As a partially decomposed organic matter, compost can have a number of characteristics. Compost can vary due to the use of raw materials, degree of decomposition, moisture content, nutrient content, solids content, acidity / alkalinity and contaminants (organic and non-environmental materials or heavy metals). Not only mere quality, such as carbon / nitrogen ratio, odour and particle size, indicate some of the best characteristics or efficiencies of process composting. Large particle sizes indicate incomplete decomposition. Bad smell is a sign of too moist or too pile of compost. The finished compost is dark in colour, chopped and has a earthy odour. Original source materials should not be recognizable. Inert materials such as glass or plastic should ideally not be present for more than 1 compost volume process. The aim of this paper is to determine and use quality 3 types of compost of different origin for use in organic agriculture.
