<p> <strong>A. Chemistry and Bioavailability of Organic Amendments to Tropical Soils</strong></p> <p> <em>1. </em><em>Potential Use of Bio-residuals on Agricultural Lands</em>. Investigate the interactions between sewage sludge, animal manures, and composts, and soil minerals, the mechanism(s) for Mn phytotoxicity induced by organic amendments, and the long-term effects of bio-residuals on soil properties and plant nutrition. Optimize the composting process of yardwaste and sewage sludge; devise methods to predict compost stability/maturity.</p> <p> <em>2. Improving Soil Productivity through Organic Amendments</em>. Study the possibility of using green manures, animal wastes and composts to reduce Al phytotoxicity and to increase P availability; identify compounds responsible for these effects and the mechanism(s) of Al detoxification by organic molecules.</p> <p> <strong>B. Nutritional Requirements for Crops and Fertility Status of Soils in Hawaii</strong></p> <p> <em>1. Coffee, Guava and Macadamia Nutrition</em>. Investigate the problem of P-induced Fe chlorosis in macadamia; study B requirements and effects of soil acidity/salinity on macadamia growth, S requirements for coffee and guava. Calcium and Zn requirements in coffee. Predict nutritional requirements for coffee, guava and macadamia through DRIS analysis.</p> <p> <em>2. Aluminum, Boron, Phosphate and Sulfur Chemistry of Hawaii Soils</em>. Determine lime requirements for many acid Hawaiian soils. Investigate the adsorption and availability of B, P and S in Hawaii soils as affected by organic matter content, surface charge (mineralogy) and rainfall patterns.</p> <p> 3. <em>Phytoremediation</em> of heavy metals (arsenic and lead) in soils and sediments in Hawaii.</p>
