ATCP 50.04(3)(dm)1.1. Standard values specified in Nutrient Application Guidelines for Field, Vegetable and Fruit Crops, UWEX publication A2809 referenced in the NRCS conservation practice standard 590.

ATCP 50.04 NoteNote: The current 2012 version of UWEX pub. A2809 and subsequent editions are available at: https://datcp.wi.gov/Pages/Programs_Services/ATCP50.aspx and are also on file with the department and the legislative fiscal bureau.

ATCP 50.04(3)(e)(e) The plan shall comply with the NRCS conservation practice standard 590 nutrient management (December, 2015) except for sections IV. D., IV. E., and V., and shall also comply with the Wisconsin Conservation Planning Technical Note WI-1 (February, 2016).

ATCP 50.04 NoteNote: The NRCS conservation practice standard 590 (December, 2015) and the companion document Wisconsin Conservation Planning Technical Note WI-1 (February, 2016) are on file with the department and the legislative reference bureau. Copies are available from a county land conservation department, a NRCS field office, the national NRCS website at: http://www.nrcs.usda.gov, the Wisconsin NRCS website at: www.wi.nrcs.usda.gov, or the department website at: https://datcp.wi.gov/Pages/Programs_Services/ATCP50.aspx. Components of a nutrient management plan are summarized on a checklist. An example nutrient management checklist is available at the department’s website at: https://datcp.wi.gov/Pages/Programs_Services/ATCP50.aspx.

ATCP 50.04(3)(f)(f) The plan may not recommend nutrient applications that exceed the amounts required to achieve applicable crop fertility levels recommended by the University of Wisconsin-Extension in the 2012 edition of Nutrient Application Guidelines for Field, Vegetable and Fruit Crops, UWEX publication A2809, or in the latest edition of that publication if preferred by the landowner, unless the nutrient management planner can show that one or more of the following circumstances justifies the recommended application:

ATCP 50.04(3)(f)1.1. A soil or tissue test reveals a specific nutrient deficiency. For supplemental in-season nitrogen applications, a nutrient management planner shall follow steps outlined in NRCS conservation practice standard 590 nutrient management (December 2015).

ATCP 50.04 NoteNote: Environmental conditions can make it challenging to assess nutrient deficiencies. In-field scouting is strongly recommended to verify the nutrient deficiency is not a result of pest or disease pressure, and that an additional nutrient application will resolve the observed deficiency.

ATCP 50.04(3)(f)3.3. Excess nutrients are the result of manure applications made in the last year prior to the implementation of the nutrient management plan.

ATCP 50.04(3)(f)4.4. Other special agronomic conditions documented by the nutrient management planner. A nutrient management planner who wishes to justify higher applications shall include credible information to show that the higher applications will not materially increase environmental damage.

ATCP 50.04 NoteNote: The 2012 edition of the UWEX publication A2809 is on file with the department and the legislative reference bureau. The latest edition of A2809 is available from the UWEX website at: http://learningstore.uwex.edu. Copies are also available from the department website at: https://datcp.wi.gov/Pages/Programs_Services/ATCP50.aspx.

ATCP 50.04(3)(g)(g) The plan shall be consistent with any nutrient management plan required under ch. NR 113, 204, or 214 if the landowner applies septage, municipal sludge, industrial waste, or industrial by-products to the land and in accordance with s. ATCP 65.22 (6) (c). A landowner is not required to have a nutrient management plan under this subsection if the landowner applies primarily septage, municipal sludge, industrial waste, or industrial byproducts according to ch. NR 113, 204, or 214.

ATCP 50.04(3)(gm)(gm) A landowner or nutrient management planner qualified under s. ATCP 50.48 (2) shall annually review a nutrient management plan to determine whether the plan accurately reflects the planned cropping, tolerable soil loss, nutrient application rates, and application methods. The plan shall be updated, by a nutrient management planner qualified under s. ATCP 50.48, when necessary to reflect changes in those planned activities.

ATCP 50.04(3)(i)(i) A landowner is rebuttably presumed to comply with this section if the landowner complies with a nutrient management plan that is prepared or approved by a nutrient management planner who is qualified under s. ATCP 50.48.

ATCP 50.04(4)(a)(a) A landowner shall manage cropland to achieve compliance with the DNR performance standard for tillage setback under s. NR 151.03.

ATCP 50.04(4)(b)(b) A landowner is not required to establish a tillage setback distance greater than 5 feet unless all of the following conditions are met:

ATCP 50.04(4)(b)1.1. The 5-foot setback distance is increased by the smallest increment necessary to achieve the purposes of s. NR 151.03, but in no case greater than a total setback distance of 20 feet.

ATCP 50.04(4)(b)2.2. In determining whether to increase the setback distance, county or other conservation professionals shall do all of the following:

ATCP 50.04(4)(b)2.c.c. Follow a consistent approach in making determinations for increased setback distances by consulting with NRCS or department engineering specialists.

ATCP 50.04(4)(b)2.d.d. Provide the landowner with a written statement documenting the findings and conclusions in support of the increased setback distance.

ATCP 50.04(4)(c)(c) Determinations regarding compliance with this standard may be appealed as authorized under s. 227.42, Stats., or other provisions of law.

ATCP 50.04(5)(a)(a) A landowner shall manage cropland or pasture, or both, to achieve compliance with DNR performance standard for Silurian Bedrock under s. NR 151.075.
