Effects of nitrogen recycling by human urine fertilization on butterfly pea (Clitoria ternatea) plant in green wall system on AIT campus

Urban Farm DB summary

This study investigated the effects of human urine as fertilizer on butterfly pea (Clitoria ternatea) plants in a green wall system on the AIT campus. Applied at a nitrogen loading rate of up to 0.73 g N m-2 week-1 (104.28 mL urine m-2 week-1) for 16 weeks, urine fertilizer positively affected the food production, inflorescences, and health of butterfly pea plants, indicating it is suitable for green walls. This method could reduce campus wastewater load and save on expensive wastewater treatment.
