 note = {The method of land disposal was subjected to a field test. The soil permeating water was sampled by-the soil-permeating -water sampling devices set at a depth of 120 cm and analyzed together with original wastewater. The average removal of nutrients in soil permeating water based on the original wastewater was registered as 91.0-99.6% biological oxygen demand(BOD)，2 6.6-64.3% total nitrogen (T-N)， and 83.9-98.0% total phosphorus(T -P). Soil samples were collected from the wastewater permeating area at each 50 cm mesh point in the range of 50 to 280 cm in depth and of 600 cm in width and analyzed together with soil samples collected from the control plot. The concentration of T-P in soil samples increased significantly in the region directly below trench in the range of 60 to 100 cm in depth as compared with that in the control plot. However， no remarkable differences in the concentration of T -N and total carbon (T -C) could be observed even in the soiI samples collected from directly below trench., Article, 信州大学環境科学論集7:38-46(1985)},
