Effects of biochar on plant growth and crop productivity.
| Plant Effect | Observed Biochar Benefit | Mechanism or Interaction |
|---|---|---|
| Nutrient Uptake | Enhanced uptake of N, P, K, and micronutrients | Improved nutrient availability and retention |
| Root Development | Better root penetration and architecture | Improved soil structure and reduced compaction |
| Stress Tolerance | Increased drought and salinity tolerance | Improved water retention and root-zone buffering capacity |
| Crop Yield | Increased yield in many cases (varies by crop and soil) | Nutrient synergy with organic fertilizers and enhanced soil health |
| Disease Resistance | Reduced incidence of soilborne pathogens | Microbial competition and pathogen suppression |
| Germination and Early Growth | Improved seedling establishment | Better moisture and nutrient availability |
