Finnish soil temperature regimes have been pergelic, cryic, and frigid, where pergelic is coldest and unsuitable for agricultural use. The study monitored soil temperatures at a soil depth of 50 cm in 2010, 2013, 2016 and 2019 to look at how the soil temperature regimes have changed. Probably, as a result of climate warming the soil temperature regimes in Southern Finland in the Helsinki region at a latitude of 60–61°N have raised from cryic and pergelic to warmer mesic over a period of ten years.

Three-inch soil cores were taken in triplicate from areas that had been burned in 1943, 1945, 1945 and 1951, and from corresponding unburned areas present within each burned-over area.Studies carried out on these cores taken from the 0 to 3-inch layer of soil revealed that, as a result of burning, there were decreases in total porosity and non-capillary porosity and an increase in capillary porosity. Field investigations showed that there was a decrease in the infiltration rate of burned soils and that there was an increase in soil temperature at a depth of 3 inches in burned soils.

Bark and wood residue, commonly referred to as "hog fuel" or "hog," from a portable pulp chipper was deposited on aspen cutblocks in replicated 10 x 10 m treatment plots during winter logging operations in northeastern British Columbia. The treatments emulated disposal of hog under conditions that simulated on-site chipping operations. Three different rates of hog disposal were applied; 34, 68 and 102 kg m-2, and three cutblocks were treated, one each during February of 1997, and March of 1998 and 1999. We originally hypothesized that the deposition of hog would lower soil temperatures in the treated plots and reduce aspen sucker density during the following growing season. However, our observations showed an initial lag in soil warming in the treatments followed by temperature levels that rose above that exhibited in the control plots. Higher soil temperatures were correlated with greater rates of hog disposal. Increased suckering was not observed in response to higher soil temperatures and stem densities decreased as hog application rates increased.

The immediate effects of wildland fire on soil have been well documented. However, we know much less about the longer-term effects and their implications for plants. Post-fire soil temperature regimes, for example, have received relatively little research attention, despite potential effects on plant phenology and establishment. Using portable temperature datalogger units (iButtons), we conducted an experimental study to assess how fire severity (measured in terms of litter and duff consumption) influences biologically relevant temperature parameters such as diel minimums, maximums, means, and ranges. We also used these data to calculate cumulative soil growing degree days (GDDs). The study was conducted during the early to mid-spring to capture the transition from dormant season to growing season. Results indicate that mean and max soil temperatures increase in the weeks after fire, with the most pronounced effects in the higher severity treatments. By the end of the 40-day study period, soils in the high severity burn treatment had accumulated 72 GDDs, compared to 17.9, 13.6, and 1.4 in moderate, low, and control treatments, respectively. These findings indicate that fire severity has significant and persistent effects on post-fire soil temperature regimes, and this likely has implications for the post-fire vegetation response.

Abstract Recent studies have shown marked effects of soil temperature on growth, development, and seed composition of peanut. Knowledge about how soil temperature affects pods and roots separately could provide useful information for field management and genetic manipulation. To facilitate such investigations, a technique was developed which allows imposition of different temperature regimes to the pods and the roots separately. Pods and roots were grown in different compartments that have soil temperature controlled by separate water baths. Day/night temperature regimes of 28/22 and 40/34 C with a 12-hr ‘day’ and 12-hr ‘night’ period were imposed to the pod and root compartments separately in all four possible combinations of these temperature regimes. The temperature change between the ‘day’ and ‘night’ period occured mainly within the first 2 brand the transition to tbe final temperature required up to 5 hr. After adjustment to the ‘day’ or ‘night’ temperatures, the temperatures ranged in the 40/34 C treatment between the programmed temperature and 0.6 C less (root compartments) or 0.8 C less (pod compartments); and the maximal fluctuation in the 28/22 C treatment is ± 0.3 C (root compartments) or ± 0.6 C (pod compartments).

Seed Yields

The effects of different soil temperature regimes on vegetative growth, symbiotic nitrogen fixation and seed yield of two cowpea cultivars (K 2809 and Prima) were investigated in experiments carried out in plastic houses during the UK summer. Mean maximum soil temperatures above 32°C significantly reduced vegetative growth of both cultivars, through their effects on branch, peduncle and root dry weight per plant and, to a lesser extent, leaf production. The warmest temperature regime (35.4°C) also reduced nodule activity, especially in cv. Prima. Seed yields were adversely affected, due largely to changes in the number of peduncles per plant, as mean maximum soil temperature increased from 25.8 to 35.4°C.
