Seedling potting mix is made using sand,compost, coconut fiber, bedding wood chips, bone meal, garden soil to add some microbes), and the ingredients are mixed thoroughly using the Honda FG110 small high speed rototiller. The amount of any ingredients is subjective and based on experience and appearance. Total quantity made was 250 liters, which should meet my requirements. This mixture will be used for starting seeds indoors beginning about March 2011.
