In a soil of Jeonnam series in the reclaimed hilly area of Jeonbug district some field experiments on the improvement of fertility for the increased yield of red-pepper were conducted. The pH was highest in the plots treated the fused phosphate and the slake lime at the same plot, and next, the slaked lime treated plots ; the organic matter content was much increased in the amino acid fermentation residue treated plots and the same treated plots of amino acid fermentation residue and fused phosphate ; the available phosphate content was increased in the fused phosphate treated plots and the same treated plots of fused phosphate and slaked lime. while the phosphorus absorption coefficient was decreased ; the lime requirement was much decreased in the slaked lime treated plots and the same treated plots of slaked lime and fused phosphate compared with the other treatments ; the great increase of C. E. C was observed in the same treated plots of amino acid fermentation residue and fused phosphate, and then the amino acid fermentation residue treated plots, the same treated plots of fused phosphate and slaked lima, the fused phosphate treated plots in the order of the degree of increase. The yield showed the significant difference between two varieties, and thus Daejang-kyung variety(Fl) was more increased in yield than Imsil local variety in general. Regardless of variety the greatest increase in yield was observed in the same treated plots of amino acid fermentation residue and fused phosphate, and then the amino acid fermentation residue treated plots, the same treated plots of fused phosphate and slaked lime, the fused phosphate treated plots, the slaked lime treated plots in the order of the degree of increase. Considering the result of economic analysis, the production cost of Daejang-kyung was higher than that of Imsil local variety, but regardless of variety the net income was high in a11 treated plots compared withe control piots. The greatest increase of net income was observed in the same treated plots of amino acid fermentation residue and fused phosphate, and then the amino acid fermentation residue treated plots, the same treated plots of fused phosphate and slaked lime, the fused phosphate treated plots, the slaked lime treated plots in the order of the degree of increase.

Clay-Organic matter complexes of various organic matter Ievels were prepared and incubated at 30±2℃ for 38 days in the laboratory. The pH, Eh, Fe and NH_4-N changes of these clay- organic matter complexes and the aspect of absorption of Fe-EDTA added to these clay-organic matter complexes during the incubation were studied. The results can be summarized as follows: 1. The pH as a whole showed a tendency to be increased as incubation day progressed. Highly significant differences in pH values were observed among the plots except the 6% and 9% plots. 2. The Eh showed a tendency to be decreased for the first 20 days of incubation and increased a little after the 20th day. The Eh valves of the plots with organic matter were very much lower than those of the plot without organic matter, showing highly significant differences in Eh values among plots except the 6% and 9% plots. 3. Much more Fe, 20 times as much Fe at the highest level, was released from the plots with organic matter than from the plot without organic matter. No significant difference in Fe values was observed among the plots. 4. The NH_4-N value was rapidly increased in the early days of incubation and then decreased after the 11th day. Significant differences in NH_4-N values were observed among the plots with organic matter. 5. A negative correlation was observed between Eh and Fe and between Eh and NH_4-N, a highly negative correlation between pH and Eh, and a positive correlation between pH and Fe. Ⅱ. Test on the Absorption of Iron to Clay-Organic matter Complexes. 1. The pH showed almost the same tendency exhibited in the previous experiment. 2. The Eh also showed the same tendency exhibited in the previous experiment, but the Eh values in the plots with organic matter were a little lower than those observed in the previous experiment. 3. Most of the absorbed Fe-EDTA was absorbed to the clay-organic matter complexes in the very beginning of incubation. The absorption indices were greater in the plots with organic matter than those in the plot without organic matter and the absorption indices were increased with the increase of organic matter level. 4. A highly negative correlation was observed between pH and Eh and a highly positive correlation between pH and Fe.

The distribution, composition, formation, transformation and characteristics of clay minerals in clay fractions of 14 representative soils in the Gimje-Mangyeong plains were investigated to explain the genesis of paddy soils through the investigation of the formation and transformation of the clay minerals of paddy soils of Korea, and to obtain some basic data for the increase of rice productivity, paddy soil management practices and the improvement of fertility of paddy soils of Korea through the investigation of the functions of the clay minerals of these paddy soils. The results are summarized as follows: 1. The major clay minerals present in the paddy soils in the Gimje-Mangyeong plains are composed of halloysite, vermiculite and illite, and can be grouped into four on the basis of their relative contents. 1) Soils which contain halloysite as a major mineral, and vermiculite and illite as minor ones; Jisan Ap_1, B_3g, Baeggu Ap_1, Sindab Ap_1, C_2g, Gongdeog Ap_2, B_2g, Bongnam Ap_1, B_1g, Buyong Ap_1, Gimje Ap_2. 2) Soils which contain halloysite and vermiculite as major minerals, and illite as a minor one; Hwadong Ap_1, B_2t, Geugrag Ap_2, Baeggu B_2g, Suam Ap_1, Jeonbug Ap_2. 3) Soils which contain vermiculite as a major mineral, and halloysite and illite as minor ones; Suam C_2g, Gongdeog C_3g, Bongnam C_3g, Gimje B_2g. 4) Soils which contain vermiculite, illite and halloysite at the same rate of composition; Geugrag B_22t, Honam Ap_2, B_22tg, B_23tg, Buyong B_21tg, Jeonbug B_22g, C_1g, Mangyeong Ap_1, B_2g, C_2g, Gwanghwal Ap_2, C_2g. Small amounts of Iron mineral(goethite), gibbsite, mixed layer mineral of illite-vermiculite and amorphous Fe_2O_3 are also present with primary minerals, quartz and feldspar. 2. Among the factors influencing the formation of clay minerals parent material and topography are believed to have been the most influential ones that affected the formation of the clay minerals of these paddy soils, whose original parent materials are composed mainly of granite and granite gneiss. Thus, in the soils derived from Local alluvial deposits which are located near the original parent materials and in the interior land soils derived from Alluvial and Fluvio-marine deposits halloysite is dominant; in the river-side anb/or the coastal plain soils derived from Alluvial and Fluvio marine deposits which are located far from the original parent materials vermiculite is dominant. Also, because the compositon of deposited parent materials varied with the topography the distribution of clay minerals varied with the type of deposition. Especially, the transformation of clay minerals by sea water is observed in the coastal plain soils derived from Fluvio-marine deposits; in the interior land soils a trace of influence of sea water is noticed only in the lower horizons. 3. Very poor formation of gibbsite in those soils can be explained by the facts that desilication in these soils was very slow and weak in spite of the particular flooded condition, and most of Al was fixed in the interlayers of vermiculite during its formation from illite. 4. The relationship between soil clay mineral and the c.e.c. of clay fractions of these soils is Just the same as that between pure clay mineral and c.e.c., and vermiculite shows the greatest c.e.c., illite the medium and halloysite the smallest.

嚴大翼 전북대학교 농업과학기술연구소 1977 農大論文集 Vol.8 No.-

In order to evaluate the residual effect of the improved fertility in a red-yellow acid soil of Yesan Series in a reclaimed hilly area of the Honam district winter naked barley was cultivated as a second crop in the field where red-pepper had been cultivated as a first crop. 1. The fertility factors of the first crop field were not significantly changed even after the harvest of the second crop of naked barley, while exchangeable bases and C.E.C. increased a little. 2. As much as 40.3 per cent increase in yield was obtained from the composite treatment plots as compared with that from the N-P-K treated plots. The same increase in yield as in the first crop was obtained from the other treated plots. 3. The yield from the N-P-K treated plots was 74.2 per cent of the average yield from the cultivated uplands in Iri area, while the yield from the composite treatment plots increased by 4.1 per cent. 4. This indicates that the yield of naked barley can be increased with improvement in fertility factors in a red-yellow acid soil of low fertility in a reclaimed hilly area.

In order to find out the application effect of commercial organic fertilizer on the germination rate of ginseng seed, growth of ginseng plant and changes of the physicochemical properties of soils, a Miwon organic fertilizer, byproduct of amino acid fermentation, was applied to the ginseng nursery bed. The application rates of Miwon organic fertilizer were 0kg-N from organic fertilizer and 30kg-N from wild grass compost per 10a as control(namely 0kg-N/10a), 2.5kg-N and 27.5kg-N/ 10a(2.5kg-N/10a) 5.0kg-N and 25kg-N/10a(5.0kg-N/10a), 10kg-N and 20kg-N/10a(10kg-N/10a), 15kg-N and 15kg-N/10a(15kg-N/10a) respectively, The obtained results are as follows: 1. The germination rate of ginseng seed were better in the plots that received 2.5kg, 5.0kg and 10kg-N/10a as compared with control plot. However no difference was found on germination rate between control and 15kg-N/10a, 2. The higher rate of missing plant was found in the 15kg-N/10a plot that showed poor growth. However control and 10kg-N/10a plot showed similar rate of missing plant. The best result, lower rate of missing plant, was obtained in the order of 5kg-N and 2.5kg-N/10a respectively. 3. The significant heavier ginseng root weight was obtained in 5kg-N/10a and 10kg-N/10a plot. However the root weight was decreased in the order of 2.5kg-N/10a, control, 15kg-N/10a. 4. In the physicochemical changes of soils between control and organic fertilizer treated soil before and after harvesting the increment of pH, C.E.C. and organic matter content along with the rate of organic fertilizer application were found. There were significant correlation between nitrate nitrogen and the rate of organic fertilizer application. 5. In the view points of germination rate, missing rate of plant and yield of ginseng root, it can be stated that the best result could be obtained from the plot that received 10kg-N/10a from Miwon commercial organic fertilizer and 10kg-N/10a from wild grass compost.
