NEON Decommissioned Site data: Soil chemical and physical properties (Megapit) from D04 MAME site

Soil chemical (and physical) properties (Megapit): Soil chemical and physical properties are measured by horizon from a single temporary soil pit at each terrestrial site at depths of up to 200 cm at non-permafrost sites (up to 300 cm at Alaskan sites). Soil properties affect the movement of soil water and nutrients through the soil profile and their availability to plants and soil organisms. In addition, these properties relate to the storage and accessibility of nutrients in the soil and influence biogeochemical cycling rates. The sampling location is expected to be representative of the NEON sensor-based soil plots and this sampling activity is expected to occur once at each NEON terrestrial site. Additional soil samples collected from the same soil pit are archived in the NEON Megapit Soil Archive and are available upon request.
