Abstract
Since volcanic ash soils in Cheju island have high capacities of adsorption and immobilization of phosphate, a relatively high rate of P application has been recommended in citrus orchards for many years and such a large amount of P application could be problematic both in agricultural and environmental point of view. The objective of this study was to test whether arbuscular-mycorrhizae can be used to improve P availability in Cheju citrus orchard soils. Soil, root and leaf samples were taken from 14 citrus orchards of different location and soil texture. Mycorrhizal spore distribution in the soils, mycorrhizal infection ratio on the citrus roots, and mineral nutrients in leaf samples were determined. Numbers of mycorrhizal spore were in the range of
인의 고정이 심한 제주도 토양에서 인 시용량을 줄이고 불용태 인의 이용율을 높일 수 있는 방법으로써 mycorrhizae의 이용 가능성을 검토하기 위하여 제주도 감귤원에서 그 분포 실태를 조사하고 mycorrhizae형성율과 토양의 이화학적 성질 및 감귤 잎의 무기양분 함량과의 관계를 분석하였다. 제주도 내 토성과 위치를 달리한 14개소의 감귤원에서 감귤 뿌리를 포함한 토양 시료를 채취하여 조사한 결과 건조 토양 100g당
