This study was carried out to investigate the effect of slurry composting and biofiltration (SCB) liquid manureapplication on shoot growth, fruit qualities and soil chemical properties in peach orchard. SCB liquid manurewas fertigated ten times from April to October in SCB plot, whereas chemical fertilizer was treated two timesas basal and additional fertilizers in control plot. The shoot growth, leaf nitrogen and potassium content, soilexchangeable K, fruit weight and yield were higher in SCB plot than in control. Soluble solid content andacidity, soil organic matter, soil available phosphate and soil exchangeable Mg showed no significantdifference between treatments, and the leaf calcium and magnesium content were lower in SCB plot than incontrol. In conclusion, fertigating SCB liquid manure in peach orchard has positive effects on fruit weight andyield, and it is suggested that periodical soil testing is needed because of the possibility of K accumulation inSCB liquid manure treated soil when the orchard is fertigated based on the soil nitrogen content.

시설 하우스 토마토재배에서 돈분뇨 액비와 화학비료의 관비 처리 효과를 알아보기 위하여 무비, 질소 기준으로 돈분뇨 액비 26 mg L<SUP>-1</SUP>, 52 mg L<SUP>-1 </SUP>및 화학비료 52 mg L<SUP>-1</SUP> 4처리를 하여 토마토 수량, 생육, 무기성분함량, 양분흡수량, 양분이용률 및 토양 화학성에 미치는 영향을 알아보았다. 돈분뇨 액비와 화학비료 관비 처리는 수량과 생육에 차이가 없었으며 돈분뇨 액비 26 mgL<SUP>-1</SUP> 처리에서 수량이 감소하는 경향을 보였다. 돈분뇨 액비와 화학비료 처리에 비해 잎과 뿌리의 질소와 칼륨함량은 무비에서 낮았으나 뿌리와 줄기의 인산함량은 무비에서 높았다. 칼슘함량은 잎에서 처리간에 차이가 없었으나 뿌리와 줄기는 돈분뇨 액비 52 mg L<SUP>-1</SUP> 처리가 높았고 과실내 칼슘함량은 화학비료 52 mg L<SUP>-1</SUP> 처리가 낮았다. 양분 이용률은 질소 15.8~36.7%, 인산은 3.0~6.3%, 칼륨은 29.2~43.3%로 칼륨, 질소, 인산 순으로 낮았다. 토양 화학성 중 pH는 돈분뇨 액비 처리가 화학비료 처리보다 높았고 질산태 질소함량은 화학비료 처리가 돈분뇨 액비 처리보다 증가하였다. 치환성 칼륨함량은 돈분뇨 액비와 화학비료 52 mg L<SUP>-1 </SUP>처리구가 높았으며 칼슘과 마그네슘은 처리간에 차이가 없었다. 결과적으로 토마토 관비 재배에서 토양 검정에 의한 돈분뇨 액비 시용은 화학비료 질소와 칼리를 대체하여 이용할 수 있을 것으로 판단되었다. This study was conducted to evaluate fertigation effects of pig slurry (PS) and chemical fertilizer (CF) in tomato by analyzing the growth and yield, nutrient content and uptake, nutrient use efficiency, and soil characteristics in greenhouse cultivation. The treatments compared were; no-fertilizer, two different levels of PS (26 mg L<SUP>-1</SUP> and 52 mg L<SUP>-1</SUP>), and a control treatment of chemical fertilizer. There was no significant difference in growth and yield between PS and CF treatments. however, yield reduction was observed in PS 26 mg L<SUP>-1</SUP> treatment. The N-utilization efficiency in CF treatment was similar to that of PS 52 mg L<SUP>-1</SUP> treatment. Nutrient utilization efficiency decreased in order of potassium (K), nitrogen (N), phosphate (P) with 29.2~43.3% in K, 15.8~36.7% in N, and 3.0~6.3% in P. In soil chemical characteristics, soil pH in PS treatment was higher than in CF treatment. In contrast, nitrate content in soil was higher in CF treatment than in PS treatment. The content of exchangeable K in soil was higher in PS and CF 52 mg L<SUP>-1</SUP> treatments. There was no significant difference in exchangeable Ca and Mg among those treatments. Therefore, it can be concluded that chemical fertilizers can be substituted by PS based on soil chemical analysis in tomato fertigation culture.
무기질 및 유기질 비료 시용이 고추 수량과 토양화학성에 미치는 영향

고추밭에서 화학비료 및 퇴비의 14년간 연용 및 결제처리 후 토양화학성 및 수량 변화와 양분 흡수량을 조사한 결과는 다음과 같다. 토양화학성 변화 중 유기물함량은 퇴비 처리시 매년 1.11-1.17g·㎏<SUP>-1</SUP>씩 증가하였고 무퇴비구에서도 매년 0.51-0.55g·㎏<SUP>-1</SUP>씩 증가하였다. 유효인산함량은 매년 N₀P₀K₀ 처리에서 3.6㎎·㎏<SUP>-1</SUP>, NK+퇴비 처리에서 16.㎎·㎏<SUP>-1</SUP>, NPK+퇴비 처리에서 45.㎎·㎏<SUP>-1</SUP>씩 증가하였다. 치환성 칼륨함량은 N₀P₀K₀ 처리에서 0.22c㏖·㎏<SUP>-1</SUP>까지 감소하였으며 NPK 처리는 0.50-0.71cmol·㎏<SUP>-1</SUP>에서 안정되어 평형을 이루었다. 치환성 마그네슘함량은 NK+퇴비 및 N₀P₀K₀에서 낮 았다. 고추의 양분흡수량과 수량은 N₀P₀K₀<PK+퇴비<NK+퇴비<NPK=NP+퇴비≤NPK+퇴비 순으로 많아 질소 비료가 고추의 수량 및 생육에 크게 영향을 미치며 인산은 흡수량이 적어 인산 축적을 방지하기 위하여 인산 시비량을 줄 일 필요가 있다. This study was conducted to investigate the effects of mineral and organic fertilizer application on pepper (Capsicum annuum) yield and soil chemical properties for 14 years from 1994 to 2007. For the experiment, experimental plots were established on a sandy loam soil with six treatments, which consisted of no fertilization (N₀P₀K₀), N+P+K standard fertilization (NPK), N+P+K+compost (NPKC), P+K+compost (PKC), N+P+compost (NPC), and N+K+compost (NKC). During the 14-yr experimental period, organic matter contents in soil increased continuously at the rate of 1.11-1.17 g·㎏<SUP>-1</SUP>·yr<SUP>-1</SUP> in the treatments with compost applications and 0.51-0.55 g·㎏<SUP>-1</SUP>·yr<SUP>-1</SUP> in treatment with no compost application. The soil available phosphate in N0P0K0 treatment increased at the rate of 3.6 ㎎·㎏<SUP>-1</SUP>·yr<SUP>-1</SUP>, which was insignificant compared to those in compost applied treatments such as 16.1 ㎎·㎏<SUP>-1</SUP>·yr<SUP>-1</SUP> in NKC and 45.0 ㎎·㎏<SUP>-1</SUP>·yr<SUP>-1</SUP> in NPKC. As cultivation periods for pepper was extended, exchangeable potassium concentrations in soil tended to decline continuously. But, exchangeable potassium content in soil showed no further decline at the level of 0.22 c㏖·㎏<SUP>-1</SUP> in N₀P₀K₀ and 0.50-0.71 c㏖·㎏<SUP>-1</SUP> in NPK treatment. Fruit yield and the amount of nutrient absorbed by pepper increased in the following order: N₀P₀K₀ < PKC < NKC < NPK ≒ NPC < NPKC, indicating that hot pepper shows the greatest response to nitrogen. From the results of long-term mineral and organic fertilizer application, it is obvious that nitrogen is the important nutrient for production of pepper fruit. The amount of phosphate fertilization recommended currently for pepper should be reduced to avoid accumulation of phosphate in soil.
