Project Type: Grant

Start Date: Sep 05, 2006
End Date: Sep 30, 2009

Objective:
1. Determine foliar iron levels and confirm Fe deficiency in the fields with high soil pH. 2. Develop solutions to overcome leaf chlorosis due to iron deficiency in blueberries.

Approach:
We will select five blueberry fields exhibiting Fe deficiencies and having high soil pHs in the North Willamette Valley. Leaf samples will be taking after bloom from newly developed shoots and whips (if present). Treatments will be arranged in a randomized complete block design with 5 replications. Subsequent leaf sampling will be taken every 4 weeks after applying treatment. All leaf samples will be analyzed for Fe and chlorophyll. Plant leaf color, growth, and leaf photosynthesis will be determined in corresponding to leaf sampling throughout the growing season. Documents Grant with Oregon State University.
