Pig manure makes good compost as the pig muck is mixed with straw.
Pig manure has a very high nutrient content and is rich in potash and phosphorus.
Not only does pig manure enrich the soil which helps plants to grow but it also helps improve the soil structure as the straw (plant material content) in the manure helps the soil to hold water.
Pig manure can be applied to root crops especially leeks and potatoes.
It is important to remember not to apply fresh manure to plants and crops as the manure will scorch the plants. Let the manure mature or apply the manure and work into the soil four weeks prior to planting.
