Abstract
The climate of Majuro Atoll is stable, and the soil is coral sand which has low levels of organic matter and nutrients and high percolation rates. This relatively stress-free climate and simple soil environment provides ideal conditions for the study of organic material application methods. In this study, I examined the efficiency of organic material application methods in five experiments using sweet corn crops. I obtained the following results: 1) Biomass output was correlated with residue input; however, input/output ratios converged to 0.5 at 15 Mg ha-1 a year (3 Mg ha-1 per crop). 2) The most efficient residue application rate was 2–3 Mg dry matter ha-1 crop-1. 3) In terms of organic material application methods, scattering was the most effective, followed by incorporation. Cutting, short-term fermenting, mulching, and crop bed were not effective because of the areas humid climate and low levels of soil organic matter.
