Have you encountered these problems: The soil in your vegetable garden is becoming increasingly hard and prone to clumping? Even after applying fertilizer, the vegetable leaves still easily turn yellow, and there seem to be fewer earthworms in the soil? Actually, the air contains about 78% nitrogen, and the "rhizobium" in the roots of legumes is a natural medium that converts atmospheric nitrogen into ammonium nitrogen, which plants can directly absorb. This video introduces five nitrogen-fixing companion plants commonly used by farmers (seeds can be purchased at farmers' markets or supermarkets), and provides a detailed analysis of the nitrogen fixation capacity, planting distance, and optimal timing for turning in green manure for each plant. We have also compiled a "90-Day Soil Improvement Practical Plan," providing concrete and feasible steps from soil diagnosis, microbial inoculation, intercropping management to tilling and returning the soil to the soil. We hope this will help you improve soil activity and restore a healthy vegetable garden ecosystem. 🌱 Key points of this video: Why does excessive use of chemical fertilizers make the soil more prone to compaction?
