At the previous papers, we showed that K2O-CaO-P2O5 glasses had a solubility in air so that they could be used for glass fertilizer. In this work, we fabricated the Eco-glass fertilizer containing trace elements such as B, Mg, Zn, Fe, Cu, Co, and Mo by a melt-quenching process and the dissolution properties of these glasses were investigated with pH meter and ICP analyzer. In case of the glasses containing the trace elements, effect of trace elements on the dissolutions is not obvious and ignorant the stability of mother glass. Also, the dissolution amounts of each trace elements depend on the mother glass composition and the quantity of each trace element, and mother glasses determined the dissolving velocity of chemical elements.

Distribution channel decisions involve long-term commitments with other firms that are very difficult to change or replace. In particular, marketing channel decisions in emerging markets are much more complicated due to unfamiliar conditions and problems such as lack of market data and distribution systems. Therefore, when a company considers changing or introducing a marketing channel in an area, it is much more difficult to judge its effectiveness in an emerging market than in a developed market. In this study, we investigate the development process of a new direct marketing channel of Hongfu Fertilizer Company (hereafter Hongfu), a medium-sized Chinese fertilizer manufacturer, and propose an approach to test the feasibility of this new marketing channel in the Chinese rural market. We measure the effectiveness of Hongfu's new marketing channel from two perspectives: i) from customers' perspective through direct responses of farmers, which showed that a new channel can increase the convenience and lower the purchasing costs for the farmers, and ii) from the company's perspective, by calculating the incremental profit of the company using the expansion factor (T/Q) method, which suggested that the execution of Hongfu's strategy to expand a new marketing channel will result in an increase in profits. The results of this study contribute to the development of a methodology to test the feasibility of a new direct marketing channel in the emerging markets such as the Chinese rural market. Traditional and indirect distribution channels in emerging markets are generally not very efficient and difficult to change. Especially, in emerging markets, like the Chinese rural market, the methods of testing channel feasibility must be different from that of developed markets. Considering market situations, market experiments can be more effective then systematic market surveys in testing channel feasibility in emerging markets. This study implies that managers must learn to cope with a transition from the traditional marketing channels in emerging markets. With the development in farmers' understanding of marketing concept, the transition from traditional marketing channel is unavoidable for all firms. Farmers in China are generally very conservative, however, their buying behaviors are changing. Therefore, fertilizer companies should try to adjust in accordance with farmers' demand characteristics that the efforts to meet the economic needs of farmers with new marketing channels as well as trust building are critical in the near future.

This study was carried out to investigate the effect of forms and levels of nitrogen fertilizer on plant growth and essential oil production of Agastache rugosa. Calcium nitrate had more influenced on length and width of leaves and lateral branch length than did urea. When nitrogen fertilizer level was increased from 12 kgN/I0a to 24kgN/I0a, plant growth was stimulated and dry matter of leaf and inflorescence were increased. Top dry matter of plant with calcium nitrate treatment (38.4 g) was heavier than that of urea treatment (32.8 g). Interactions among accession and nitrogen form and nitrogen rate were not significantly different for top dry matter. The forms and rate of nitrogen fertilizer did not affect estragole content. The estragole contents was higher in leaf (91.8%) than that of inflorescence (81.3%). While the essential oil content was not affected by different nitrogen forms, nitrogen level affected the essential oil contents positively by increasing dry matter. Essential oil yield was not affected by accession or nitrogen form, but by nitrogen rate. With increasing N application from 12kgN/I0a to 24 kgN/I0a, essential oil yield was increased by 95.8 %.

A fertilizer mixed with an electron beam irradiated sewage sludge and a starfish powder was developed. By the irradiation of sewage sledge, it could be hygienic from harmful microorganism and be free from Rely nucleonic Aromatic Hydrocarbons (PAHs). The quality of fertilizer mainly consisted of electron beam irradiated sewage sledge could be enhanced by addition of starfish powder rich in organic calcium ion. The growth rate for a grass and a rose tree was enhanced about 35% when a fertilizer applied. By the development of new type of fertilizer, a large amount of sewage sledge and star fish con be utilized as a fertilizer.

Establishment of a new concept of environmental friendly livestock manure management is required based on the facts. But now liquid fertilizer quality in korea shows a large difference among regions and the regulations are uncertain. Focusing on precedent study on main level-grading factors of liquid fertilizer quality certification, the study collected laws and standards related to liquid fertilizer of livestock manure at home and abroad and produced evaluation standards. Liquid fertilizer was divided into four factors (fertilizing value, harmfulness, stability and uniformity). According to each item, scores were awarded based on 16 details: fertilizing value (Nitrogen concentration, the whole concentration of Nitrogen, Phosphoric acid and Kalium), harmfulness (heavy metals, pathogenic microorganism and antibiotics), stability (maturity degree and odour), uniformity (EC, BOD, SS, moisture content and salt). The grade of liquid fertilizer, A (42~48), B (34~41), C (26~33) were rated using total scores.

저농도 SCB(Slurry Composting Biofiltration)액비 시비가 생장 및 결실특성에 미치는 영향을 알아보고자 접목 7년생 '축파(Tsukuba)' 품종을 대상으로 SCB액비, 화학비료, 유기질비료, 무처리구 등 4처리를 관행 시비량에 준한 시비 처리로 2008년부터 2009년까지 2년간 생장 및 결실특성을 각각 조사하였다. 수고 및 근부직경의 생장은 전년도에 비해 화학비료와 SCB액비 처리구에서 각각 8.18%와 26.93%, 8.04%와 25.90%의 증가량을 보였으며, 착구부 직경에 대한 기부직경의 비는 화학비료 처리구를 제외하고 전년도에 비해 모든 처리구에서 감소되었다. SCB액비 처리구에서 착과율이 86.25%로 높게 나타남에 따라 SCB액비가 생장과 수세에 기여하는 양료 역할을 하는 것으로 판단되며 새로운 비종으로서 대체 효과가 있는 것으로 나타났다.

The lecturer pointed the agriculture in change brought about population bomb and economic development, and he appealed the scientists of soil and fertilizer to make proposals for establishing their constructive attitudes toward the situations of agriculture. The points emphasised by the lecturer for the improvement of future food situation were: fox example the elucidation of the ancient agricultural technology of Korea which is a important attempt for development of agricultural technology of Korea and Japan, and soil improvement with special attention to the efficiencies of phosphate, silicate, cations and trace elements. He showed some Japanese examples of natural pollution as both of a sufferer and an assailant of agriculture which are resulted from the high economic development, and some methods of solution, for example active application of legumes capable for fixing atmospheric nitrogen to wasted soils. He also pointed the need of lower consumption of energy and resources, and new understanding of wild plant species for the future agriculture. Some methods of other fields of sciences were emphasised for developing the soil and fertilizer researches.

Phosphate glasses were prepared by melting quenching process, and glass formation and dissolution properties were studied. The glass forming region in the $K_2O-CaO-P_2O_5$ system is quietly agreed with the report by Mazurin OV et al. with $M_2O-M'O-P_2O_5$ system (M : monovalent cation, M'divalent cation). Conditionally these glasses have solubility from absorbing the moisture or water and then release elements with trace elements, and the thermal and chemical properties were controllable by the $CaO,\;K_2O,\;P_2O_5$ contents. In the abnormal glass properties, this paper showed the possibility the present glasses can be a good candidate for one component of the slow released agriculture fertilizer.
