국문 초록 (Abstract)

우리나라 시설원예지에서 유효불소 함량에 대한 토양유기물의 상대 기여도를 구명하고자 경기, 충남, 경북, 제주도에서 채취한 시설원예지 토양을 공시하여 얻은 결과는 다음과 같다.
1. 시설원예지의 유효불소 함량은 최저 0.17ppm, 최고 2.24ppm이었고, 육지토양이 0.93±0.62 ppm이었고 제주도 토양은 0.41±0.20ppm이었다.
2. 토양유기물의 함량은 최저 0.46%, 최고 15.20%이었으며, 평균함량은 육지토양이 1.93±1.21%이었고, 제주도 토양은 13.4±1.95%로 육지토양보다 높았다.
3. 표토의 유기물 함량과 유효불소함량 간에 육지토양은 고도의 유의성(r=0.6440**)있는 정상관이었으나, 제주도 토양은 유의성(r=0.5024)이 없었다.
4. 토양유기물이 1단위 증가함에 따라 붕소의 함량은 육지토양이 1.1596 ppm, 제주도 토양은 0.0392 ppm씩 통계적으로 증가하는 경향이었다.
5. 유효붕소 함량에 대한 토양유기물의 기여도는 유기물의 함량이 적은 육지토양에서 높았고, 유기물의 함량이 많은 제주도 토양은 낮았다

This study was conducted to identify the contribution ratio of soil organic matter for an available boron content in plastic film house soils which were obtained from the soils of Gyeong-gi, Chung Nam, Gyeong Buk and Jeju areas.
The results are summarized as follows;
1. Available boron content in plastic film house soils was from 0.07 ppm to 2.24 ppm, average content was 0.93±0.62 ppm(inland soils) and 0.41±0.20ppm(Jeju soil), respectively.
2. The content of organic matter was from 0.46% to 15.20% average content was 1.93±1.21%(inland soil) and 13.4±1.95%(Jeju soil), respectively.
3. The inland soils between organic matter content and available boron content showed a highly positive correlation coefficiency (r=0.6440**), while Jeju soil was positive correlation coefficiency (r=0.5024).
4. The content of available horon, as increasing 1 unit of soil organic matter, was increased as 1.1596 ppm in inland soils, while it was increased as 0.0392 ppm in Jeju soil.
5. The contribution ratio of soil organic matter for avaiable boron content was high in inland soils, which have low content of ofganic matter, while it was low in Jeju soil containing a high content of organic matter.
