NR 120.14(2)(a)(a) Description. Contour farming is farming on sloped land so all cultural operations from seedbed preparation to harvest are done on the contour. This practice shall be implemented using one or more of the standards in par. (c). NR 120.14(2)(b)(b) Conditions. Cost-sharing may be provided for the establishment of a contour farming system and, if necessary, subsurface drains and the removal of obstructions. NR 120.14(2)(c)(c) Standards. Standards from the NRCS field office technical guide are as follows: 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(3)(c)(c) Standards. Standards from the NRCS field office technical guide are as follows: 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)1.a.a. Diversions and subsurface drains necessary for proper functioning of the diversion. Cost-sharing for subsurface drains is limited to areas on sloping land where the internal water seeps to the surface and causes the land or cover to lose its stability. NR 120.14(4)(b)1.b.b. Installations of structures such as pipe, underground outlets or other outlets, if needed, for proper functioning of the dike, for more even flow or to protect outlets from erosion. NR 120.14(4)(b)3.3. Cost-sharing may not be authorized for ditches or dikes designed to impound water for later use, or which will be a part of a regular irrigation system. NR 120.14(4)(c)(c) Standards. Standards are the following from the NRCS field office technical guide:
