Fermented Bio-Organic Fertilizer Improves Greenhouse Environment
Vegetable greenhouses create a closed environment with high temperature and humidity, which makes them prone to various diseases and pests. As a result, farmers often use large amounts of pesticides. However, due to the poor air circulation in greenhouses, these chemicals do not disperse easily, and they are not washed away by rain or dew. This leads to slow dissolution of pesticides, which can accumulate over time. Additionally, soil salinity becomes a serious issue in such environments.
To address these problems, greenhouse waste—such as discarded vegetables, leftover plant material after harvest, and unused fruits—can be transformed into valuable bio-organic fertilizer. By mixing this waste with a small amount of greenhouse soil and some livestock manure, along with a microbial fermentation agent, it typically takes only 4 to 7 days to produce a nutrient-rich organic fertilizer. Using this as a base fertilizer helps reduce pest and disease issues in crops. It also effectively retains nutrients in the soil, prevents nutrient loss, improves soil structure, and reduces compaction and salinization.
Ms. Wang from Beijing's Changping district conducted a small experiment in her greenhouse while still skeptical about the benefits of bio-fermentation. She used a bio-fermentation agent to turn her own chicken manure into organic fertilizer. The results were impressive. Compared to directly applying raw chicken manure, the cucumbers grown with the fermented fertilizer had younger, thicker leaves, straighter fruits, longer harvesting periods, and fewer diseases. This experience convinced Ms. Wang of the power of biological fermentation, and she now fully relies on it for her greenhouse farming.
