“…Indeed, effective inhibition of NH-N incorporation in amino acids was found to increase the N mineralization of cytoplasmic protein-N (Reitzer and Magasanik, 1987). Both net N mineralization and CO2 evolution were increased from an organic sandy soil amended with MSX, or L-methionine or methionine sulphoxide another methionine analogue (Hopkins et al, 1995). These increases were attributed to the mineralization of the added compounds by soil microflora.…”

Summary-Short-term (up to 48 h) incubation assays were conducted in the presence of L-methionine-DL-sulphoximine (MSX), an inhibitor of glutamine synthetase, to assess its effect on exchangeable NH: -N, NOT-N production, and CO2 evolution. A sandy-clay-loam (Pistoia) and a sandy (Romola) soil were moistened and either amended with glucose (200 pmol glucose-c g-I soil), glucose + (NH&SO., [50 ymol N g -' soil as (NH&SO41 or left unamended. In the two unamended soils, NH:-N concentration was increased by the highest MSX level (1 pmol g-I soil), while the lowest inhibitor concentration (0.5 pmol g-' soil) had less influence. NH:-N concentrations were higher with I pmol MSX than without the inhibitor in the glucose-only-treated Pistoia soil in the (r12 h period; thereafter the opposite situation was observed. Probably the CO2 evolution increased as a result of inhibitor mineralization after 12 h. In the glucose-treated Romola soil both MSX concentrations were generally effective in increasing NH:-N concentrations with respect to the same amendment without the inhibitor. These increases were probably due to glutamine synthetase inhibition by MSX and not to the presence of mineralization of the inhibitor because CO2 evolution was only slightly increased at 48 h by MSX. Probably, as a result of this inhibition, Nor-N was used as an alternative N source in the glucose-amended Romola soil. The inhibitor had no significant effect on NH:-N concentration when both soils were amended with glucose + (NH&SO4 probably because, in the presence of high NH:-N concentrations, NH, assimilation occurred more through glutamate dehydrogenase than through glutamine synthetase-glutamate synthase enzymes. NOT-N concentrations were decreased by MSX in the glucose-amended Romola but not in the glucose-amended Pistoia soil.

Due to urban sprawl, the demand for land has increased for the purpose of construction. It is unlikely that soil available at different construction sites will be suitable for designed structures. For improving the load-bearing capacity of the soil, different soil binders are used, which are present in distinct states. In this review, the authors have collected details about various binders, which are generally used in the soil stabilization, and their effect as a binding agent on the soil. In this article, the authors tried to review different traditional binders. After studying various research articles, the authors found that lime, ground-granulated blast slag (GGBS) polypropylene, polyurethane grouting, and asphalt mix are frequently used binders. However, the authors also gathered information about the negative environmental impact of these traditional soil binders, which led to the need for alternatives to these commonly used soil binders. To diminish this issue, different alternate hydraulic and non-hydraulic binders are discussed. The authors found alternatives to cement and lime with the alkali-activated material consisting of Na2O and silica modulus and belite-calcium sulfoaluminate ferrite, which is also known as “Aether™.” According to the research, both alternatives emit 20–30% less CO2 into the environment and also improve the compressive strength of the soil. The various studies promotes bitumen modification. Incorporating 20-mesh crumb rubber and bio-oil into the bitumen reduces its viscosity and improves its fatigue value. When waste oil is mixed with asphalt, it revitalizes the bitumen, improves fatigue resistance, and increases compressive strength. The soil particles treated by Eko soil are held together by enzymes, which give them the same strength as cement. Apart from that, low-carbon binders such as basic oxygen furnace slag, bamboo fiber, enzyme-based soil treatment, zebu manure for stabilization, and lignin-contained biofuels and coproducts are discussed. Replacing these traditional binders helps with energy savings. All waste products are recycled, and energy is saved by not manufacturing traditional binders. Additionally, energy is saved, which is required to avoid the detrimental effects of these conventional binders, making them energy-efficient alternate binders. The authors also summarize the methods used, impacts, and changes that occur in soil properties after using substitutes in place of traditional binders. From the review, the authors determined that different binders have various properties in terms of chemical and physical compositions, and they show different variations in terms of strength when added to soil with low bearing capacity or poor stability.
