The Action Programme for Nitrate Vulnerable Zones (Scotland) Regulations 2008 No. 298

PART A Farmyard manure (FYM) – Percentage of nitrogen available to next crop following FYM applications (all crops and all soil types).

Table 4

Percentage of Nitrogen available to next crop

FYM type	Manure Reference Number	Total N (kg/t)	Dry Matter %	% N available to following crop
Cattle FYM	1	6	25	10
Separated solids from cattle slurry	2	4	20	10
Pig FYM	3	7	25	10
Separated solids from pig slurry	4	5	20	10
Sheep FYM	5	7	25	10
Duck FYM	6	6.5	25	10
Horse FYM	7	7	30	10

PART B Poultry manure – Percentage of nitrogen available to next crop following Poultry Manure applications (use the value in brackets for grassland and winter oilseed rape cropping).

*These values assume incorporation by ploughing. Cultivation using discs or tines is likely to be less effective in minimising ammonia losses and intermediate values of nitrogen availability should be used.					Autumn		Winter		Spring	Summer use on Grassland
					August–October		November–January		February–April

PART C Cattle, Dirty Water and Pig Slurry – Percentage of nitrogen available to next crop following Cattle Slurry, Dirty Water and Pig Slurry applications (use the value in brackets for grassland and winter oilseed rape cropping).
