During operation of a planter implement having at least one coulter disc, an adjustable ploughshare, a seed dispensing device, and first and second furrow closing discs disposed along a common chassis, an improved process for covering seed with soil having a set moisture content, comprising the steps of:

  • associating a soil moisture content setting for germinating seed with a reference soil conductivity;

    loosening soil to an adjustable depth with said at least one coulter disc to provide exposed soil for planting seed;

    creating a furrow to a preset planting depth with said ploughshare and planting said seed in said furrow;

    measuring the conductivity of said soil between said first and second furrow closing discs;

    controlling said adjustable depth corresponding to said reference soil conductivity; and

    covering seed planted in said furrow with exposed soil from said loosening step having said set moisture content.
