Production of Educational Video Tape "Message from Soils"

日本遇到的主要土壤（泥炭土、重粘土、火山灰土、棕色森林土、水稻土、红黄土和未熟化沙土）的形态、景观和土地利用都被记录在录像带中。从代表性地点采集土壤样品，并进行物理化学和矿物学特征分析。土壤图制备和巨石制备方法被记录在录像带中。还记录了世界上观察到的主要全球环境问题（中国的荒漠化、马来西亚的泥炭地和热带雨林的破坏以及日本和欧洲国家的酸雨）。上述主题被编成一本教育小册子。还准备了母带，进一步编制了《土壤学基础课》、《土壤学高级课》、《土壤调查手册》、《世界环境问题》等大学和高中教育视听工具。

Major soils encountered in Japan (peat soils, heavy clay soils, volcanic ash soils, brown forest soils, paddy soils, red and yellow soils and unmatured sandy soils) were recorded into video tapes with their morphology as well as landscape and land use. Soile samples were collected from representative sites and analyzed for physico-chemical and mineralogical characterzation.The methods of soil map preparation and monoliths preparation were recorded into video tapes. Major global environmental problems observed in the world (desertification in China, destruction of peat land and tropical rain forest in Malaysia and acid rain in Japan and European countries) were also recorded.The above mentioned topics were compiled into a booklet for educational use. Master tapes were also prepared for further compilation of audio-visual tools for the education in universities and high schools, such as "fundamental course of soil science, " "advanced course of soil science, " "soil survey manual, " "environmental problems in the world."
