What kind of fertilizer does wood ash belong to? Which packaging machine should be chosen for wood a

Wood ash is the residue left after plants are burned and is a kind of high-quality farmyard manure with wide sources and low cost. From a scientific classification perspective, it is mainly an "organic potassium fertilizer derived from inorganic substances", but its composition and functions far exceed those of a single potassium fertilizer. Now, Zhengzhou Hanke Machinery will take you to understand the fertilizer properties of wood ash and the selection guide of packaging machines

I. Fertilizer Properties of Plant Ash

Wood ash is the residue left after plants are burned. Its main component is potassium carbonate (K₂CO₃), with a potassium content usually ranging from 6% to 12%. It also contains medium and trace elements such as phosphorus, calcium and magnesium. According to the classification standards of chemical fertilizers:

Potassium fertilizer: A type of fertilizer with potassium as its main nutrient. Wood ash, due to its significant potassium content and the absence of nitrogen and phosphorus elements, is classified as potassium fertilizer.

The difference from other fertilizers: Compound fertilizers need to contain at least two of the elements nitrogen, phosphorus and potassium, while wood ash, which only contains potassium, does not belong to compound fertilizers. Nitrogen fertilizer is mainly composed of nitrogen elements, phosphorus fertilizer is mainly composed of phosphorus elements, and plant ash does not meet the requirements.

Ii. Suggestions for the Selection of Wood Ash Fertilizer Packaging Machines

In view of the characteristics of wood ash powder (poor fluidity and easy to raise dust), it is necessary to select packaging equipment with high precision and dust-proof functions. The following types are recommended

Spiral quantitative packaging machine

Applicable scenarios: Quantitative packaging within 50kg, suitable for bulk materials such as biomass pellets, flower soil, and flower fertilizer.

Technical features

The screw feeding mechanism is adopted to solve the problem of poor fluidity.

The digital control system achieves high-precision measurement (error ≤0.2%).

The stainless steel body is corrosion-resistant and meets the demands of the food/agricultural products, agriculture, forestry, animal husbandry and fishery industries.
