The impact of organic fertilizer composting on fertilizer quality is profound and comprehensive. This process can significantly change the properties of organic waste, transforming it into high-quality fertilizers that are nutrient rich, structurally sound, and easily absorbed and utilized by plants. Specifically, the fermentation of organic fertilizer compost has a direct impact on several key aspects of fertilizer quality:
Improve physical and chemical properties
Enhancing fertility: During the fermentation process, organic matter is decomposed by microorganisms, releasing more essential mineral nutrients such as nitrogen, phosphorus, and potassium for plants, thereby improving the effective fertility of fertilizers.
Improving pH value: Fermentation helps regulate the pH value, making it tend towards neutral or slightly alkaline, which is more suitable for the growth needs of most crops.
Increasing the content of humic acid: Humic acid is an important organic colloid in organic fertilizers, which can improve soil structure, enhance water retention and permeability.
biological effect
Activation of Microorganisms: The suitable conditions formed during the fermentation process of organic fertilizer composting machine promote the proliferation of beneficial microorganisms (such as nitrogen fixing bacteria, phosphorus bacteria, etc.), increase soil biodiversity, and promote the construction of rhizosphere microecological environment.
Sterilization and disinfection: High temperature fermentation effectively kills pathogens and weed seeds, reduces the occurrence of crop diseases, and provides a healthier planting environment.
Improvement of physical properties
Improving soil structure: The products of organic matter decomposition help to form stable granular structures, improve soil aeration and permeability, and reduce soil compaction.
Improving water and fertilizer retention capacity: The increase in humus enhances the soil's water holding capacity and buffering capacity, effectively reducing the hazards of drought and salinization.
Chemical stability and safety
Reducing the risk of heavy metals: Heavy metal ions that may exist in certain organic materials bind to organic complexes through chelation during fermentation, reducing their toxicity.
Reduce salt accumulation: By effectively managing water and fermentation conditions, excessive salt concentration can be prevented, avoiding damage to crops.
In short, the fermentation of organic fertilizer compost can not only improve the nutritional value of the fertilizer itself, but also improve the soil structure and enhance the biological activity of the soil, thereby comprehensively improving the overall quality of the soil and creating a more favorable environment for plant growth. This approach embodies the concept of "turning waste into treasure", promotes the recycling of resources, and is an important component of modern agricultural sustainable development strategy.
