Drain Spacing Tool


February 28, 2022 - <ghane@msu.edu>,

The Drain Spacing Tool estimates the optimum spacing of 4-inch lateral drain pipes that maximizes economic return on investment. For soils that would benefit from subsurface (tile) drainage, use this tool to estimate the optimum drain spacing for any rotation of corn and soybean. The tool has a geographical user interface that allows navigating to a specific field in the Midwest USA. Once at the specific field, enter a few simple inputs. Then, the tool uses site-specific soil and weather data to estimate the optimum drain spacing. An advanced input setting is also available for entering custom soil and economic inputs for a tailored analysis.
