End Date: Sep 30, 2014
Soil samples will be collected from different aged fumigated sites from calla lily field in Moss Landing, CA. Fumigated sites ranging in age approximately from few months to 30 years, will be selected. Non-fumigated fields will be used as a control. From each site, four transects will be identified and from each transect, soil samples will be collected from 4 different locations and 2 depths (0-5 cm and 5-15 cm). Phospholipid fatty acid (PLFA) analysis will be used to study the microbial community structure recovery for non-target organisms. Determination of Fusarium oxysporum and Pythium spp. populations will be done using dilution plating on Komada’s and P5ARP medium respectively.
