Organic fertilizer equipment in the production of organic fertilizer, the control of pH value is crucial to the quality and effect of the final product. The following is the importance of pH in organic fertilizer production:
1. Affect microbial activity: pH value will directly affect the activity of microorganisms in organic fertilizers. When microorganisms decompose organic matter, their activity is most vigorous in the pH range usually in neutral or slightly alkaline environments.
2. Nutrient availability: Changes in pH value will affect the solubility and availability of nutrients in organic fertilizers. For example, phosphorus is more available at pH 6-7.5, while trace elements such as iron, manganese, zinc, and copper are less soluble in neutral to alkaline environments.
3. Plant growth: Different crops have different adaptations to soil pH. An appropriate pH range helps crops to better absorb nutrients and promote crop growth.
4. Stability of organic fertilizer: The control of pH value helps to maintain the stability of organic fertilizer and avoid nutrient loss or soil structure damage caused by too high or too low pH value.
5. Reduce the risk of pollution: Proper pH helps to reduce the activity of harmful substances in organic fertilizers, such as heavy metals and harmful microorganisms, thereby reducing the risk to the environment and human health.
6. Quality of organic fertilizer: pH value is one of the important indicators to evaluate the quality of organic fertilizer. The appropriate pH value helps to improve the quality of organic fertilizers and meet the requirements of agricultural industry standards.
In order to ensure the quality and effect of organic fertilizer, organic fertilizer production lines need to accurately control the pH value, usually by adding an appropriate amount of alkaline or acidic substances to adjust the pH value, so that it reaches the appropriate range.
