Managing Global Resources for a Secure Future

Skip to search form Skip to main content. Myrold and Peter J. Bottomley Published A disturbance gradient was created to evaluate the relationship between changes in soil physical and chemical properties with microbial community composition. Plots of a yr fallow Ultisol in Northeastern Brazil were arranged in a Latin Square design and disturbed by tillage events applied zero, one, two, three, or four times over a 3-mo period. Sixty days aft er the last event, plots were sampled 0—20 cm and soil analyses performed. View PDF.

The uncertainty associated with how projected climate change will affect global C cycling could have a large impact on predictions of soil C stocks. The purpose of our study was to determine how various soil decomposition and chemistry characteristics relate to soil organic matter SOM temperature sensitivity.

The Soil Biology and Biochemistry Division brings together scientific experts in the fields of soil biodiversity, soil biological organisms, biochemical properties of soil organic matter, biogeochemical processes of the elements, and below-ground plant microbe interactions. Pooling the resources of these scientists, the Division addresses scientific questions in these fields, promoting the acquisition and dissemination of scientific knowledge of soil biology and biochemistry for the understanding, conservation, and restoration of our soil resources for agriculture and food production, and urban and rural environmental quality. Clark Distinguished Lectureship on Soil Biology. This lectureship honors Francis Clark's life-long commitment to the greater understanding of soil, plant, and microbial interactions and of nutrient cycling in terrestrial ecosystems. The lectureship focuses on topics in soil biology that are of interest to teachers, researchers, and students. The lecture emphasizes new frontiers in all aspects of soil biology and the importance of soil biology in addressing agricultural, environmental, and socio-economic issues.

The preparation of soil for measurement of properties such as microbial biomass P involves the removal of plant roots. Any soil attached to the roots root-attached soil is also removed. In a very poorly drained silty clay loam under grassland we found that the root-attached soil contained more than twice the quantity of bicarbonate extractable P than the bulk soil. Discarding this root-attached soil could potentially result in underestimation of bicarbonate extractable P. We also showed that preferential inclusion of deeper soil due to variability of root density with depth is likely to result in underestimation of soil bicarbonate extractable P in fumigated and unfumigated soil samples. Additionally we investigated a conventional and alternative rapid soil preparation technique that might affect the accuracy of measurement of soil bicarbonate extractable P as part of a microbial biomass P measurement. Preparation technique made no significant difference to the quantity of P recovered.
