New 2002 Steep Projects

STEEP (Solutions To Environmental and Economic Problems) is a cooperative Pacific Northwest research and educational program on conservation tillage systems through the University of Idaho, Oregon State University, Washington State University, and USDA-Agricultural Research Service. It has been a national model for multi-state, multidisciplinary efforts among land grant universities, USDA-agencies, grower commodity organizations, conservation districts, and other Ag support groups and agencies to work collectively to solve regional environmental and economic problems. Funding has been provided by special Congressional grants through USDA since 1975.

The STEEP program is managed through three committees. These include: 1) a 10-member Technical Coordinating Committee of scientists from the three universities and USDA-ARS; 2) a 7-member Industry Advisory Committee of 2 growers from each state representing the grain producer and conservation district associations, and one from the pulse crop industry; and 3) an 8-member Administrative Committee representing research and extension at the 3 universities, the USDA-ARS and USDA-NRCS.

Each year, the STEEP program invites proposals on research and education projects on cropping systems technologies for direct seeding and other conservation tillage systems. Projects can be funded for 3 years with the possibility of continuing funding in the future. This longer-term funding has been critical for conducting cropping systems research projects. Sixteen research proposals were received for the 2002 funding cycle, totaling over $1,187,344. Ten proposals were selected for a total of $549,993.

The following is a listing of the new STEEP project titles (and durations and awards), investigators, and objectives of each project.

Title: Rotation Effects of Alternative Crops on Spring and Winter Wheat in Direct-Seed Cropping Systems (3 year project; $137,210)

Team: R. James Cook, WSU (crop management and supervision of farm management; Rich Allredge, WSU (statistical analyses), Bruce Frazier, WSU (remote sensing and landscape database management); Rob Gallagher, WSU (assessment of wild oat and other weeds); Dave Huggins, USDA-ARS (assessment of yield-protein relationships and soil water and nitrogen); Tim Paulitz, USDA-ARS (assessment of root diseases and soilborne pathogen); Greg Schwab, WSU (soil fertility and extension/outreach); Doug Young, WSU (agricultural economics); and Joe Yenish, WSU (extension weed scientist).

Statement of Problem to be Addressed: This project will: (1) assess the crop performance (.e.g. yield and grain protein) within rotations designed for direct-seed conditions in both a) field-scale replicated plots (PCFS), and b) across spatially diverse landscapes (CAF); (2) evaluate performance limiting or enhancing biotic and abiotic factors that contribute to rotational effects of alternative crops on subsequent direct-seed wheat with no burning; and (3) determine the economic feasibility of the different rotations on both field and within-field scales. The crop performance-limiting or enhancing factors will include the assessment of some major problems associated with continuous direct seeding, namely: stand establishment, grain yield and quality, water and N availability and use efficiency, wild oat population dynamics, soilborne root disease (Rhizoctonia, Pythium and Fusarium root rots and take-all of wheat and barley) and economic considerations. Baseline spatial data at the CAF exists for all of these variables and therefore crop rotation effects will primarily be assessed at the CAF.
