At the same time, researchers will collect and weigh leaf litter and measure soil carbon content at various depths to learn how increased atmospheric carbon dioxide is affecting the carbon cycle in rainforests.
Soil is a critical component of global biogeochemical cycles, and there is an increasing need for cost effective tools to measure soil carbon stocks and determine soil nitrogen contents.
Measured soil carbon has been found to decrease following afforestation of grasslands with P. radiata (Parfitt and Ross [2011]) but increases over time as pine litter accumulates, resulting in a higher soil total C content (Davis and Condron [2002]; Paul et al. [2002]; Laganiére et al. [2010]).
Measuring soil organic carbon (SOC) mineralization in macro-aggregates (250 2000 μm), micro-aggregates (250 53 μm) and the < 53 μm fraction helps to understand how spatial separation of SOC inside soil aggregates regulates its dynamics.
We measured soil organic carbon (C) sequestration and nutrient (nitrogen-N, phosphorus- P) burial in Czech and Midwest U.S. freshwater floodplain and depressional wetlands to evaluate how landscape position and agricultural land use intensity affects C, N, and P retention.
We measured soil organic carbon stocks and a suite of edaphic factors in the upper 10 cm of a series of restored tallgrass prairies representing a range of drainage conditions.
The majority of chemometric modelling studies have focused on measuring only total soil carbon (C), with only a few evaluating individual soil C pools.
With the difficulty in measuring things like soil carbon sequestration, will these credits be real?
Now while McCain's imaginary questioner notes "the difficulty in measuring things like soil carbon sequestration," the conservative nominee seems unaware that soil science has completely passed him by.
