Abstract

This study was conducted to determine effects of composted livestock manure application on soil nutrient change. PVC pot $(30\times100cm)$ was filled with either volcanic ash soil (Gujwa series) or non-volcanic ash soil (Aewol series) and the 20 cm surface soils were applied with composted livestock manures of cattle pig and poultry at the rates of 0, 50, 100 and 150 ton/ha, respectively. After 210 days soils samples of phosphate, potassium, calcium, and magnesium affected by application of the compost. The applied composted were equivalent to the application of organic matter of $23\sim111$ ton/ha and nitrogen of $80\sim450$ ton/ha. Availability rate of phosphate after the application of composted livestock manures ranged from 1.6 to 91.7% according to the different composted. It was much higher in the non-volcanic ash soil than in the volcanic ash soil. Availability rate of potassium fractional recovery rate change ranged from 22 to 94% according to the different manures. It was larger in the composted Availability rate of calcium 38 to 93% and $9\sim90%$ in volcanic ash soil and non-volcanic ash soil, respectively, It was higher in the composted manures followed by cattle and composted pig manures. Availability rate magnesium ranged from 12 to 41% and $1\sim9%$ in volcanic ash soil and non-volcanic ash soil, respectively. The rate was higher in the composted poultry manure followed by pig and composted cattle manures.

본 연구는 축분 퇴비시용에 따른 토양중 양분행동 양상을 구명하기 위하여 직경 30 cm 높이 1 m의 PVC pot에 화산회(구좌통) 토양과 비화산회(애월통) 토양을 충진하고 표토 20 cm 깊이로 계분 부숙퇴비, 돈분 부숙퇴비, 우분 부숙퇴비를 0, 50, 100, 150 ton/ha 해당량을 시용한 후 210일이 경과한 후 토양시료를 채취하여 풍건한 후 가축분 퇴비 처리에 따른 토양중 인산, 칼리 및 마그네슘의 유효화율을 조사한 결과는 다음과 같다. 가축분 퇴비의 시용은 통양중 유기물을 $23\sim111$, 질소 $80\sim450$ ton/ha 해당량을 시용하는 효과가 있었다. 가축분 퇴비의 시용에 따른 인산의 유효화율 변화는 $1.6\sim91.7%$로 가축분 종류에 따른 차이가 매우 컸는데 토양별로 비화산회 토양이 화산회토양에 비하여 월등히 큰 것을 알 수 있었다. 칼리의 유효화율 변화는 $22\sim94%$ 범위로 가축분의 종류 및 시용량에 따라 차이가 컸는데 가축분 종류에 따른 유효화율은 계분 부숙퇴비, 우분 부숙퇴비, 돈분 부속퇴비의 순으로 컸다. 칼슘의 유효화율은 화산회 토양은 $38\sim93%$ 비화산회 토양은 $9\sim90%$ 범위로 가축분 종류 및 토양의 특성에 따른 차이가 컸는데 가축분 종류별로 살펴보면 계분 부숙퇴비, 우분 부숙퇴비, 돈분 부숙퇴비의 순으로 컸다.
