Livestock typeProduction period or age rangeBody weight (kg)Occupancy % of year(1)Annual nitrogen production (kg N)
(1)

For individual farms where occupancy values differ from those given, nitrogen excretion values should be altered accordingly.

Use the suckler cow data for beef and dairy bulls.

(3)

Maiden gilts, assuming all year round accommodation.

(4)

Sows based on 2.3 lactations, covering 23 per cent of year and dry period 77 per cent of year. Combined output 15.9 kg N/sow/year.

(5)

Broilers, output per 6.6 crops/year, 40 day cycle (73 per cent occupancy).

(6)

Broiler breeder replacements, output/24week cycle. Where there is more than one cycle per year adjust the output figures proportionately.

(7)

Replacement pullets, output per 20 week cycle. Where there is more than one cycle per year adjust the output figures proportionately.

(8)

Turkeys, assuming 2.1 or 2.4 crops per year, for male and female birds respectively.

Regulation 8(2) and 10(4) - Nitrogen application standards for grassland crops

Dairy cattle(2)Other livestock(2)
(1)

This table does not imply any departure from regulation 8(1) or 9(3) which prohibit the application to the agricultural area on a holding of livestock manure in amounts which exceed 170kg N/ha/year, including that deposited by the animals themselves, or, in the case of grassland holdings granted a derogation in accordance with regulation 10, 250kg 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.

PART 2Criteria as to calculation of phosphorus balance

1.—(1) Phosphorus balance is the difference between phosphorus inputs to the farm less the total of phosphorus outputs leaving the farm. 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 farm—

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

(b)the total amount of phosphorus in feedstuffs (calculated using values from Table 8); and

(c)the total amount of phosphorus in organic manure (calculated using values from Table 9).

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

(a)the total amount of phosphorus in produce, for example, meat, milk and crops (calculated using values from Table 8); and

(b)the total amount of phosphorus in organic manure (calculated using values from Table 9).

(4) Inputs of phosphorus to agricultural land in precipitation and losses of phosphorus from the farm to surface or groundwaters are excluded from the balance calculation.
