Abstract

Soil moisture is critical for crop production in most years in north western Iowa. Soil moisture samples were taken at 20 sites in northwest and west central Iowa during the last few days of October 2012. Moisture samples were taken at 1-ft increments down to a 5-ft depth. Samples were weighed, oven dried, and reweighed at the ISU Northwest Research Farm. The moisture percentage was calculated from these data, and then used to calculate the inches of plant available moisture in the soil.
