The third annual Leopold Center for Sustainable
Agriculture Center Progress Report, which provides
information on a wide array of projects, has just been
released. It offers specifics on a broad array of projects
completed during 1993.
This publication summarizes goals, methods, findings,
and implications of 21 recently completed competitive
grant projects. This year's volume highlights
results of several education and demonstration projects,
water quality work, and pest management research. It also
describes research on tillage, crops and soils, agroforestry,
and livestock.
These summaries are designed primarily for use by
agriculture in Extension and other organizations, as well as
for policymakers, for educators, and for scientists interested
in work outside their own disciplines. The semi-technical
style of these summaries is suitable for a broad audience.
Each project is outlined in four pages. (As always, copies
of the full technical reports are available on request.)
If you would like a copy of the third annual Progress
Report, or to receive copies of the first and second volumes
of the Center Progress Report, issued in 1992 and 1993,
please reply to: leocenter@iastate.edu. A full listing of
research contained in Vol. 3 is included here.
