Name: UNIV6020 Sample Hart Description: Working data schema for the NSERC Alliance Project (Lyons Trial) at the Ontario Beef Research Station in Elora, ON, Pasture One. Effects of pasture management strategies during the cow-calf phase of beef production, considering soil health, environmental microbiology and carbon sequestration.

Unique sample ID that corresponds to a bulk 0-15 cm soil sample. Field#-Paddock#-Transec(A/B)
treatment
Grazing management strategy
Grazing management strategies included: strip grazing, a daily rotation, rotational grazing, a 3-day rotation between paddocks, and continuous grazing (unrestricted field access).
field
Field
Corresponds to the on-farm field map. Field 1-15 inclusive. Treatment is applied at the field level (i.e. grazing strategy)
paddock
Paddock
Corresponds to the on-farm field map. 1,3,7 were selected as representative sub-samples of a field. Each paddock was one acre of an eight-acre field. Paddocks were labelled in ascending order in a U-shape from the left side of the gate.
transect
Transect
Two 50-meter transects were used to subsample a one-acre paddock. 16 cores were taken along each transect. Transect A was always positioned closest to the main road.
pmn
Potentially mineralizable nitrogen
A soil health metric quantifying the amount of organic nitrogen that can be converted by microbes to inorganic forms.
resp
Microbial respiration
A soil health metric quantifying microbial mediated CO2 released (respiration).
moisture
Gravemetric moisture content
Moisture content taken within 1-2 days of sampling via mass/mass wet and oven-dry ratio.
