Other claims from this paper (4)
- Intervention effect Composting improved mung bean germination index from 49% to 58%–90%.
- Intervention effect Composts A and B gave watercress yields of 1663.2–1762.2 kg/1000 m2, comparable to chemical fertilizer.
- Intervention effect Composts A and B produced significantly lower watercress yield than commercial micro-organic fertilizer.
- Mechanism The authors suggest dissolved solids in compost A and heavy metals in compost B could limit root growth.
