Organic manures and mineral fertilizersic manures are bulky, expensive to transport and contain small amounts of nutrients per unit volume. In addition, the amount and rate of release of nutrients from organic manures is often difficult to predict with accuracy, especially for nitrogen. Some of the benefits and concerns about the use of organic manures are discussed in this paper.
