Outlines of the result in the 2001 fiscal year are as follows. 1)Sun and wind force hybrid electric power generation were average 15% of the electric power necessary for the operation of the barn system, and the proportion of the wind fore? Was about 30%. 2)Though ammonia gas concentration in the cattle barn was before the sealing processing around Ippm, it rose after the sealing by the place at 9ppm. 3)There were odorous components such as buiyric acid in the air internal and external cattle barn. 4)Unsteady air infiltration model test using Andosol and sand was started in order to examine the basic problem of the gas absorption with the passage of the air in the soil deodorization space. 5)In the grassland which scattered the compost produced by the composting equipment, the field test which examines grass growth and change of characteristics of the soil was started. 6)Though the grass yield was hard to recognize the significance of 3 wards of (the compost plot), (the chemical fertilizer plot)and(the compost + chemical fertilizer plot). 7)Within the soil animal of the compost spraying grassland, self-support nematode of the compost plot was remarkably increased. 8)Results of monitoring the soil moisture of FM Tsukui and circumference for 2 years are as follows. (1)The concentration of nitrate ion and sulfate ion increased with the depth, and pH decreased. (2)In the mechanism of the soil acidification, it was guessed that fertilizer and ammonium ion of the atmospheric precipitation derivation changed to nitric acid by nutrifying bacteria. (3)It was guessed that the fertilization contributed for increment in concentration of sulfate ion in the soil.

二零零一年财政年度的结果概要如下：1)太阳能和风力混合发电平均占粮仓系统运行所需电力的15%，风力发电所占比例为？大约是30%。(2)牛棚内氨气浓度在密封处理前约为Ippm，但经过场所密封后，氨气浓度上升至9ppm。3)牛棚内外空气中存在乙酸等恶臭成分。4)为研究土壤除臭空间中气体随空气通过而吸收的基本问题，开展了安多索和砂土的非定常空气入渗模型试验。5)在抛撒堆肥设备产生的堆肥的草地上，进行了禾草生长和土壤特性变化的田间试验。6)虽然草产量很难识别（堆肥小区）、（化肥小区）和（堆肥+化肥小区）3个小区的意义。7)喷施堆肥草地土壤动物中，堆肥小区自养线虫数量显著增加。8)对Tsukui FM及周边2年土壤水分监测结果如下：(1)硝酸盐离子和硫酸盐离子浓度随深度增加而增加，pH值降低。(2)在土壤酸化机理上，推测大气降水衍生的肥料和铵离子通过营养菌转化为硝酸。(3)推测施肥对土壤中硫酸盐离子浓度的增加有贡献。
