Root Biomass And Other Soil Properties Affecting The Co2 Flush From Laboratory Dried And Rewetted Soils, Audrey E. Laffely
Root Biomass And Other Soil Properties Affecting The Co2 Flush From Laboratory Dried And Rewetted Soils, Audrey E. Laffely
Electronic Theses and Dissertations
Soil that has been dried and rewetted has been observed to release a ‘burst’ or ‘flush’ of carbon dioxide (CO 2 ) upon rewetting. This CO 2 flush has been proposed as an indicator of soil health. This may be a valuable indicator of soil health, however the CO 2 flush has yet to be fully evaluated. Roots and root exudates influence the soil in a variety of ways that may impact the CO 2 flush, such as increasing aggregation, organic carbon (C), and microbial biomass. We conducted both field and greenhouse experiments to elucidate the relationship of root biomass …

Tb32: Evaluation Of Soil Sites For White Pine In Maine, Kenneth G. Stratton, Roland A. Struchtemeyer
Technical Bulletins
To understand environmental combinations required to produce high-quality white pine, studies of both the species and its sites have been undertaken. Increased demands on land use have also stimulated the search for species and varieties of trees that will best adapt themselves to the relatively permanent factors of the site. The purpose of this study, as undertaken originally in 1962, was to add to the basic knowledge of soil factors controlling tree growth and specifically, provide information for evaluation of soil-site quality or white pine. This investigation was designed to consider a wide range of stands, sites, and soil characteristics.
