In this report, animal manure management is defined as a decision- making process hyphen aiming to combine profitable agricultural production with minimum nutrient losses from manure, for the present and in the future. Good manure management will minimize the negative and stimulate the positive effects on the environment. Emissions to the air of nutrients, organic matter1 and odour, have adverse effects on the environment. The contribution of manure to plant nutrition and build up of soil organi c matter is considered a positive effect.
