| The nutrient content of animal manures varies with the dilution. The
recommendations in the Code of Good Practice relate to well stored animal manure. |
| Covered slatted stored cattle slurry would have 7% to 8% dry matter. |
| Note - 11m3 per hectare = 1,000 gallons per acre. |
| 4.5 tonnes (4,572 Kgs) of dungstead manure are the equivalent weight of
1,000 gallons of slurry. |
| Guide values for the nutrient content of a range of farm slurries and
manures is given below. |

*Note all the nitrogen is not available for plant growth. Its availability can vary from 0
to 50% depending on type of manure, time and method of application. Only 25% of the
nitrogen is available for Spring applications. Assume no nitrogen contribution from slurry
or manure applied at other times of year |
