Environment Abstracts (formerly Environment Abstracts published by LexisNexis) encompasses all aspects of the impact of people and technology on the environment and the effectiveness of remedial policies and technologies. As of 1994, the database also provides expanded coverage of energy-related issues.

Environment Abstracts provides access to more than 950 journals published in the U.S. and abroad. The database also covers conference papers and proceedings, special reports from international agencies, non-governmental organizations, universities, associations and private corporations. Other materials selectively indexed include significant monographs, government studies and newsletters.

Environment Abstracts customers will also receive access to Sustainability Science Abstracts and EIS: Digests of Environmental Impact Statements.

AB:	Abstract: Albizia lebbeck, Senna siamea, S. corymbosa, Leucaena leucocephala, and Giricidia sepium were compared in terms of the nitrogen contribution to maize yield in Ibadan, Nigeria. The decomposition rate of the prunings was also monitored, and the coppicing tolerance of A. lebbeck and S. corymbosa was compared. The data showed that the N contribution of the pruning residues to maize yield above the control in A. lebbeck, G. sepium, and L. leucocephala plots was over 50%, which was high enough to justify their use in alley cropping systems. The same results were not found for the other two species, which were non-N-fixers. The N use efficiencies ranged from 49% for G. sepium to 59% for A. lebbeck. Senna siamea plots had the least weed biomass, while G. sepium and L. leucocephala had the most.
