비료자원(肥料資源)으로서 유망시(有望視)되는 주정오이(酒精汚泥)의 비효(肥效) 및 시용적량(施用適量)을 구명(究明)하기 위(爲)하여 수도(水稻)에 시용(視用)한 결과(結果)는 다음과 같다. 주정오이(酒精汚泥)의 무기화(無機化)는 퇴비(堆肥)에 비(比)하여 비교적(比較的) 빨랐으며 수도생육량(水稻生育量) 및 식물체중(植物體中) N함량(含量)은 오이시용량(汚泥施用量)이 증가(增加)되었으나 수량(收量)은 1.600kg/10a부터 급격(急激)히 감소(減少)되어 수도(水稻)에서 오이(汚泥)의 적정시용량(適正施用量)은 800kg/10a로 추정(推定)되었다. 따라서 주정오이(酒精汚泥)는 유기질비료자원(有機質肥料資源) 및 토양개량제(土壤改良劑)로 활용(活用)이 가능(可能)할 것으로 판단(判斷)되었다. An activated sludge from alcohol fermentation was applied on rice field to determine the effect of the sludge on rice growth and its optimum application rate. The mineralization of sludge was rather rapid compared to compost and about 60% of the total nitrogen in sludge applied was decomposed. Plant growth and nitrogen content in plant increased as sludge application rate increased but the yield markedly decreased when more than 1,600kg/10a of sludge was applied. The optimum application rate was found to be 800kg/10a. Results from this experiment confirm that the sludge from alcohol fermentation is potentially useful resources for organic fertilizers and soil amendments.
학회순례 - 1968년 창립 1천여 회원 농업발전 공헌 "한국토양비료학회"
신제성,Sin, Je-Seong 한국과학기술단체총연합회 2000 과학과 기술 Vol.33 No.6
한국토양비료학회는 '보리고개'의 악몽이 채 가시지 않았던 1968년에 창립되어 토양개량과 적정시비를 통해 우리나라 농업발전에 크게 기여해 왔다. 농업인, 농업연구지도직, 대학교수 등 1천여명의 회원으로 구성된 이 학회는 매년 두 차례 학술발표회를 열고 있으며 1988년과 1996년에는 국제 심포지엄을 유치하는 등 다양한 학술활동을 펴왔다. 특히 올해부터는 학회지를 영문으로 연 6회 발행하고 있으며 젊은 과학자 중심으로 해외 학술활동에도 적극 참여하고 있다.
수도상자육묘용(水稻箱子育苗用) 상토자재개발(床土資材開發)

This study was conducted to develop the homemade soil media adequate to raising rice seedlings for machine transplanting. A raising experiment of rice seedlings was tested on a newly developed soil medium made mainly from briquette ash compared to ones of infertile red earth and fertile paddy loams. Dry weight of rice seedlings at 36 days after seeding was slighly lower in the plot of briquette ash that in soils, however, it was quite good in the plot of briquette ash mixed with zeolite and diatomaceous earth. pH in soil media was high in briquette ash and also high in soils mixed compost compared with out compost treatment, resulting in higher occurrence of damping off or physiological disorder. Good rice seedlings could be raised in soil media without compost and briquette ash mixed with zeolite diatomaceous earth. 수도육묘용(水稻育苗用) 상토(床土)의 자가제조이용(自家製造利用)을 목적(目的)으로 상토개발(床土開發)을 연탄재를 활용(活用)하여 수행(遂行)하였으며 일반(一般) 논양토(壤土) 및 산양토(壤土)를 대조(對照)로 하여 육묘시험(育苗試驗)을 한 결과(結果) 연탄재 단독(單獨)에서는 건물중(乾物重)이 다소 떨어졌으나 연탄재+제오라이트, 연탄재+규조토(硅藻土)에서는 대조(對照)와 대등(對等)하였다. 한편 상토(床土)의 pH는 연탄재단독(單獨)과 토양(土壤)에 퇴비(堆肥)를 혼합(混合)한 상토(床土)에서 높아 립고병(立枯病)이 발병(發病)되었다. 토양(土壤)에 퇴비(堆肥)를 혼합(混合)하지 않고도 양묘(良苗)의 육성(育成)이 가능(可能)하였으며 특(特)히 연탄재를 이용(利用)하여 제조(製造)한 상토(床土)에서도 양묘(良苗)의 육성(育成)이 가능(可能)하였다.

An increased population and rapidly expanding industrial development have led to enormous amounts of various domestic and industrial wastes. The proper disposal of ever-increasing wastes is a growing global problem. Land treatment is one of the rational approaches that are environmentally safe and economically practical. It has long been practised in many sites. Recycling of industrial wastes on agricultural land can provide better possible means for maintaining environmental quality and utilizing waste-resources. Even though industrial wastes are beneficial as soil amendment and fertilizer, they have some limitation on land application because of wide variability as well as physicochemical problem in their composition. A direct application of solid and liquid wastes on land is being practised in Korea and some experimental results are presented. The direct application of fermentation waste on rice resulted in a 6 percent yield increase. Another organic residue from glutamic acid fermentation is widely used not only as a direct application as a liquid fertilizer but also for a raw material of organic compound fertilizer. These wastes are much promising as sources of plant nutrients, since they have large amounts of nutrients, especially nitrogen with few toxic metals. On the other hand, fertilizers developed from inorganic industrial wastes include calcium silicate, calcium sulfate and ammonium sulfate. The calcium silicate fertilizer simply produced from slag, by-product of iron and steel manufacturing plant is one of the most successful example of the conversion of wastes to fertilizer and slag production capacity totals to over three million MT/year. About 200,000 MT of calcium silicate fertilizer is currently applied in the paddy rice every year. Calcium sulfate, a waste from the wet phosphoric acid process is to some extent used as a filler of compound fertilizers but quite large quantites are directly applied for the reclamation of tidal flat.
