Study Notes
Dealing with Plant Diseases
- Dealing with plant diseases through spraying only suppresses symptoms, but does not address the root cause.
- A healthy plant can naturally resist most diseases.
- The use of fertilizers has led to the increased use of pesticides, which has negative consequences.
Improving the Soil
- The key to healthy plant growth is improving the soil, which requires a partnership between plants, fungi, and bacteria.
- This partnership is based on trading products, with fungi and bacteria supplying nutrients and plants providing sugars in the form of glucose.
The Plant-Fungi-Bacteria System
- Fungi and bacteria supply nutrients from the soil that would be hard for plants to access.
- Plants supply sugars in the form of glucose in exchange for these nutrients.
Plant Limitations
- Plants have limited root capacity, with fine absorption roots that only use 4 to 7% of the soil volume and have a short lifespan of only one to three weeks.
Plants Need Help
- Plants need external help to overcome their limitations, and they form partnerships with fungi and bacteria to achieve this.
- If plants cannot find partners, they will die, but if they succeed, it marks the start of a beautiful symbiotic relationship.
Rhizobia Bacteria
- Rhizobia bacteria are specialized in releasing phosphate from the soil, which is essential for plant growth.
- They also carry out other important tasks, including forming a natural defense system around the roots to prevent disease-causing bacteria from entering.
- This defense system is mutually beneficial, as the plant provides the bacteria with food in return.
