Soil Improvement Applications

The application of biomass pyrolysis products in agriculture is primarily reflected in soil improvement, crop production, and pest control. Multiple studies indicate that biochar produced from biomass pyrolysis can be used as a soil amendment. It improves soil structure, water-holding capacity, water retention, aeration, enhances soil fertility, increases soil carbon content, and promotes plant growth. Biochar also provides a habitat for beneficial microorganisms, helping to inhibit plant diseases and pests.

Crop Production Applications

Enhancing Crop Yield and Quality

The addition of biomass pyrolysis char and related materials can significantly improve crop yield and productivity, enhancing nutrient uptake by crops. Using biochar as a soil amendment reduces the demand for chemical fertilizers. Biochar improves the utilization efficiency of nutrients such as nitrogen, phosphorus, and potassium, thereby reducing fertilizer usage. Studies show that combining biochar with fertilizers can cut fertilizer use by 20-30 % without affecting crop yields.

Pest and Disease Control Applications

Mechanisms of action:

1. Biochar promotes the growth of beneficial microorganisms (e.g., mycorrhizal fungi, azotobacteria) while inhibiting the proliferation of pathogens.

2. Certain compounds in biochar can trigger systemic resistance in plants, strengthening their defense against pathogens.

3. Certain compounds in biochar can trigger systemic resistance in plants, strengthening their defense against pathogens.
