SCHEDULE 2 Calculating nitrogen in manure

PART 1 Standard table

Total amount of nitrogen in manure

Manure other than slurry		Total Nitrogen in each tonne (kg)
Manure other than slurry from—
	cattle:	6
	pigs:	7
	sheep:	6
	ducks:	6.5
Manure from laying hens:		16
Manure from turkeys or broiler chickens:		30

Slurry		Total Nitrogen in each cubic metre (kg)
Dairy cattle:		3
Beef cattle:		2
Pigs:		4.0
Separated cattle slurry (liquid fraction)—
	strainer box:	1.5
	weeping wall:	2.0
	mechanical separator:	3.0
Separated cattle slurry (solid fraction):		4
Separated pig slurry (liquid fraction):		3.6
Separated pig slurry (solid fraction):		5

PART 2 Sampling and analysis

Slurry

1.—(1) At least five samples, each of 2 litres, must be taken.

(2) The sample must be taken from a slurry vessel, and—

(a) if reasonably practicable, the slurry must be thoroughly mixed before the samples are taken, and

(b) each sample must be taken from a different location.

(3) But if a tanker used for spreading is fitted with a suitable valve, the samples may be taken while spreading, and each sample must be taken at intervals during the spreading.

(4) The samples must be poured into a larger container, stirred thoroughly and a 2 litre sample must be taken from that container and poured into a smaller clean container.

(5) That sample must then be sent for analysis.

Solid manures

2.—(1) The samples must be taken from a manure heap.

(2) At least ten sub-samples of 1kg each must be taken. each from a different location in a heap.

(3) Each sub-sample must be taken at least 0.5 metres from the surface of the heap.

(4) If samples are being collected to calculate compliance with the whole farm limit for pigs and poultry, four samples for analysis must be taken in a calendar year (one taken in each quarter) from manure heaps not more than 12 months old.

(5) The sub-samples must be placed on a clean, dry tray or sheet.

(6) Any lumps must be broken up and the sub-samples must be thoroughly mixed together.

(7) A representative sample of at least 2kg must then be sent for analysis.

Regulation 27

SCHEDULE 3 Permitted crops for the closed period

(a) Nitrogen must not be spread on these crops after 31st October.
(b) An additional 50 kg of nitrogen per hectare may be spread every four weeks during the closed period up to the date of harvest.
(c) A maximum of 40 kg of nitrogen per hectare may be spread at any one time.
Crop		Maximum nitrogen rate (kg/hectare)

Asparagus	50
Brassica(b)	100
Grass(a) (c)	80
