Agricultural implement with sensors for measuring soil properties

In combination, a planter row unit and a soil sensor, comprising:

• the planter row unit comprising an opener assembly for creating a seed furrow;
• and
• the soil sensor comprising at least one flexible tine arranged behind said opener assembly, said flexible tine comprising a lower end that contacts soil in or adjacent to the seed furrow behind said opener assembly for measuring soil EC;
• wherein said at least one flexible tine is electrically coupled as an electrode in an array of electrodes for measuring soil EC;
• and
• wherein said at least one flexible tine is mounted through an electrically isolated support structure configured to electrically isolate said at least one flexible tine from a metal structure of the planter row unit.

A row crop implement comprising:

• first and second row units attached to a tool bar, each row unit comprising at least one soil engaging tool and at least one soil sensor;
• said soil sensor comprising at least one flexible tine arranged behind said soil engaging tool, said flexible tine comprising a lower end that contacts soil exposed by said soil engaging tool for measuring soil EC;
• wherein said at least one flexible tine is electrically coupled as an electrode in an array of electrodes for measuring soil EC;
• and
• wherein said at least one flexible tine is mounted through an electrically isolated support structure configured to electrically isolate said at least one flexible tine from a metal structure of the row crop implement.
