资源简介：
Soil loss on ignition (LOI), as a proxy for total soil organic matter,
is an important control on surface hydrology. To measure soil LOI
across the Niwot Ridge LTER Saddle Stream Catchment, surface (0 – 10
cm) soil samples (n = 84) were collected on roughly a 60 x 60 m grid,
including sensor network sites. After drying, sieving to < 2mm, and
grinding to a fine powder, a ~20 g subsample of soil was combusted at
550°C for 4 hours. LOI is reported as a percent difference between dry
weights at 550°C and 105°C. The average LOI was 19.23%, but soils had
a wide range from 4.80% to 46.77%. This dataset is useful for studies
of spatial patterns in organic matter accumulation, biogeochemical
process rates, and surface hydrology.
