Agricultural trench depth systems, methods, and apparatus

An agricultural planting system for controlling the depth of an opener device in an agricultural planter, the agricultural planting system comprising:

• an agricultural planter;
• an opener device mounted on the agricultural planter for engaging the ground of a field;
• a gauge wheel mounted on the agricultural planter for rotating on the ground of the field;
• a GPS device coupled to the agricultural planter, the GPS device configured to determine a location of the agricultural planter in the field;
• and
• a controller in electrical communication with the agricultural planter and the GPS device, the controller having predetermined settings associated with a map of the field, the controller being configured to select a relative elevation of the opener device and the gauge wheel based at least in part on the location determined by the GPS device, and produce, based on the location, a signal for adjusting the depth of engagement into the ground of the opener device.
