“…2) were counted several times until the end of July. Most of the volunteer potato tubers were left at 0-0.3 m depth after the harvest in autumn (Yazaki et al 2013). We confirmed that all the potato tubers buried in this soil layer sprouted on the ground up to July at another field located in the central part of Tokachi (143°05ʹE/42°53ʹW).…”

“…Yazaki et al (2013) reported the threshold of soil temperature to kill potato tubers was -3°C. Soil temperatures at 0.1 m in depth dropped below -3°C only at Shihoro in 2010-2011 (T −0.1 min in Table 1; T −0.1 min means minimum soil temperature at 0.1 m in depth).…”

“…Soil temperatures at 0.1 m in depth dropped below -3°C only at Shihoro in 2010-2011 (T −0.1 min in Table 1; T −0.1 min means minimum soil temperature at 0.1 m in depth). Soil temperatures calculated by Yazaki et al (2013) Table 1). Therefore, potato tubers of Shihoro in 2010-2011 could have been killed by the cold temperature in winter.…”

“…Low temperature is a factor in killing potato tubers. Yazaki et al (2013) implied that other factors kill potato tubers because substantial numbers of potato tubers were killed in fields where the soil temperature did not drop below -3°C. Some researchers have reported that potato tubers might rot under high soil moisture conditions (Hagiwara and Yogo 1945;Letnes 1958).…”

In situ observations were conducted at eight fields in the Tokachi region of the northernmost island of Japan to assess the effects of soil physical conditions on the survival of volunteer potato (Solanum tuberosum L.) tubers. Statistical analyses revealed a positive correlation between the survival rate and the lowest value of saturated hydraulic conductivity to a depth of 0.5 m, except for data from one field where potato tubers were killed by low temperatures below -3°C during winter and from another field with poor drainage despite high soil permeability to 0.5 m in depth. Incubation experiments indicated that potato tubers survived in saturated soil at 0 and 6°C, which respectively matched soil temperatures during the snowmelt period and 1 week thereafter. This result suggests that potato tubers can survive prolonged exposure to moist surface soil caused by large amounts of snowmelt water during the spring snowmelt period. The incubation experiment results also indicated that potato tubers were killed in saturated soil at 15°C. This temperature was almost equal to the average air temperature during the period when volunteer potato tubers were sprouting in the field. Therefore, this result implies that the potato tubers will be killed after a substantial amount of rainfall during the subsequent warm period at poorly drained fields.

“…Our interpretation can be applied to the case for a recent tendency in early-winter snowfall events and its subsequent decreace in soil-frost depth (Hirota et al 2006;Yazaki et al 2013a). The soil-frost depth was much sensitive to early-winter snowfall under the present climate, which was demonstrated in the difference between the two typical cases.…”

A future change in the soil-frost depth in eastern Hokkaido was assessed with multiple local climate scenarios. The biascorrected downscaled data with an aid of a simple snow-depth model were applied to the empirical estimation from cumulative freezing degree-days (CFD) for days when the snow depth is less than 20 cm. Consequently, as the response to global warming climate that was defined as +2-K world in this paper, the maximum soil-frost depth significantly decreased in the coastal regions along the Pacific and in central Tokachi subprefecture with a slight variation among climate scenarios. Parameter-sweep experiments for two observed cases clarified that the temperature increase would bring the soil warming in the environment where the insulation effect of snow cover does not work at present, while it would bring the soil frosting in the environment where the insulation effect works.(Citation: Inatsu, M., J. Tominaga, Y. Katsuyama, and T. Hirota, 2016: Soil-frost depth change in eastern Hokkaido under +2 K-world climate scenarios. SOLA, 12, 153−158,

Air temperature and sunshine duration for agricultural fields were extracted from 1-km-resolution weather data, and their relationship with winter wheat yield was compared for the adjacent Tokachi and Okhotsk regions of eastern Hokkaido, Japan. Major climatic drivers of winter wheat yield were air temperature during spring and grain-filling period in Tokachi, and sunshine duration during grain-filling period in Okhotsk. The regional difference in the sensitivity of yield to air temperature is attributed to variations in sunshine duration during grain-filling period. In Tokachi, a shorter grain-filling period limits the cumulative sunlight available to plants, because sunshine duration declines from late June to late July. In Okhotsk, yields of winter wheat were attributed to receiving adequate sunlight, although the growth period was curtailed by higher air temperature. We found that different climatic drivers affected winter wheat yield even in adjacent regions. The sensitivity of winter wheat yield to temperature can be determined by a threshold of 4.5 h daily sunshine duration regardless of region. Short sunshine duration during the grain-filling period exacerbated the sensitivity of wheat yield to temperature. Early summer in Okhotsk is characterized by sunnier weather than in Tokachi due to foehn, with respect to the southerly winds. Then, southerly wind was associated with significantly longer sunshine duration in Okhotsk. Regional cloud development affects sunshine duration as the climatic driver of wheat yield.
