Soil sampling in November

November 9, 2016 - Issue 29

Given the warm temperatures and moist soil conditions, the ideal time for fall soil samples may still be ahead of us.

For results to be as close as possible to the situation next spring, the ideal time to take fall samples is when soil temperatures drop below 10°C and as close to freeze-up as possible. Microbial processes in the soil slow down as temperatures cool, so mineralization should be minimal below that threshold.

With results and recommendations in hand before the ground freezes, growers can use the winter months to plan their fertilizer programs for next year, to order fertilizer, and to take advantage of pricing opportunities that may occur.
