Work out your farm's total nitrogen produced against your maximum permitted organic N, using DAFM category excretion rates. Follows the standard three-part structure: conditions, farmed area, then livestock on the farm.
1Conditions
2Farmed area
Answer the derogation question in Step 1 to see the area fields that apply to your farm.
3Nitrogen produced on the farm
Dairy
Roughly increasing milk-yield bands, lowest to highest — confirm the current published yield thresholds for each band with DAFM if you're unsure which applies to your herd.
Other bovine
Non-bovine grazing livestock
Non-grazing livestock
This touches Nitrates Regulations / scheme rules, which change. This is a planning aid, not a substitute for an official Nutrient Management Plan or DAFM confirmation — check current rules before acting on it.
