55-65℃ and the pH value at 6.5-7.5. Fermentation takes 7-15 days to ensure thorough decomposition, kill pathogens, and preserve microbial activity. This is the core of the production process.

Step 3: Post-treatment and Granulation: The fermented material is dried at low temperature (moisture content ≤20%), crushed, and screened. Granulation is then performed using a double roller press granulator, balancing efficiency and microbial activity while avoiding high-temperature damage.

Step 4: Testing and Storage: The finished product is tested for indicators such as organic matter and effective viable bacteria count. After meeting the standards, it is packaged and stored. Storage requires ventilation, dryness, and protection from light and moisture. The entire process relies on a complete set of bio-organic fertilizer equipment to achieve continuous mass production.

In summary, the key to large-scale production is precise raw material proportioning, controllable fermentation, and coordinated equipment, ensuring both mass production and fertilizer quality, contributing to green and circular development in agriculture.

Basic knowledge of large-scale composting on dairy farms: From raw materials to maturity

Written by fertilizer production line on February 5th, 2026.

Large-scale composting on dairy farms is a key path to the resource utilization of manure and alleviating environmental pressures. The core is the transformation of dairy cow manure into high-quality organic fertilizer through microbial fermentation.

Raw material ratio is a prerequisite for successful composting. The core raw material is fresh dairy cow manure with a moisture content of 70%-80%. It needs to be mixed with auxiliary materials such as straw and sawdust to adjust the carbon-to-nitrogen ratio and moisture content. The ideal carbon-to-nitrogen ratio is controlled at 25-35:1, and the moisture content is adjusted to 60%-65% (it should clump together when squeezed in the hand, with water seeping between the fingers without dripping). The auxiliary materials account for 30%-40%, which prevents the compost from smelling bad and provides sufficient energy for microbial activity.

The fermentation process focuses on large-scale, efficient maturation, often using windrow compost turners or trough-type compost turners. The compost pile height is 1.5-2.0 meters and the width is 3-5 meters to ensure air permeability and heat retention. Fermentation is divided into three stages: First, the temperature is raised to 55℃ for 1-3 days, then maintained at 55-65℃ for at least 3 days to kill pathogens and insect eggs. Finally, the temperature is lowered to below 40℃, allowing microorganisms to continue decomposing organic matter. Regular turning and aeration throughout the process promotes uniform composting.

Quality control and final stages determine compost quality. The maturity standard is: temperature reduced to room temperature, dark brown color, no fecal odor, and organic matter content ≥30%. After screening and impurity removal, qualified material can be directly used as core raw material in organic fertilizer production lines to process into commercial fertilizer. Material not connected to the production line must be stored in a well-ventilated and dry place to prevent moisture absorption.
