Recent technological advances in the dairy industry have enabled Canadian farms with liquid manure systems to use mechanical solid-liquid separation paired with composting of the separated solids for on-farm production of low-cost bedding material. However, because several approaches are available, it is difficult for farmers to select the appropriate one …
And for as many different types of soils as there are, there are even more fertilizers available to amend them. Two of the most common fertilizers gardeners utilize are manure and compost. But when you compare manure vs. compost, what's the difference between the two? Manure is animal dung, usually from horses, cows, and chickens.
