Table 4

Regulations 10 and 12 - Nitrogen application standards for grassland crops

1 This table does not imply any departure from regulation 9(1) which prohibits the application to the agricultural area on a holding of livestock manure in amounts which exceed 170 kg N/ha/year, including that deposited by the animals themselves, or, in the case of grassland holdings granted a derogation in accordance with regulation 12, 250 kg of N/ha/year, including that deposited by the animals themselves.
2 The dairy cattle figures (dairy cows and heifer replacements) apply where it can be demonstrated that more than 50 % of the livestock manure applied to the agricultural area, both by land application and by the animals themselves, arises from dairy cattle. In all other cases the figures for other livestock will apply.
	Dairy cattle2	Other livestock2
Balance of crop nitrogen requirement (kg N/ha/year) (e.g. from chemical fertiliser or organic nitrogen supply other than livestock manure)1	272	222

Table 5

Regulations 11 and 12 - Maximum permitted nitrogen application and standard yields for cereal crops

1 For all crops in the table, an additional 20 kg N /ha is permitted for every tonne that the expected yield exceeds the standard yield. Evidence of this must be demonstrated by overall farm crop yield in any of the previous three years.
Crop type	Maximum permitted nitrogen (kg N/ha)1	Standard yield (t/ha)

Regulation 12(7) - Criteria as to calculation of phosphorus balance N.I.

1.—(1) Phosphorus balance is the difference between phosphorus inputs to the holding less the total of phosphorus outputs leaving the holding. It is calculated per unit area of agricultural land on the holding for each calendar year.

(2) Phosphorus inputs include, when imported on to the holding—

(a) the total amount of phosphorus in chemical fertiliser;

(b) the total amount of phosphorus in feedstuffs (calculated using values from Table 7); and

(c) the total amount of phosphorus in organic manure (calculated using values from Table 2).

(3) Phosphorus outputs include, when exported from the holding—

(a) the total amount of phosphorus in produce, for example, meat, milk and crops (calculated using values from Table 7); and

(b) the total amount of phosphorus in organic manure (calculated using values from Table 2).

(4) Inputs of phosphorus to agricultural land in precipitation and losses of phosphorus from the holding to any waterway or water contained in any underground strata are excluded from the balance calculation.
