Can albizia mulch be used on agricultural land to replace fertilizer, improve agroecosystem functioning, and provide climate change mitigation and resilience?
Project Summary: This project will investigate the potential benefits of composted albizia (Falcataria moluccana) mulch applied to agricultural land in East Hawaiʻi. The biomass from this fast-growing, nitrogen-fixing tree contains a large amount of carbon and nitrogen. A management approach that takes unwanted biomass from albizia trees and applies it to cropland could yield a net environmental and/or economic benefit compared with status quo farming practices, while stimulating albizia removal efforts. If this approach is found to be economically viable, climate change mitigation and/or resilience could be a byproduct of agricultural activities.
