Long-term tillage and residue management effect on soil compaction and nitrate leaching in a Typic Haploxerert soil

A field experiment was conducted to compare the effects of long-term tillage and cropresidue management on some physical properties and nitrate leaching of a Typic Haploxerertsoil under winter wheat (Triticum vulgare L.)-soybean (Glycine max L.) double-croppingsystem. The tillage systems consisted of conventional tillage with stubble (CT1), conventionaltillage with stubbles burned (CT2), heavy ...

Effects of long-term fertilization on soil humic acid composition and structure in Black Soil

The composition and structure of humic acid (HA) can be affected by fertilization, but the short-term effects are difficult to detect using traditional analysis methods. Using a 35-year long-term experiment in Black Soil, the molecular structure of HA was analyzed with Fourier transform infrared spectroscopy (FTIR), 13C nuclear magnetic resonance spectroscopy (NMR), and fluorescence spectroscop...

A critical review on structure-soil-structure interaction

The purpose of this paper is to review computational methods in structure-soil-structure interaction. As a result of globalization, buildings are located close to each other. This issue happens especially in big cities, making the study of structure-soil-structure interaction as an essential part of structural design process. The effect of soil medium, on which the building structure stands, es...

Soft Soil Seismic Design Spectra Including Soil-structure Interaction

Design spectrum is known as an essential tool in earthquake engineering for calculation of maximum (design) responses in a structural system. Soil-structure interaction (SSI), as a phenomenon of coupling of responses of a structure and its underlying soil, was explored after introduction of design spectra and has not been taken into account in developing a design spectrum traditionally. To cons...
