Salt retention in wetland soils and effects on dissolved organic carbon export
… spots for many nutrients including carbon. The interactions between deicing salt runoff and wetland soil carbon were explored by measuring chloride export and retention, dissolved organic carbon (DOC) export, and carbon quality using mesocosm experiments. Net retention of Cl- was …

Influence of light and algae on nutrient transformations at the sediment-water interface of an agricultural stream
… water interface, and algae on dissolved organic carbon (DOC), nitrogen, and phosphorus within Maple Creek, an agriculturally impacted stream located in Fremont, Nebraska. Simultaneous continuous injection experiments into replicate open- and closed-bottom chambers were used to control the …

COMPARING LONG-TERM SOIL CARBON CONTENT AND THERMAL STABILITY AMONG DIFFERENT AGRICULTURAL SYSTEMS
Soil carbon stability is vital for maintaining the global carbon cycle balance, biodiversity conservation, and sustainable agriculture. While the earth’s climate is experiencing unprecedented changes in recent years and will be more unpredictable in the future, it is urgent to determine the factors …

Development of Soil Survey Methods for Urban Areas
… soil is the nature and properties of its organic carbon with a significant percentage of black carbon (a particulate product of incomplete combustion), which is less biologically active. Thus, in order to determine the ability of a soil to support biological activity and supply nutrients for plant …

Ecological assessments of Pseudomonas communities in pastoral soils: implications for disease suppression and sustainable production in agricultural grasslands
… ecosystem services such as ensuring water quality and soil carbon storage. An increasing proportion of grasslands are being used to support grazing livestock, with agricultural grasslands covering over 25% of the Earth’s ice-free land surface. Despite the increasing economic value of …
