In situ soil amendments can modify the Pb bioavailability by changing soil Pb speciation. Urban soils from three vegetable gardens containing different total Pb concentrations were used. The study evaluated how compost amendment and aging of soil-compost mixture in situ affected the following: (i) soil Pb speciation in the field and (ii) change of soil Pb speciation during an in vitro bioaccess...

Soil water content impacts all soil physical, chemical and biological properties. Soil water movement in shallow soil layers has critical importance for plant water use, foundation stability, energy transfer and chemical diffusion. Numerical analysis is one way to study soil water. New numerical methods are presented in this thesis to determine soil water content from time domain reflectometry ...

The choice of formulation is influenced by the following factors: the physical properties of the pesticide (melting point, solubility, and volatility), the chemical properties of the pesticide (hydrolytic stability, thermal stability, and irradiation stability), the mode of application of the formulation (soil, foliar), the crop to be treated and the agricultural practices, the biological prope...

By installing FBG sensors on the geogrids, smart geogrids can both reinforce and monitor the stability for geogrid-reinforced slopes. In this paper, a geogrid-reinforced sand slope model test is conducted in the laboratory and fiber Bragg grating (FBG) sensing technology is used to measure the strain distribution of the geogrid. Based on the model test, the performance of the reinforced soil sl...

In China, increasing the quantity and quality of total carbon nitrogen stocks in sandy soil used for crop production is an important research issue. Soil amendment with pelletized straw could improve both physical structure fertility soils, but these aspects remain understudied. The present pot field experiments examined dynamic changes water holding capacity, bulk density, stocks, distribution...
