Section 327IAC19-14-3. Manure application rates

   (a) The owner/operator of a CFO shall have the results of a soil test prior to any land application events, as well as a manure test. Soil and manure tests shall be conducted in accordance with the manure management plan that is submitted to the commissioner to meet the requirement in 327 IAC 19-7-1(c)(5).

  (b) The application rate of nitrogen (N) must not exceed the N requirements based on the recommendations in:

(1) Purdue University Cooperative Extension Service publication ID-101: Animal Manure as a Plant Nutrient Resource, February 2001, available from the Cooperative Extension Service, Purdue University, West Lafayette, Indiana 47907; or

(2) Tri-State Fertilizer Recommendations for Corn, Soybeans, Wheat and Alfalfa, Extension Bulletin E-2567 (New), July 1995, available from the Cooperative Extension Service, Purdue University, West Lafayette, Indiana 47907;

for current or planned crops of the upcoming growing season as documented in the operating record. Minimum N loss estimates must be used unless otherwise justified. This justification must be kept in the operating record.

  (c) For the first manure application only, nutrient content of manure from facilities constructed after the effective date of this article shall be based on either:

(1) manure test values as described in 327 IAC 19-7-5(d); or

(2) values in the NRCS Agricultural Waste Management Field Handbook (AWMFH) Chapter 4, March 2008, available from the Natural Resources Conservation Service, West National Technology Support Center, 1201 NE Lloyd Boulevard, Suite 1000, Portland, OR 97232 or online at http://policy.nrcs.usda.gov/OpenNonWebContent.aspx?content=17768.wba and applied at fifty percent (50%) of the rate listed in subsection (b).

For all subsequent manure application events, nutrient content values must be based on manure test values.

  (d) As of the effective date of this article, the following must comply with the phosphorus application rates in Table 1:

(1) Large CAFOs, as defined in 40 CFR 122.23(b) that were approved for initial construction after February 13, 2003.

(2) CAFOs with a NPDES permit.

(3) CFOs approved for initial construction after the effective date of this article.

  (e) Beginning with the effective date of this article, CFOs and CAFOs not listed in subsection (d) must comply with the phosphorus application rates in Table 2:

201-250	0.9 × P crop removal	0.75 × P crop removal	0.75 × P crop removal	0
251-275	0.9 × P crop removal	0.75 × P crop removal	0.5 × P crop removal	0
276-300	0.9 × P crop removal	0.75 × P crop removal	0.25 × P crop removal	0
301-350	0.7 × P crop removal	0.5 × P crop removal	0	0
351-400	0.7 × P crop removal	0.25 × P crop removal	0	0
401+	0	0	0	0
1 Multiple years of phosphorus may be applied as long as the net average of phosphorus does not exceed the amounts indicated in Table 2.

  (f) The following land application information must be added to the operating record as needed in accordance with required time frames established in this article and IC 13-18-10 and must be maintained and updated in the operating record:

(1) Expected crop yields.

(2) The date or dates manure, litter, or process wastewater is applied to each field.

(3) Precipitation events at the time of application and for twenty-four (24) hours prior to and following application.

(4) Test methods used to sample and analyze manure, litter, process wastewater, and soil.

(5) Results from manure, litter, process wastewater, and soil sampling.

(6) An explanation of the basis for determining manure, litter, and process wastewater application rates.

(7) Calculations showing the manure nitrogen and phosphorus to be applied to each field.

(8) Total amount of nitrogen and phosphorus actually applied to each field, including documentation of calculations for the total amount applied.

(9) The method used to apply the manure, litter, or process wastewater.

(10) The date or dates of manure, litter, and process wastewater application equipment inspection.

(11) USDA soil survey maps of currently available land application sites.

(12) The type of manure applied.

(13) A written conservation plan with an explanation of conservation practices used must be completed and implemented prior to land application on highly erodible land, if required in section 4(j) of this rule. CAFOs with a NPDES permit must have a nutrient management plan prior to land application on highly erodible land.
