(1) Each person who is required to have a nutrient management plan for an agricultural operation, in the course of which manure or anaerobic digestion output that falls within the definition of agricultural source material is applied to land, that is the first such plan for the operation, shall, as part of preparing the plan, (a) collect at least one sample from the soil of the land or, if the plan deals with land in parts under subsection 24 (3), from each part of the land and have the sample analyzed in accordance with subsection (4) to determine the concentration of each of the following parameters: plant available phosphorus, plant available potassium; or (b) for the purpose of subsection 92 (1), use the following concentrations to calculate the maximum application rate to land: (i) 101 milligrams per litre of plant available phosphorus in the soil of the land. (ii) 251 milligrams per litre of plant available potassium in the soil of the land. O. Reg. 511/05, s. 48; O. Reg. 394/07, s. 15 (1); O. Reg. 338/09, s. 68 (1-3). (2) Each person who is required to have a nutrient management plan for an agricultural operation, in the course of which manure or anaerobic digestion output that falls within the definition of agricultural source material is applied to land, that is not the first such plan for the operation, shall, as part of preparing the plan, collect at least one sample from the soil of the land or, if the plan deals with land in parts under subsection 24 (3), from each part of the land and have the sample analyzed in accordance with subsection (4) to determine the concentration of each of the following parameters: plant available phosphorus and plant available potassium. O. Reg. 511/05, s. 48; O. Reg. 394/07, s. 15 (2); O. Reg. 338/09, s. 68 (4). (3) Each person who is required to have a nutrient management plan for an agricultural operation, in the course of which manure or anaerobic digestion output that falls within the definition of agricultural source material is applied to land, shall, as part of preparing the plan, (a) collect at least one sample of each type of the manure or anaerobic digestion output applied to the land and have the sample analyzed in accordance with subsection (4) to determine the concentration of each of the following parameters: ammonia and ammonium nitrogen, total Kjeldahl nitrogen, total phosphorus, total potassium and total solids; or (b) obtain the default data from the Nutrient Management Protocol in relation to each parameter listed in clause (a). O. Reg. 511/05, s. 48; O. Reg. 394/07, s. 15 (3, 4); O. Reg. 338/09, s. 68 (5); O. Reg. 284/12, s. 7 (2). (4) The analysis mentioned in subsection (1) or (2) shall be performed by a laboratory that is accredited by the Ministry of Agriculture, Food and Rural Affairs for that purpose. O. Reg. 394/07, s. 15 (5). (5) The analysis mentioned in subsection (3) shall be performed by, (a) a laboratory that is accredited by the Ministry of Agriculture, Food and Rural Affairs for that purpose; or (b) a laboratory that is accredited in accordance with the International Standard ISO/IEC 17025 — General Requirement for the Competence of Testing and Calibration Laboratories, dated December 15, 1999, as amended from time to time. O. Reg. 394/07, s. 15 (5).
