Description
This Standard is intended as a guide to engineers and technicians for the design, layout, construction andmaintenance of terrace systems on cropland. Terraces are earth embankments and channels constructedacross the crop field slope at suitable spacing and with acceptable grades to reduce soil erosion and trapsediment, and/or to retain moisture for crop use.This Standard applies where sheet and rill or gully erosion is aproblem, or there is a need to manage runoff leaving a site. The soils and site conditions must be suitable tobuild an earth embankment. The site must provide an adequate outlet.
Terraces alone may not provide adequate control of erosion and runoff on sloping lands. Used incombination with water and sediment control basins, diversions, contouring, conservation cropping systems,conservation tillage, crop residue management, and/or permanent vegetation, they can be part of a resourcemanagement system to protect the soil and water resource base.2
