- Observation Enrichment increased biochar nitrate and ammonium content, especially wood biochar with cow urine.
- Intervention effect Both biochars reduced nitrate and ammonium leaching versus urea and unamended controls.
- Intervention effect Cow urine enriched crab shell biochar reduced nitrate leaching by 85.1%.
- Intervention effect Cow urine enriched wood biochar reduced ammonium leaching by 94.8%.
- Intervention effect Cow urine enriched wood biochar reduced nitrate leaching by 87.8%.
- Intervention effect Seaweed enriched biochar reduced inorganic nitrogen leaching, less than cow urine enrichment.
- Intervention effect One gram of wood biochar increased wheat shoot length by 29.5%.
- Intervention effect Higher crab shell biochar rates reduced shoot length by 35.0%.
- Observation Cow urine enriched wood biochar and seaweed extract alone yielded the longest shoots.
- Observation Cow urine enriched wood biochar had the highest nitrogen retention.
- Observation Cow urine enriched wood biochar had the greatest stimulation of shoot growth.
