Abstract

Tsugaru area in Aomori prefecture is located in a cold snowy region and is known as a major apple producing area. The purpose of this study is to understand the mass and energy transport phenomena in apple orchard soil in gravelly brown forest soil by applying the field monitoring system (FMS). The author observed the characteristics of year-round changes in soil moisture, electrical conductivity and soil temperature from 2016 to 2020. Focusing on the characteristics of soil moisture, it was found that the apple orchard soil was in the process of drying during the 4-years observation period because of the cumulative total soil moisture change (ΣΔTSM) tended to increase. Regarding the characteristics of electrical conductivity (EC), a steeply and apparently increase in the soil solution EC with time was observed during the period when the matric potential was below -4,000 cmH₂O (corresponding to pF 3.6), which is the measurement limit (θ < 0.1 cm³/cm³). In addition, it was showed that the effect of fertilization in early spring was difficult to appear to the soil solution EC. Regarding the characteristics of the soil temperature, the fluctuation was small compared to the change in the soil temperature during the non-snowy period due to a heat insulating effect of snow during the snow cover period. It was found that the soil temperature at a depth of 10 to 100 cm decreased within a short period at the end of the snowmelt period, and the decrease in soil temperature became more remarkable in the deeper part due to percolate the snowmelt water.
