Geotechnical engineers face a great deal of difficulty while developing a structure’s foundation weak soil layers. As a result, scientists turn to adding chemical or pozzolanic additives to weak sandy soil in order to improve its characteristics. The purpose of this study is to evaluate the impact of adding metakaolin as pozzolanic materials to loo...

Weak soil characteristics pose a significant challenge for geotechnical engineers when designing the foundations of a structure. Consequently, researchers resort to improving the properties of weak sandy soil by mixing it with pozzolanic or chemical additives. This study aims to assess the effects of using cementitious materials to enhance the stre...

Introduction: The sandy soils in the arid Southern Balkhash region have experienced anthropogenic degradation, leading to the formation of bare mobile sand dunes. This transformation has created significant challenges for the growth of cattle feed, particularly in areas with high economic activity. As a consequence, the socio-economic situation of ...

The main purpose of this study is to substantiate the relationship between the coefficient of vibrocreep and the frequency of dynamic vibration exposure based on laboratory dynamic triaxial tests using sandy soil as an example. These studies were carried out as part of the design of new metro stations and tunnels in the city of Moscow. As a result ...

The effect of clay and humic materials in the control of nitrate leaching from sandy soil was established through a column experiment. In a PVC column with 3 inches dia and 45 cm length packed with sandy soil, six leaching at 15 days intervals were performed. Nitrogen was added @ 150 kg ha-1. The results of the study indicated the significant influ...
Controlled drainage with subirrigation (CD-SI) could be a viable measure to i) retain, ii) recharge, and iii) discharge recharge fresh water in agricultural fields. Four field CD-SI pilots with varying geohydrological conditions in the sandy Pleistocene uplands in the Netherlands were monitored (minimum 5 years) to study the effects on groundwater ...

The aim of the research was to identify the influence of environmental factors inherent in the alluvial and displaced sands of the study region on the growth of the Jack pine and the prospects for its cultivation. We found that the success of growth of Jack pine seedlings on sandy soils depends on a set of factors, which include the presence or abs...
Shrimp waste is rich in organic compounds and essential plant nutrients, e.g., calcium (Ca), and converting these wastes to organic fertilizer is important for environmental preservation and to achieve sustainable agricultural management. In the current study, Ca-rich biochar was prepared from shrimp wastes (SWB) by pyrolysis at 300 °C. We hypothes...
We developed an empirical soil wetting geometry model for silty clay loam and coarse sand soils under a semi-permeable porous wall line source Moistube Irrigation (MTI) lateral irrigation. The model was developed to simulate vertical and lateral soil water movement using the Buckingham pi (p) theorem. This study was premised on a hypothesis that so...
