For grains, the agricultural grain harvester is fitted with a GPS-referenced yield monitoring system to provide yield maps for each 1 ha treatment plot. Additionally, grain is off-loaded into weigh wagons and weighed at the KBS dairy . Alfalfa and wheat straw is measured on a gravimetric basis per plot after it has been cut and baled. Gravimetric moisture content is measured and subtracted from the biomass and the harvestable biomass estimate presented as dry weight alfalfa or straw per area.Data Managerhttp://lter.kbs.msu.edu/protocols/29Agronomic yields are defined as the crop grain and non-grain biomass harvested in a given growing cycle and serve as the basic measurement for comparing production differences among treatments. For annual row-cropping systems of corn, soybean and wheat, yield is determined as the grain biomass collected during harvest; for annual sorghum, yield is determined as the non-grain biomass harvested. For perennial crops, including monoculture systems, such as switchgrass and miscanthus, and polyculture systems that are harvested annually, such as restored prairie, native grasses,and early successional (GLBRC only), yield is determined as the biomass harvested at the end of the growing season. For alfalfa, harvested several times per year, yield is the sum of biomass harvested over the growing season. For woody cropping systems of short-rotation poplar, annual yield is determined as the biomass collected at clear-cutting divided by the number of years of growth. Crops are harvested using commercial sized equipment; for the specific harvesters and equipment used see the Agronomic Activity Report (KBS004-012) or search the Ag-log at https://aglog.kbs.msu.edu/ for Harvest under the Observations tab.
