(1)For individual farms where occupancy values differ from those given, nitrogen excretion values should be altered accordingly.
(2)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 19.5 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.

This table does not imply any departure from regulation 9(2) or 10(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. Where the 250kg N/ha/year derogation under regulation 10A is granted to a controller the nitrogen application standards for 2010 shall apply to the derogated holding.
* 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.

Phosphorus (P) content of Organic Manures
Agricultural Product
Dry Matter %
Phosphorus content (kg P/m3)
(1)Figures in bold are most common values.
(2)For calculation purposes assume 1m3 of slurry weighs 1 tonne.
The phosphorus balance will be 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 and is based upon the following:
Inputs include:
P in chemical fertiliser (quantity and P content)
P in feedstuffs (quantity and P content)
P in any organic manure imported onto farm (quantity and P content – use standard values for P content)
less
Outputs include:
P in produce – for example meat, milk and crops (use standard values for P content of each product)
P exported in organic manures (quantity and P content)
The balance is inputs less outputs divided by the agricultural area for each calendar year.
Note: 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.
