우리나라 최남단에 위치한 제주도에 가장 많이 분포하고 있는 화산회 밭 토양과 비화산회 밭 토양에 가축분 퇴비를 0, 50, 100, 150 ton/ha 해당량을 시용한 후 토양 부식의 함량 변화를 조사하여 문제점을 살펴본 결과는 다음과 같다. 부식의 분포도는 화산회 토양은 대부분 A type이었으며 일부 밭토양에서 B type에 속하여 화산회 토양은 부식화가 진행되었음을 알 수 있었으며 비화산회 밭토양은 대부분 Rp, B type으로 존재하여 동일한 결과를 얻을 수 없었다. 질산태 질소 함량과 부식함량과의 관계는 화산회 토양은 $R^2=0.5263$, 비화산회 양은 $R^2=0.524$의 정의 상관관계를 나타내었다. 탄소의 함량과 부식 함량과의 관계는 화산회 토양은 $R^2=0.469$, 비화산회 밭 토양은 $R^2=0.550$의 정의 상관관계를 보이고 있다.

In Jeju island, the southernmost island of Korea, the field soils are mostly consisted of volcanic and non-volcanic soils. Animal manures of 0, 50, 100, and 150 MT/ha were treated to analyse the humus content changes by application amounts and the soil types. The results are as follows; Humus distribution type was A in the most of the volcanic soils while a few soils was type B, and it was possible to confirm that the humus process has occurred in the soils. Most of the non-volcanic soils was Rp and B type, therefore, the humus content change pattern was different from the volcanic soils. The nitrate-nitrogen content and the humus content showed positive correlation of $R^2=0.5263$ in the volcanic soils, while that of non-volcanic soils was $R^2=0.524$. The carbon content and the humus content showed positive correlation of $R^2=0.469$ in the volcanic soils, while that of non-volcanic soils was $R^2=0.550$.
