Linking soil biology and chemistry in biological soil crust using isolate exometabolomics

Impact of Environmental Factors and Biological Soil Crust Types on Soil Respiration in a Desert Ecosystem

The responses of soil respiration to environmental conditions have been studied extensively in various ecosystems. However, little is known about the impacts of temperature and moisture on soils respiration under biological soil crusts. In this study, CO2 efflux from biologically-crusted soils was measured continuously with an automated chamber system in Ningxia, northwest China, from June to O...

Soil Chemistry

Sludge of two different ages (3 years old; Type 1 sludge, and 3 months old; Type 2 sludge) were applied to the following soil types: two luvisols, an arenosol and a vertisol at different rates to determine whether sludge application had any effect on the partitioning and consequently, bioavailability andmobility of Cu, Pb and Zn. A fivestage sequential extraction procedurewas used to determine ...

Milestones in Soil Chemistry

An array of pioneering research, dealing with various aspects of soil chemistry, has appeared in Soil Science for the past 90 years. In this review, two papers that have shaped the field forever are featured and discussed. The paper by Mattson (1931) and the many others that he published in Soil Science established the importance of variable or pHdependent surface charge on colloids and soils a...
