Biochar-compost as a new option for soil improvement: Application in various problem soils.

Science of the Total Environment, 2023
Due to the synergistic effects of biochar and compost/composting, the combined application of biochar and compost (biochar-compost) has been recognized as a highly promising and efficient method of soil improvement.

Production of artificial humic acid from rice straw for fertilizer production and soil improvement.

Science of the Total Environment, 2023
In this study, artificial humic acid (AHA) was produced from rice straw at room temperature. The response surface methodology was used to investigate the response of artificial humic acid to time, liquid-solid ratio, and KOH concentration.

Comparison of Soil Improvement Methods using Crude Soybean Enzyme, Bacterial Enzyme or Bacteria Induced Carbonate Precipitation

Geotechnique, 2022
Either microbial or enzyme induced carbonate precipitation (MICP or EICP) has emerged to be alternative to cement-based ground improvement methods. For EICP, either plant urease or bacterial enzyme can be used.

Bio‐mediated soil improvement: An introspection into processes, materials, characterization and applications

Soil use and management, 2021
For a long time in the practice of geotechnical engineering, soil has been viewed as an inert material, comprising only inorganic phases. However, microorganisms including bacteria, archaea and eukaryotes are ubiquitous in soil and have the capacity and ...

Multiple-phase enzyme-induced carbonate precipitation (EICP) method for soil improvement

Engineering Geology, 2021
Enzyme-induced carbonate precipitation (EICP) is a potential method to improve the mechanical properties of granular soil. The one-phase premixed percolation method using purified urease enzyme is widely adopted for in-situ EICP treatment currently, but ...

An eco-friendly versatile superabsorbent hydrogel based on sodium alginate and urea for soil improvement with a synchronous chemical loading strategy.

Carbohydrate Polymers
In this paper, an eco-friendly versatile superabsorbent material was designed for soil improvement, and a synchronous chemical loading strategy was proposed. In this strategy, urea not only acted as fertilizer but also acted as a crosslinker to construct
