Organic Fertilizer

Organic fertilizer is a type of fertilizer derived from plants or animals, primarily used to provide plant nutrition while improving the physical, chemical, and biological properties of the soil. Organic fertilizers are typically produced through the fermentation and decomposition of plant and animal residues, such as livestock manure, crop straw, and kitchen waste. There are various types of organic fertilizers, including farmyard manure(chicken manure/cow dung/pig waste), green manure, compost, humus fertilizer, and bio-organic fertilizer.

Advantages of organic fertilizer production line

Comprehensive nutrients: Organic fertilizers contain a variety of trace elements and essential nutrients.

Slow-release of nutrients: Nutrients in organic fertilizers are released slowly, providing long-term absorption for plants.

Soil improvement: Organic matter enhances the water and nutrient retention capacity of the soil, improves soil structure, and increases soil aeration and moisture-holding capacity.

Increase biodiversity: Organic fertilizers increase the microbial diversity and population in the soil, which helps suppress diseases.

Reduce the use of chemical fertilizers: Organic fertilizers contribute to sustainable environmental practices.

The production process of organic fertilizer typically includes the following steps:

Raw material collection : Suitable raw materials for organic fertilizer production (e.g., chicken manure, cow manure, pig manure), such as animal and plant residues, agricultural waste, and household kitchen waste, are collected. These raw materials are rich in organic matter and are a good source of organic fertilizer.

Pretreatment : The raw materials are crushed, mixed, and moisture-adjusted to achieve a physical state and environment suitable for microbial growth and reproduction. Microorganisms are sometimes added to promote the decomposition and conversion of organic matter.

Fermentation : The pretreated raw materials are piled for aerobic or anaerobic fermentation. Under appropriate temperature, humidity, and pH conditions, microorganisms decompose the organic matter, generating heat, releasing carbon dioxide and ammonia, and converting them into rich nutrients. Compost turning machines are typically used during the fermentation process.

Maturation : After fermentation, the materials undergo a fertilization process to remove harmful substances, improve the stability of the fertilizer, and make it more suitable for plant absorption.

Sieving and granulation : The matured materials are screened to remove large particles and incompletely decomposed matter. The materials are then granulated into uniform granules for easy application and transportation. Disc granulation and drum granulation lines are commonly used.

Drying and Cooling : The granulated organic fertilizer is dried and cooled to reduce its moisture content and improve storage stability.

Coating : Qualified granules are then treated with additives such as conditioners or color changes.

Packaging and Storage : Finally, the cooled organic fertilizer is packaged and stored for transportation and distribution.

The above steps outline the general process for organic fertilizer production line, but some adjustments and optimizations may be required depending on specific circumstances and requirements. VEST’s design team can provide you with a satisfactory solution.
