The puprpose of this study is to compare the subjectivity judgement of the condition of compost made from plant waste with the result of the analysis of ingredients (carbon, nitorogen, C/N, moisture content, humus, EC, pH (H2O), microbia activity). We showed 5 kinds of compost taken from the different factories to 76 subjects who work as a landscape architecture and asked them those condition in seven grades. Our results show that the compost that contain a lot of nitorogen or humus and the lower C/N compost are considered available. On the other hand there is compost that is considered unavailable, though it has the available result of the analysis of ingredients .And career have little effect on the judgement of compost condition.
