A comparison of field performance of nitrogen fixing trees (NFTs) in Guam determined that biomass production was greatly influenced by soil types and plant species. The plants in the study included Acacia angustissuma, Cajanus cajan, Calliandra calothyrsus, Desmodium rensonii, Gliricidia sepium, Flemingia macrophylla, Leucaena leucocephala cv. K636, and Sesbania sesban cv. Nubica. Leucaena leucocephala was the most adapted NFT to calcareous soil, a dominant soil type in northern Guam. Flemingia macrophylla was adapted to acidic soil. Video and pamphlets on plant propagation and management were produced and distributed to the community in Guam and the Commonwealth of Northern Mariana Islands.
