The presence of salts and high water tables in North Dakota soils due to an extended climactic wet cycle recently has stimulated interest in the installation of tile drainage systems. The tile controls the water table and encourages the leaching and removal of salts from the soil above the tile lines. This improves soil productivity, culminating in improved crop yields

This publication defines sodicity and explains the effects it can have on crop production. There is information on the remediation of sodic soils, brine spills, and the importance of calcium amendment mixing.

Saline soils contain salts in great enough abundance that crop yields suffer and sometimes makes successful crop production impossible. This publication talks about testing your soil, salinity management, mapping, crop selection and tile drainage.

Drainage pump stations are an expensive addition to a subsurface drainage project. This publication provides guidance on the design and location of drainage lift stations. This topic an be difficult to teach in typical Extension presentations, this publication provides more details.
