Implements and application units for placement of applications with respect to agricultural plants of agricultural fields

An application unit comprising:

• a downwardly extending elongated frame to be positioned in operation between first and second rows of plants;
• a first plant contacting member being pivotally connected and directly attached to the downwardly extending elongated frame in operation such that the first plant contacting member to be deflected rearwardly with respect to a direction of motion of the downwardly extending elongated frame upon the first plant contacting member contacting at least one of the plants of the first row of plants which causes a first change in orientation of the first plant contacting member with respect to the downwardly extending elongated frame;
• and
• a first outlet being disposed to apply a fluid application to the first row of plants with the first outlet being mechanically linked to the first plant contacting member, wherein the first change in orientation of the first plant contacting member with respect to the downwardly extending elongated frame causes a corresponding second change in orientation of the first outlet with respect to the downwardly extending elongated frame due to the first outlet being mechanically linked to the first plant contacting member,
• wherein the downwardly extending elongated frame further comprises a ground engaging element directly attached to a lower end of the downwardly extending elongated frame and disposed to contact the ground during operation.
