Using Soil Electrical Conductivity

            In this day and age of farming precision agriculture is being utilized more and more during each growing season. Farmers want to grow their crops the best ways possible and they are turning to precision agriculture. One way that farmers can determine yield is by using Veris EC equipment. Today, more fields are mapped with Veris EC equipment than any other on-the-go soil mapping technology. By using soil mapping, farmers are better able to know more aspects of the soil they have been farming on for years. Soil texture relates to factors that have a major impact on productivity, such as: water holding capacity, cation-exchange-capacity (CEC), topsoil depth, and nitrogen-use efficiency. Therefore, EC maps often correlate well with crop yield maps. An EC map is a fundamental layer needed for precision action, such as guided soil sampling, yield map analysis, variable seeding, variable yield goals/N, and land-leveling. The objective of this study is to determine the relationship between yield and electrical conductivity using the Veris EC meter.
