Abstract
Increasing consumer demand for organic products has created a need for
certified organic research sites. Our objective is to discuss the lessons
learned from evaluating alternate cropping systems to establish a certified
site in western Iowa.
Oat (Avena sativa L.), ‘Kelson’ snail medic [Medicago
scutelata (L.) Mill.] or ‘Polygraze’ burr medic (Medicago
polymorpha L.), triticale (xTriticosecale spp.), sweet
corn (Zea mays L.), soybean [Glycine max (L.) Merr.],
rye (Secale cereale L.), and alfalfa (Medicago sativa L.)
or red clover (Trifolium pretense L.) were evaluated in five
crop sequences as transition strategies for converting no-till corn
and soybean land for certified organic production.
Five models for managing organic research sites were developed and
are discussed to help researchers and producers become aware of the
different roles, goals, and management challenges faced when developing
a certified organic research site.
A "shared management model" (Type 3) best described our
project involving a transitioning grower and researchers. Maintaining
annual profit throughout the transition period was our most important
factor, so potential returns to land, labor, and management were calculated
to compare the various transition strategies.
Only two of the cropping systems incurred a positive return to management.
They used either a high-value crop such as sweet corn (provided it was
marketable) or low-cost crops (i.e., oat and alfalfa).
We conclude that learning from our experiences will enable others to
develop certified organic research sites and become involved with on-farm
research studies with much less stress than that encountered by our
farmer cooperator, technical staff, land owner, and research team.
