Assessment of future climate change impacts on water-heat-salt migration in unsaturated frozen soil using

Hanli Wan, Jianmin Bian, Han Zhang, Yihan Li

Frontiers of Environmental Science & Engineering 2021, Volume 15, Issue 1, doi: 10.1007/s11783-020-1302-5

Abstract: Abstract • A model coupling water-heat-salt of unsaturated frozen soil was established. • Future temperature, precipitation, and evaporation increase in freeze–thaw period. • Soil water, heat, and salt transportclosely coupled during freeze–thaw period. • Freeze–thaw cycles and future climate change can exacerbate salinizationThe transport mechanisms of water, heat, and salt in unsaturated frozen soil, as well as its responseEffective measures should be taken to prevent the salinization of unsaturated frozen soils and address

Some Issues on Water-saving and High-efficiency Farming of China

Sun Xuetao

Strategic Study of CAE 2002, Volume 4, Issue 9,   Pages 24-30

Abstract:

Would the foods of China be sufficient to support the need of 1.6 billion people? The answer to this question depends on the possibility of relying on the existing 400 billion m3 of irrigation water to increase grain output from the 500 million tons to 700 million tons in the future while meeting the water demand of other crops. In order to achieve the strategic goal, water-saving and high-efficiency farming must be built without any doubt. However, for a long time, emphasis was laid on the engineering works of irrigation projects while slighting their management, on the construction of main projects while slighting the timely completion of related supplementary works, on the irrigation while slighting drainage on the farms. By analyzing the current irrigated farming, the author draws a conclusion that all these problems remained unsolved are because of shortcomings in the management system, investment mechanism and price policy, and gives some reforming suggestions in the paper. It is also analyzed that great effort should be paid on the improvement of the traditional farming to pave the way for restructuring agriculture of China.

Mitigation strategies for soil acidification based on optimal nitrogen management REVIEW

Frontiers of Agricultural Science and Engineering 2024, Volume 11, Issue 2,   Pages 229-242 doi: 10.15302/J-FASE-2024562

Abstract:

Soil acidification is a serious constraint to food production worldwide.In addition, low soil acid buffering capacity, mainly determined by soil parent materials and soil organicThis study proposes targeted mitigation strategies for different stages of soil acidification, whichinclude monitoring soil carbonate content and pH of soils with pH > 6.5 (e.g., calcareous soil), use–crop management system that balances acid production and soil buffering capacity.

Assessment of glass fiber-reinforced polyester pipe powder in soil improvement

Frontiers of Structural and Civil Engineering 2021, Volume 15, Issue 3,   Pages 742-753 doi: 10.1007/s11709-021-0732-x

Abstract: Then, using the optimum PP addition, the bearing capacity of the soil was estimated through a seriesThe bearing capacity of sandy soil was improved by up to 30.7%.The ratio of the depth of the PP-reinforced soil to the diameter of the foundation model (H/D) of 1.25 could sufficiently strengthen sandy soil when the optimum PP ratio was used.capacity can be attributed to the chopped fibers in the PP and their multiaxial distribution in the soil

Frontiers of Structural and Civil Engineering 2007, Volume 1, Issue 2,   Pages 198-204 doi: 10.1007/s11709-007-0023-1

Abstract: The intensive soil-water interaction in unsaturated expansive soil is one of the major reasons for slopeIn this paper, the soil-water interaction is investigated with the full-scale field inspection of rainwaterIt is demonstrated that the soil-water interaction induced by seasonal wetting-drying cycles is veryIn addition, the abundant cracks in the expansive soil play an important role in the soil-water interactionThe seasonal wetting-drying cycles tend to result in a down-slope creeping of the shallow soil layer,
