NPK Values of Common types of Animal Farmyard Manure

Don’t forget that Manure also supplies valuable humus to the soil that Chemical Fertilisers do not.

These figures are for Farmyard Manure that is over 3 months old, fresh manure would have around double the amount of readily available Nitrogen, i.e. 1.2 for Cows, 1.8 for Pigs and 1.4 for Sheep.   Obviously the animals diet will have some effect of the nutrient content of Manure.   


The difference in availability of Nitrogen is mainly due to the amounts of liquid ammonia in fresh manure, this comes from the higher liquid content in fresh manure from the urine and faeces before they have dried. Other factors that effect these figure are how quickly the manure is incorporated by digging into the soil and the rainfall between spreading and planting.   Nitrogen is easily washed out of the top soil.
