Abstract

The investigation was conducted to find out amounts and ratios of N, P and K fertilizers applied on summer Chinese cabbage in 58 farmers' fields of highland area. The application levels of N, $P_2O_5$, $K_2O$, livestock manure and lime fertilizers were 444, 188, 390, 9,920 and $2,160kg\;ha^{-1}$, respectively, for summer Chinese cabbage. The ratios of basal dressing were 48% in N, 46.6% in $K_2O$. The frequencies of top dressing both N and K were 1.7 times. The kinds of compound fertilizers were in the order of 11-10-10+3+0.3 > 11-6-6+4+13+17 > 12-9-11+3+0.3 in basal application and 18-0-18+0.3 > 13-0-13+1+0.3 > 18-0-15+0.3 in top dressing. From the surveyed results, we could estimate that total 4,347 tons of N, $P_2O_5$, and $K_2O$ fertilizers were over used for summer Chinese cabbage by farmers in highland.

고랭지 여름배추 재배농가의 시비실태를 조사하여 시비개선 기초자료로 활용코져 1999~2001년에 58농가를 대상으로 청취조사한 결과, 3요소비료는 추천시비량에 비하여 질소 1.4배, 인산 2.4배, 칼리 2.0배를 시용하고 있었으며, 퇴비는 가축분퇴비 위주로 $9,920kg\;ha^{-1}$을 사용하고 있어 추천량보다도 감비하고 있는 반면, 석회질비료는 $2,160kg\;ha^{-1}$로 추천량에 접근하였다. 농가가 많이 사용하는 복합비료 비종은 기비로 11-10-10+3+0.3 (원예1호) > 11-6-6+4+13+17(쌀맛나) > 12-9-11+3+0.3(원예범용) 등의 순위이었고, 추비는 18-0-18+0.3(벼수비용) > 13-0-13+1+0.3(웃거름) > 18-0-15+0.3(NK마그) 등의 순위였다. 배추농가에서 퇴비는 계분퇴비 >돈분퇴비 >우분퇴비 >생계분순으로 전체 조사농가중 91.4%의 농가에서, 석회는 소석회 >생석회 >석회고토순으로 81%농가가 사용하였다. 고랭지배추 재배면적(10,206ha)을 적용한 총 소요량으로 볼 때 농가시비량의 절감 가능량은 성분량으로 4,347톤(질소 1,265톤, 인산 1,123톤, 칼리 1,959톤)으로 추정 할 수 있었다.
