When granulating pig manure fertilizers in organic fertilizer granulators in different regions, factors such as local climate conditions, soil types, crop planting characteristics, and environmental regulations should be considered. Here are some suggestions:
Climate conditions:
In areas with humid climate, dry granulation or semi dry granulation should be prioritized to reduce nutrient loss caused by high humidity and avoid compaction of soil by excessively wet fertilizers.
In arid areas, wet granulation of organic fertilizer granulators can help maintain the moisture content of fertilizers and prolong the release time of fertilizer efficiency. However, attention should be paid to controlling the moisture content reasonably to avoid affecting the storage and transportation of fertilizers due to excessive moisture.
Soil type:
For poorly drained clay soils, dry granulation methods that can provide faster fertilizer release should be selected to avoid soil salinization caused by excessive nutrient accumulation.
For well drained sandy soil, wet granulation can be used to fully utilize the nutrients in pig manure fertilizers while reducing nutrient loss.
Crop planting characteristics:
For vegetables and crops that require rapid growth, dry granulation should be chosen to meet their rapid nutrient absorption needs.
For long-term crops and fruit trees, wet granulation is more suitable because it can provide a long-lasting and stable supply of nutrients, which helps with the long-term growth of crops.
Environmental regulations:
In areas with strict restrictions on pollutant emissions, priority should be given to using environmentally friendly organic fertilizer granulation processes, such as combining biological fermentation technology with dry granulation, to reduce the generation of wastewater and waste gas.
For areas with specific environmental requirements, granulation processes that comply with local environmental standards should be adopted, and corresponding pollution control measures should be taken.
Resource recycling and utilization:
Encourage the use of pig manure resource utilization technology, such as anaerobic fermentation to produce biogas that can be used for energy recovery, reducing dependence on fossil fuels.
After appropriate pretreatment, pig manure can be used to produce organic fertilizers and achieve resource recycling.
Technical training and guidance:
Provide necessary technical support and training to help farmers master advanced pig manure fertilizer granulation technology and ensure its correct application in agricultural production.
Promote scientific fertilization methods, such as formula fertilization and precision fertilization, to improve the efficiency of pig manure fertilizer use and crop yield.
Through the above measures, it can be ensured that the granulation treatment of pig manure fertilizer is applied reasonably in different regions, which can effectively improve the utilization rate of pig manure fertilizer and protect the local environment.
