Using Apparent Soil EC to Establish Management Zones in Cotton Cropping Systems

Numerous companies offer a service to producers to collect electrical conductivity using the Veris machine and then identify management zones based on the EC ratings.  Some companies are making fertilizer recommendations based on these EC zones and promoting this approach as an economic benefit.  The objective of this research was to determine the benefits and limitations to the established management zones based on the soil EC measurements.  Ultimately, the goal is determine if an economic benefit exists for the producers purchasing this service.
