This standard applies to the use of technologies and methods for the resource utilization of cattle manure fermentation substrates in dairy farms in Liaoning Province; Main technical content: The limit values of heavy metals in cattle manure fermentation substrates shall comply with the requirements of Table 2. **Table 2** **Unit**: milligrams per kilogram **Item**: **Limit value** **Total arsenic (As)** (based on dry basis) ≤ 15 **Total mercury (Hg)** (based on dry basis) ≤ 2 **Total lead (Pb)** (based on dry basis) ≤ 50 **Total cadmium (Cd)** (based on dry basis) ≤ 3 **Total chromium (Cr)** (based on dry basis) ≤ 150 **Application methods of cattle manure fermentation substrates as base fertilizer**: 1. **Broadcast application**: Evenly spread on the ground before plowing and incorporate into the soil during plowing to ensure compatibility between fertilizer and soil. This method is suitable for open fields, protected areas, and orchards. 2. **Strip-till application**: Combined with plowing, apply the fertilizer along the rows of crops. This method is suitable for open fields, vegetables, and medicinal plants. 3. **Hole application**: Apply fertilizer in the planting holes of crops. This method is suitable for open fields, vegetables, and medicinal plants. 4. **Ring application (rotary application)**: Apply fertilizer in the grooves around the main stem of crops and cover with soil. This method is suitable for fertilizing perennial fruit trees. **Precautions**: - Do not apply in water source protection areas. - Avoid applying during the rainy season in agricultural areas. - After applying to bare farmland, cover with soil within 24 hours.
