using the table in Part 1 of Schedule 3, or

b

sampling and analysis in accordance with Part 2 of Schedule 3.

40 %

Pig slurry

50 %

Poultry manure

30 %

Other livestock manure

10 %

3

In relation to all other organic manure, the occupier must establish the total amount of nitrogen available for crop uptake in the growing season in which it is spread, for the purposes of regulation 8—

a

by reference to technical analyses provided by the supplier,

b

to the extent that such information is unavailable, by reference to the values given in the Nutrient Management Guide (RB209)4, or
