Sheep manure is a high-quality organic fertilizer source, rich in various nutrients such as nitrogen, phosphorus, potassium, etc., and is very suitable for making organic fertilizers. The process flow for processing it into powdered organic fertilizer is roughly as follows:
1. Raw material preparation
Sheep manure collection: Collect fresh or slightly dried sheep manure from the pasture, paying attention to removing impurities such as stones, plastic sheets, and other non organic matter.
Pre treatment: If the moisture content of sheep manure is high, it may be necessary to use a solid-liquid separator for dehydration treatment to reduce the moisture content to about 40% to 50%.
2. Fermentation treatment
Mixed composting: Mixing sheep manure with other organic waste (such as rice straw, corn stover, legume crop residues, etc.) in a certain proportion to help regulate the carbon nitrogen ratio and initiate the fermentation process.
Inoculation strain: In order to accelerate fermentation, specialized fermentation agents such as EM bacteria, Bacillus subtilis, etc. can be added.
Pile flipping and ventilation: Regular flipping and ventilation are carried out through an organic fertilizer flipping machine to ensure sufficient oxygen supply, maintain a suitable fermentation temperature (50 ℃~60 ℃), and promote organic matter decomposition.
3. Drying
Natural drying: Spread out the fermented organic fertilizer and let it air dry naturally for a few days to further reduce the moisture content to 10% to 15%.
Alternatively, an organic fertilizer dryer can be used for manual drying, especially in adverse weather conditions, to achieve the desired moisture content more quickly.
4. Crushing
Use an organic fertilizer grinder to grind the dried organic fertilizer raw materials into finer powder for subsequent processing.
5. Mixing and sieving
Secondary mixing: If necessary, other elements (such as trace elements, biological agents, etc.) can be added for secondary mixing to ensure uniform composition.
Screening: Removing oversized or insufficiently decomposed clumps through a sieve to ensure the quality and uniformity of powdered organic fertilizer.
6. Packaging
Finally, the qualified powdered organic fertilizer can be quantitatively packaged, sealed, and stored before being sold to farms, garden centers, or directly applied to farmland.
It is worth noting that compared to granular organic fertilizers, powdered organic fertilizers are prone to dust during storage and transportation, so dust prevention should be taken into account during packaging and use. In addition, due to its lack of granulation process, it may not be as easy to spread as granular fertilizer when applied in the field, but this does not affect its effectiveness as a high-quality organic fertilizer.
Although the production of sheep manure powder organic fertilizer may seem simple, every step requires careful operation to ensure the quality of the final product. Correctly processed sheep manure organic fertilizer can not only effectively improve soil, but also increase crop yield and quality, bringing significant benefits to the planting industry.
