Bio-organic fertilizers contain all essential nutrients, improve soil quality, and mitigate soil compaction caused by chemical fertilizers. They enhance soil physical and chemical properties, boost water and nutrient retention, and supply nutrients effectively. By reducing environmental pollution, these fertilizers are safe for humans, livestock, and the environment, making them an eco-friendly option.

The production materials for biological organic fertilizers are diverse and can be broadly categorized into the following types:

agricultural waste

For example, straw, soybean meal, cottonseed meal, and the like.

livestock and poultry manure

For example, chicken manure, cattle dung, sheep dung, horse dung, and rabbit dung;

domestic waste

For example, food waste and kitchen waste;

Plant products

For example, bamboo powder, bamboo charcoal, bamboo ash, straw charcoal, and plant ash

Organic Fertilizer Fermentation Production Process

1. The primary step involves mixing organic solid waste with a moisture content below 60% with auxiliary materials (such as plant straw) and microbial fermentation agents, ensuring thorough blending;

2. Through continuous aerobic fermentation by irrigation, it is thoroughly decomposed, sterilized, deodorized, and dehydrated.

3. The moisture content of the composted material typically ranges from 30% to 35%. After screening, it can be directly used for granulation production of spherical organic fertilizer or powdered organic fertilizer.

Organic Fertilizer Pellet Production Process

1. After screening the fermented organic material, it is weighed, proportioned, and mixed according to the required ratio with other components to be combined. The thoroughly mixed material is then evenly and continuously fed into the impact granulator via a speed-regulating belt conveyor for granulation.

2. The particles are polished and shaped into spherical forms by the polishing and shaping machine, then dried at low temperatures with high air volume (≤65°C) in the dryer. After cooling and screening, the finished particles are conveyed by a bucket elevator to the finished product silo. They are then measured, packaged, and stored by the computer-controlled quantitative packaging system.

3. Adding functional bacteria can produce bio-organic fertilizers, while adding nitrogen, phosphorus, and potassium (with total nutrient content below 15%) can produce organic-inorganic fertilizers.
