Interpretive Summary: Major questions exist regarding the identification of suitable cropping system practices that can be used to produce temperate grass seed crops in the Pacific Northwest in the absence of open- field burning. All future sustainable solutions to nonthermal postharvest residue management will require that the alternative practices identified will have a minimal impact on the environment but also allow economic long-term production. This paper describes a conceptual context for viewing grass seed production systems as a part of larger regional landscapes where conflicting land-use interests place different values and demands on the use of agronomic practices to produce seeds. In addition to necessary single-factor production practice research, an integrated multidisciplinary approach is presented as a means to investigate alternative approaches to temperate grass seed production.
Technical Abstract: Major questions exist regarding the identification of sustainable cropping systems practices needed to produce perennial grass seed crops in the Pacific Northwest in the absence of open-field burning and using maximal postharvest residue management. The purpose of conducting long-term research is to implement decision management information tools that can predict the optimal sequence of temperate grass seed production practices needed for environmentally protective and economically viable production. Through the use of an integrated research approach, we are identifying strategies that account for dynamic system changes based on soil quality parameter measurements, shifts in soil microbial and faunal populations, and crop responses that result from different cropping technologies. Our integrated best management system options will utilize minimal chemical and energy inputs through the use of prescription-based pest and fertilizer management and no-till crop establishment.
