NR 120.14(2)(c) (c) Standards. Standards from the NRCS field office technical guide are as follows:

NR 120.14(2)(c)1. 1. 330 — contour farming; May, 1986.

NR 120.14(2)(c)2. 2. 500 — obstruction removal; January, 1983.

NR 120.14(2)(c)3. 3. 606 — subsurface drain; September, 1989.

NR 120.14(3) (3) Contour and field stripcropping.

NR 120.14(3)(a) (a) Description. Contour and field stripcropping is growing crops in a systematic arrangement of strips or bands, usually on the contour, in alternated strips of close growing crops, such as grasses or legumes, and tilled row crops. This practice shall be implemented using one or more of the standards in par. (c).

NR 120.14(3)(b) (b) Conditions. Cost-sharing may be provided for the establishment of the stripcropping system including field stripcropping.

NR 120.14(4) (4) Field diversions.

NR 120.14(4)(a) (a) Description. Field diversions are structures installed to divert excess water to areas where it can be used, transported or discharged without causing excessive erosion or contacting materials with water pollution potential. Usually the system is a channel with a supporting ridge on the lower side constructed across the slope at a suitable grade with a self-discharging and non-erosive gradient. This practice shall be implemented using one or more of the standards in par. (c).

NR 120.14(4)(b) (b) Conditions.
