Zone Management Strategies for Sodic/Saline Soils

Due to water resources in Southwestern Oklahoma much of the soil has very sodic and saline problems.  These problems lead to a reduction in plant stand and fiber yield at the end of the season.  This study used a three year yield stability map to delineate zones for a precision soil sampling strategy.  Soil samples were collected from four depths, and then tested for routine, macro and micro nutrients, and a comprehensive salinity paste.  Soil Electroconductivity (EC) was collected using the Veris 3100 on the same field.  The purpose of this study is to determine the relationships between soil parameters such as the soil test results and their relation to the Veris soil EC.  The soil test results and their relationship to cotton lint yield.  The relationship of the Veris EC and cotton lint yield.  This is the beginning of a multiple year study where the end goal is to have a viable solution for cotton producers facing sodic and saline soil issues.
