'Pasturing' Nagoya kouchin, the kind of chicken that is the specially produced in Aichi Prefecture, in land cultivated with the Japanese Pear 'Kousui' was implemented to reduce labor costs in soil management. The influence that it exerts on the growth of Kousui, on the component in the leaves of Kousui and on soil nutrition, grass and sod cultivation was investigated. Releasing of the chickens for 50-70 days from mid April with the density of 1 chicken per 3.3 square meter exerted little influence on the growth, amount of harvested pear and fruit quality, however, it was able to cut 50% of the fertilizer requirement by way of the the chicken manure. The availability of greens provided feed for the chickens which trims the ground. By 'pasturing' the chickens, increases in soil nutrient content were observed with NO3-N + NO2-N and K2O. The earlier the pasturing time was done, the faster the increase in the pear leaf component taken, in as N, P,K. Labor-saving on weeding work was completely attained by pasturing chicken in Kousui plantation
