The use of biochar can contribute to carbon (C) storage in soil. Upon addition of biochar, there is a spatial reorganization of C within soil particles, but the mechanisms remain unclear. Here, we used Fourier transformed infrared-microscopy and confocal laser scanning microscopy to examine this reorganization. A silty-loam soil was amended with three different organic residues and with the bio...

The effects of four soil types, soil porosity, particle size, and organic matter were tested on survival and migration of Xiphinema americanum. Survival and migration were significantly greater in silt loam than in clay loam and silty clay soils. Nematode numbers were significantly greater in softs planted with soybeans than in fallow softs. Nematode survival was greatest at the higher of two p...

Recently, the bio-mediated soil improvement techniques have gained an increasing attention. In this method, bacteria was cultivated aerobically in laboratory and added to with reactant solutions such as urea calcium chloride. Most of existing studies are on sandy soils a few researches done silty soils. However, most nature compounds fine-grained coarse-grained soils, silt does not very good re...
