[Synopsis] 　It examined with Kuriyama-cho eco-soil centre concerning the stink decrease by three kinds of different materials and densities, and the following results were obtained. 1.The effect on the density of ammonia by the bacterium was compared with the control plot and the density of ammonia changed low. The density of ammonia changed a little higher than other examination districts with the time passage. 2.The decrease in the density of ammonia was seen as for the effect on the density of ammonia with the horseradish extraction thing immediately after processing, and a deodorant effect continued for a long time. Moreover, a deodorant effect of the horseradish extraction thing is a point that the quality of the smell changes momentarily, and the stink disappears due to the stink. 3.The effects on the concentration of ammonia with humus decreasing the density of ammonia became clear. 4.It was suggested the concentration of ammonia to be able to change low, and to decrease the stench from the result of the examination by either materials compared with the control plot. The effect and the quantity consumed of each material during summer were examined in addition, and the necessity for examining the point of cost-effectiveness was admitted in the future.
