Soil fertility decline, a major problem in many parts of the tropical and subtropical world, can be treated with relatively cheap and available organic materials such as legume cover crops, tree prunings, green manures, cattle manure, and crop residues. To compile and synthesize the large amount of "hard-to-get" information on the usefulness of such materials, the Organic Resource Database (ORD) was set up as a collaborative project in 1995 by the Tropical Soil Biology and Fertility Programme (Kenya), the Imperial College at Wye (formerly Wye College), University of London, UK, and the KARI-Muguga Soil Chemistry Laboratory (Kenya). The ORD database now contains more than 2150 records, covering data on quality parameters for at least 32 plant families, of which 1585 records refer to legumes. Recent contributors to the database include CIAT (Latin America), the International Board for Soil Research and Management (Southeast Asia), and other collaborative projects in eastern and southern Africa. So far the main plant species covered in the database have been tropical legumes. Species have been identified at the accession/cultivar level where available. Plant materials are separated into the different plant components-leaves, stems, whole shoots, roots-which accounts for much of the variation found among data of the same species. To provide a fair basis of comparisons between different datasets, methods for several key quality parameters, like polyphenols, are given. Each entry gives full credit to the origin by giving the reference from where the data have been obtained. The database is aimed at researchers, extensionists, NGO's and ultimately farmers.
