PART 2Sampling and analysis of organic manure
Slurry and other liquid and semi-liquid organic manureI21
1
In relation to slurry and other liquid and semi-liquid organic manure, at least five samples, each of 2 litres, must be taken.
2
Subject to sub-paragraph (3), the five samples must be taken from a 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
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
Whether taken as described in sub-paragraph (2) or (3), the five 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
The 2 litre sample produced in accordance with sub-paragraph (4) must then be sent for analysis.
Solid manuresI32
1
In relation to solid manures, the samples must be taken from a manure heap.
2
At least ten samples of 1 kg 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 2 kg must then be sent for analysis.
