United States Department of Agriculture Natural Resources Conservation Service Attachment C-1 Plant Management Enhancement Activity – EPL45 – Improve plant health and vigor by utilizing a minimum 28” drop line to evenly distribute taps along each tree trunk. EPL45 -28 – Inch Drop Line The Conservation Security Program (CSP) offers a new enhancement activity opportunity to reward or encourage the increased health and vigor of plants by utilizing a minimum 28-inch drop line to evenly distribute taps along each tree trunk. Improve plant health and vigor by utilizing a minimum 28" drop line to evenly distribute taps along each tree trunk . Payment equals $20.00/ac Benefits: Drop lines are the permanent, vertical tubing that connects the spout (or tap) to the horizontal tubing, which carries the sap (either by gravity or vacuum) to the sugar house. The purpose of a drop line is to space the newly drilled hole so that it is far enough apart from past years’ drilled holes or wounds so that the operator is utilizing the entire circumference of the tree when tapping from year to year. If an operator is ‘cluster tapping’ (see photo below) or over tapping, then a large area of the tree will not have enough time to heal and will no longer be a producing area of the tree. Not just for sap collection, but also for the transportation of sugars from the leaves to the roots and back to the leaves again because the over tapped area will no longer be available to transport. The length of drop line is of significant importance because if the drop line is not long enough, the operator is unable to utilize the entire circumference of the tree when spacing the hole or holes. The longer the drop line, the better spacing of taps, which leads to increased plant health. Criteria for EPL45 – 28 Inch Drop Line Attach a plan map showing the field locations where a minimum 28-inch drop line is being utilized on each tree being taped for maple syrup production.
