Two new University of Minnesota Extension Service publications address
planning, design and performance of tile drainage. These publications
are the first of an upcoming series on agricultural drainage.
Agricultural Drainage: Planning an Agricultural Subsurface Drainage
System (BU-07685-GO)
Topics include economics, system capacity and drainage coefficient,
topography and system layout, drain depth and spacing, drain sizing,
use of drain envelopes, environmental impacts, surface inlets and installation
quality. There are also general rules of thumb, recommendations, design
tables and references to resources and agencies for more detailed information.
This publication was designed for farmers, engineers, public agencies,
crop consultants, Extension educators, and water quality professionals
across the Midwest region. The authors of this publication are University
of Minnesota Extension Engineers Jerry Wright and Gary Sands.
Agricultural Drainage: Soil Water Concepts (BU-07644-GO)
This is an 8-page, heavily illustrated publication presenting concepts
that are fundamental to understanding how subsurface drainage affects
soil water and the water balance. It explains–with practical examples–the
components of the water balance in the crop/soil system and their relationship
to drainage. It also has answers to common questions about drainage,
soil water, and hydrology to help guide policy makers as they address
broad issues related to agricultural drainage. This publication was
designed for agriculturists, engineers, soil scientists, local and state
policymakers, Extension educators, and water quality professionals.
The author of this publication is Gary Sands.
