Requirements for application of prescribed materials
 52.5 (1) Subject to sections 52.3 and 52.4, no person shall apply prescribed materials to land, except in accordance with this section, (a) during the restricted period; or (b) at any other time when the soil is snow-covered or frozen. O. Reg. 338/09, s. 43. (2) The following rules govern the application of solid or liquid Category 3 NASM other than sewage biosolids, liquid Category 2 NASM and liquid ASM during the restricted period if the soil is not snow-covered or frozen: 1. Subject to paragraph 2, the application must be done by, i. injection, or ii. spreading and incorporation into the soil within the same day. 2. If at least 30 per cent of the land surface is covered by crop residue, as determined in accordance with the Nutrient Management Protocol, or if the land is covered by a living crop, the application must be done by one of the methods described in paragraph 1 or by surface application. 3. The setback from the top of the bank of surface water must be 20 metres or more. 4. If the maximum sustained slope of the land is greater than 3 per cent, the materials must not be applied within 100 metres from the top of the bank of surface water. O. Reg. 338/09, s. 43; O. Reg. 284/12, s. 7 (2); O. Reg. 848/21, s. 3 (1). (3) The following rules govern the application of solid or liquid Category 3 NASM other than sewage biosolids, liquid Category 2 NASM and liquid ASM at any time when the soil is snow-covered or frozen: 1. The application must be done by, i. injection, or ii. spreading and incorporation into the soil within six hours. 2. The setback from the top of the bank of surface water must be 20 metres or more. 3. If the maximum sustained slope of the land is greater than 3 per cent, the materials must not be applied within 100 metres from the top of the bank of surface water. O. Reg. 338/09, s. 43. (4) The following rules govern the application of solid Category 2 NASM, solid or liquid Category 1 NASM and solid ASM during the restricted period if the soil is not snow-covered or frozen: 1. Subject to paragraph 2, the application must be done by, i. injection, or ii. spreading and incorporation into the soil within the same day. 2. If at least 30 per cent of the land surface is covered by crop residue, as determined in accordance with the Nutrient Management Protocol, or if the land is covered by a living crop, the application must be done by one of the methods described in paragraph 1 or by surface application. 3. If the materials are solid Category 2 NASM, or solid or liquid Category 1 NASM, the setback from the top of the bank of surface water must be 20 metres or more. 4. If the materials are solid ASM, there is no minimum setback from the top of the bank of surface water. 5. If the maximum sustained slope of the land is greater than 6 per cent, the materials must not be applied within 100 metres from the top of the bank of surface water. O. Reg. 338/09, s. 43; O. Reg. 284/12, s. 7 (2); O. Reg. 848/21, s. 3 (2). (5) The following rules govern the application of solid Category 2 NASM, solid or liquid Category 1 NASM and solid ASM at any time when the soil is snow-covered or frozen, if the application is done by injection or by spreading and incorporation into the soil within six hours. 1. If the materials are solid Category 2 NASM, or solid or liquid Category 1 NASM, the setback from the top of the bank of surface water must be 20 metres or more. 2. If the materials are solid ASM, there is no minimum setback from the top of the bank of surface water. 3. If the maximum sustained slope of the land is greater than 6 per cent, the materials must not be applied within 100 metres from the top of the bank of surface water. O. Reg. 338/09, s. 43. (6) The following rules govern the application of solid ASM at any time when the soil is snow-covered or frozen, if the application is done by surface application: 1. The setback from the top of the bank of surface water must be 100 metres or more. 2. The maximum depth of snow in the area of application must not exceed 15 centimetres. 3. The maximum sustained slope of the area of application must be less than 3 per cent. O. Reg. 338/09, s. 43. Application Methods
