Soil temperature regime (STR) is important for soil classification and land use. Generally, STR is delineated by estimating the mean annual soil temperature at a depth of 50 cm (MAST50) according to the Chinese Soil Taxonomy (CST). However, delineating the STR of China remains a challenge due to the...

In spite of the existing bans of rice straw burning, that have objective reasons (lack of technical means for mincing and plowing of straw) during the whole period of domestic production, this way of rice straw utilization remains the only possible one. However, the short-term and long-term conseque...

The yield of winter wheat is hindered by drought and low temperature in the Loess Plateau of China. Two common mulching methods to conserve soil moisture, ridge furrows with plastic film mulching (RP) and flat soil surfaces with plastic film mulching (FP) are helpful for wheat production. Our previo...

Long-term data (1964–2000) from weather stations within the territory of Irkutsk region are analyzed in the paper. Quantitative assessment was made of the soil temperature response at a depth of 1.6 m to the modern climate changes. The majority of cases showed the tendency of soil temperature to ris...

Climate changes have influence on the thermal stability of permafrost soils. The assessment of its changes should be made taking account of the parameters of the snow cover and its thermophysical characteristics. A method for determining the thermal resistance of snow cover and the effective coeffic...

Abstract The accelerated warming in the Arctic poses serious risks to freshwater ecosystems by altering streamflow and river thermal regimes. However, limited research on Arctic River water temperatures exists due to data scarcity and the absence of robust methodologies, which often focus on large,...

Numto Nature Park (Western Siberia) is one of the southernmost locations of frozen peatlands. In 2019–2022, soil temperatures were measured there using an automatic monitoring system. The measurements were carried out for Murshik Hemic Cryic Histosol on flat palsa peatlands and frost mounds. The tem...

Migratory behaviour allows individuals to inhabit areas with optimal environmental conditions throughout the year. To reduce energy expenditure and the risk of mortality while migrating, birds may schedule their departures basing on environmental cues that provide seasonal and/or local information....

The main objective of the research was to assess a nature of contingency in the seasonal course between char‑ acteristics of the soil thermal regime, surface air temperature, and snow cover, as well as to determine typical situations of their interaction. The investigation was based on results of th...

Snow cover is an important factor that largely determines the thermal regime of the ground in the cold season. Thermal protective properties of snow cover are conditioned by its thermal resistance, equal to the ratio of the snow thickness to its thermal conductivity coefficient. The thermal resistan...

Straw mulching allows for effective water storage in dryland wheat production. Finding a suitable straw mulching model that facilitates wheat growth was the objective of this study. A 2-year field experiment was conducted to investigate the effects of two straw mulching patterns (FM, full coverage w...

Soil mulching and irrigation are critical practices for alleviating water scarcity and enhancing crop yields in arid and semi-arid regions by regulating soil moisture and soil temperature. Clarifying the effects of various irrigation depths on soil moisture and temperature under mulched condition is...

Soil temperatures at different depths down the soil profile are important agro-meteorological indicators which are necessary for ecological modeling and precision agricultural activities. In this paper, using time series of soil temperature (ST) measured at different depths (0, 5, 10, 20, and 40 cm)...

Study region: The Hetao Irrigation District (Hetao), a super-large cold-arid irrigation district located in the upper Yellow River basin, China. Study focus: For cold-arid irrigation districts, understanding soil freezing-thawing processes is important for the reasonable management of non-growing se...

According to the meteorological station Barentsburg the average positive temperature of air on West Spitsbergen for the period of 1985–2011 years grows by 0,02 °C/year, and for the period of 2002–2011 it is reduced on 0,03 °C/year. The average negative temperature of air for these periods grows with...

Response of a river flow in a winter low-water period to the climate changes is analyzed by the example of theOkaRiver(245 thousand km2). The analysis was done for each individual month from December to March during the period 1980–2015. The data were obtained for the hydrometric section Oka–Gorbato...

Planting under plastic-film mulches is widely used in spring maize production in arid-cold regions for water conservation and warming the soil. To ameliorate the associated issues such as plastic-film residues and additional labor during the “seedling release” in spring maize production, we have dev...

Soil temperature plays a crucial role in ecological stability by supporting balanced processes such as nutrient cycling, and the flow of water and energy. This research aimed to analyze and predict the dynamic relationship of multi depth soil temperature (SDT) at (5 cm, 10 cm, 20 cm, and 50 cm) with...
