Bentonite buffers at temperatures beyond 100 °C could reduce the amount of high-level radioactive waste in a deep geological repository. However, it is necessary to demonstrate that buffer surrounding canisters withstands such elevated temperatures, while maintaining its safety functions (regarding long-term performance). For this reason, an experiment with thermal loading bentonite powder 150 ...

Improving soil fertility and crop productivity is crucial to reduce food insecurity poverty in Nepal. Biochar as a amendment has been found effective increasing production. Here, we reviewed various biochar studies carried out Nepal by different organizations assessed future potential of an amendment. In this review, have included the pretreated (enriched) with nutrient or added separately soil...

Zeolites have been used in agriculture since the 1960s, due to effectiveness of these crystalline microporous solids as soil amendments for plant growth, their cation exchange capacity (CEC) and slow-release fertilizer properties. Most work on fertilizers has focused natural Clinoptilolite, Phillipsite Chabazite. The aim this study was synthesize clinoptilolite type zeolite-enriched amendments....

Soil structure is an important key in the bioremediation process; for instance, clay soils tend to have high absorption of pollutants and low rates due their plasticity oxygen restrictions. This work assesses seven different treatments contaminated soil using lime, silica nanoparticles, both components combination. After a three-month treatment, variation granulometry, pH, porosity, cation exch...

Biochar (BC) has attracted attention due to its impacts on soil quality by enhancing fertility, carbon storage and contaminants immobilization. BC also induces changes in microbial community structure enhances crop productivity long term scenarios compared many other organic amendments. However, information related the role of modified BCs altering is still scarce. can be using physical, chemic...

A number of environmental, agronomic and engineering applications require knowledge the Atterberg limits (liquid limit, LL; plastic PL) plasticity index, PI soils. The tedious costly nature standard experimental methods, as well challenges with measurement repeatability motivated development regressions more sophisticated techniques to estimate from other properties such clay content, cation ex...

Abstract Background and aim The use of amendments to immobilize metals in polluted soils is a widely accepted remediation approach, the framework circular economy, produced from mining and/or biomass waste have gained relevance. However, application such can also mobilize metalloids. Here we propose combination nanoscale zero-valent iron nanoparticles (nZVI) with dunite (mining waste) compost f...

ABSTRACT The rational use of water while considering the increases in food production is a great challenge for agriculture currently. aim present study was to evaluate soil properties rice paddy areas under different management systems. For this, cultivars BRS Tropical and IRGA 424 were grown following treatments: M1: Intermittent flooding; M2: flooding, followed by continuous M3: Continuous in...

Abstract The study aimed to investigate the temporal changes of pH, sorption complex, and structure soil organic matter through forest profile under beech spruce forests located in Jizera mountains (Czech Republic) affected by natural anthropogenic acidification. Soil samples were collected four different years (2008, 2013, 2015, 2020) each horizon: fermented horizons (F), humified (H), organo-...

This research evaluated the effect of biochar amendment rate on nitrogen species and organic carbon removals hydraulic performance in biofilter columns treating dairy farm runoff. Initial studies compared sand amended with two types different specific surface area (SA) cation exchange capacity (CEC) an un-amended column. The results showed that enhanced N-species removal due to its unique physi...
