논 조건의 포트규모에서 유기질 비료로 화학비료 밑거름량을 대체하기 위해 벼의 정조수량, 쌀 품질 기준인 단백질 함량, 토양 화학적 특성에 미치는 영향을 조사하였다. 벼 생산에 적정인 유기물함량을 지닌 토양 1에서 벼의 생산량은 다른 처리구보다 70 %, 100 %에서 높았다. 벼 생산에 적정보다 높은 유기물함량을 지닌 토양 2에서 벼의 생산량은 NPK, 유기질비료 30%, 70%, 100%, 300%에서 차이가 없었다. 쌀 품질에 대한 단백질 기준이 7 % 이하를 적용할 때 유기질비료 3종(혼합유기질비료, 혼합유박, 유기복합)의 처리구 중에서 70 %, 100 % 처리구가 쌀 품질의 단백질 기준에 적합하였다. 유기질비료 30 %, 70 %, 100 %, 300 % 처리에서 유기물 함량, 암모늄태 질소 및 전기전도도는 NPK 처리와 유사한 경향을 보였다. 이러한 결과로부터 표준 질소 밑거름 시용량의 70 ~ 100 % 수준으로 유기질 비료 3종에 대해 투입하는 것이 농경지의 적절한 양분을 유지하고 쌀의 수확량과 품질을 유지하는 좋은 방법이라 판단된다.

Organic amendment practices can influence diversity and activities of soil microorganisms. There is a need to investigate this impact compared with other types of materials. This study was carried out to evaluate the long term effects of chemical and organic fertilizer on soil microbial community in upland field. During the last 11 years green manure, rice straw compost, rapeseed cake, pig mature compost, NPK, and NPK + pig mature compost were treated in upland soil. Organic fertilizer treatment found with high bacterial colony forming units (CFUs) as compared to chemical and without fertilizer treatment. There was no significant difference in the actinomycetes and fungal population. The average well color development (AWCD) value was the highest in green manure and, the lowest in without fertilizer treatment. Analyses based on the denaturing gradient gel electrophoresis (DGGE) profile showed that rice straw compost and pig mature compost had a similar banding pattern while rapeseed cake, NPK, NPK + pig mature compost and without fertilizer treatment were clustered in another cluster and clearly distinguished from green manure treatment. Bacterial diversity can be highly increased by the application of organic fertilizer while chemical fertilizer had less impact. It can be concluded that green manure had a beneficial impact on soil microbial flora, while, the use of chemical fertilizer could affect the soil bacterial communities adversely.

An experiment was set to understand the seedlings growth and nodulation capabilities of five potentially important leguminous agroforestry tree species of Bangladesh in response to application of organic fertilizer. Study was carried out in nursery bed on the seedlings of Acacia mangium Willd., Acacia hybrid, Acacia auriculiformis A. Cunn. ex Benth, Albizia lebbeck (L.) Benth. and Leucaena leucocephala (Lam.) de Wit. after sowing their seeds in polybags filled with different medium. Farmyard manure or decomposed cow dung was applied as the source of organic fertilizer with other potting media. The growth and nodulation performance of seedlings of the selected species were measured three moths after the first seed was emerged. The different soil: organic manure ratios' used during the experiment were, 1:1, 2:1 and 3:1. The effects of organic fertilizer on growth and nodulation were compared to that of seedlings grown in control. The results revealed a positive correlation between seedling growth and the different doses of organic fertilization (i.e. seedling growth was enhanced significantly with different treatments containing higher proportion of organic fertilizer). In few cases a negative effect was observed after applying higher levels of organic manure. It was also apparent that the nodulation in terms of nodule number and size was inhibited significantly by the application of organic fertilizer.

This experiment was conducted to investigate the effect of animal stable manure on the dry matter yield, botanical composition, crude protein content rates, in vitro digestibility and soil characters with treatments, which were divided into cattle manure, swine manure and poultly excreta of 375 and 750kg/lOa, respectively. The results obtained were summarized as follows: 1. A comparison made on the grass yield for one year period following the termination of the experiment did not indicate any signification in the yield of dry matter difference between chemical fertilizer treatment and 750kg/10a of organic manure. 2. Botanical composition was not shown an increasing of weed or bare land in organic manure of 375 and 750kg/lOa application during the whole period of growth. 3. Crude protein content and in vitro digestibility were shown an increasing tendency according to the increase of organic manure application. 4. Crude protein yield in organic manure of 750kg/10a was not a large difference compared with chemical fertilizer treatment. 5. Soil composition of organic manure had higher than the soil composition of chemical fertilizer treatment, which was shown an increasing tendency according to the increase of organic manure. 6. Therefore, It was suggested that the effect of organic manure on dry matter yield, botanical composition was similar to chemical fertilizer treatment and soil composition of organic manure had higher organic matter, available phosphate, potassium and C.E.C than the soil composition of chemical fertilizer treatment.

Nowadays, sustainable and environment-friendly agriculture has become an important issue all around the world, and repeated applications of mineral and/or organic fertilizer will probably affect mineral nutrient dynamics in soil in the long term but only a limited number of observations are available. This study was carried out to investigate whether there is any influence of different fertilizer management for red pepper (Capsicum annuum L.) cultivation on soil physicochemical properties, leaf mineral content, yield and fruit quality in the aspect of long-term practice in open field condition. NPK, NPK+compost, compost only, and unfertilized control plot were included in the treatments. The application of chemical fertilizer and/or compost repeated annually for 17 years from 1994 to 2011. Soil organic matter content was higher in compost treatments than in no-manure treatments. Available phosphate and the yield of red pepper were highest in NPK+compost treatment followed by NPK (chemical fertilizer), compost, and control. The results indicate that in the long term, nitrogen supply is still needed for increasing red pepper yield, but reduction in the use of chemical fertilizer could be also possible with the proper application of compost.
