Dataset Abstract

This data set contains information about agronomic yields for the Main Cropping System Experiment which include treatments 1-4 (corn – wheat – soybean rotations) and after 1994 treatment 6 (alfalfa). Agronomic yields are measured during normal crop harvest; yields are determined by machine harvesters appropriate to each crop as described in the Agronomic protocol.

Data Entities
Data Table Name:
Kellogg Biological Station LTER: Agronomic Yields - Annual Crops (KBS020-001)
Description:
Annual crop harvest data for corn, soy and wheat from the Main Cropping System Experiment at the LTER Main Site as collected with commercial sized equipment. Prior to 2017 the yield was reported from the east half of the plot. In 2017 the protocol was changed to report the yield for the whole plot.
Data Table Name:
Kellogg Biological Station LTER: Agronomic Yields - Alfalfa (KBS020-003)
Description:
Yields from the alfalfa (treatment 6) harvests of the Main Cropping System Experiment at the LTER Main Site.
Data Table Name:
Kellogg Biological Station LTER: Agronomic Yields - Weed and Fertilizer Microplots (KBS020-004)
Description:
Annual crop harvest data of corn, soy and wheat in Weed and Fertilized Microplots in Treatments 3 and 4 of the Main Cropping System Experiment at the LTER Main Site. Microplots were established to determine the effect of normal weed control and fertilization practices and the response to removing weed and nutrient limitations from the plots.
Data Table Name:
Kellogg Biological Station LTER: Agronomic Yields -- Wheat Straw (KBS020-005)
Description:
Wheat straw is harvested and baled and weighed in the years when wheat is grown on the site. The whole plot is baled as one instead of being split into east and west sections as is done for the grain harvest.

Methods and protocols used in the collection of this data package
Description:
Agronomic 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, early successional (GLBRC only) and historical vegetation (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":https://aglog.kbs.msu.edu/ at https://aglog.kbs.msu.edu/ for Harvest under the Observations tab.
Protocol:
Title: Agronomic Yields
Url:http://lter.kbs.msu.edu/protocols/194
Description:
Sampling Frequency: minimum of once per year Harvestable biomass in each cropped plot is measured at the time of crop harvest. 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.
