Abstract
The purpose of this study is to investigate coffee farms in Amami Oshima, Kagoshima Prefecture, among the coffee farms in Japan, and to show the farm type and coffee cultivation environment.We conducted interviews with the farm owners and surveys throughout the four seasons using precision equipment at two coffee farms on Amami Oshima.The farms had the following characteristics: Coffee was grown on improved land in mountainous areas, which had previously been used for growing other agricultural products, and forests, windbreaks, and windbreak fences were used to protect against the wind.In addition, coffee and bananas were planted in alternating rows to suppress wind and reduce solar radiation, and fallen tree branches and leaves contributed to the development of good soil.The coffee growing environment with good tree vigor and fruit set had the following characteristics: Wind was controlled by windbreaks and fences, and temperatures were high in summer and low in winter.In addition, compared to previous studies, coffee was grown under high humidity and low light intensity, and the soil environment had a slightly low pH and EC value.
