Energy Crop Yield Datasets applicable to BT23 modeling (POLYSYS)

Yield (i.e., tons of biomass per acre per year) is a key driver of production potential for many biomass resources. For agricultural resources, crop- and county-specific yields are an input to the economic modeling used to assess biomass production capacity in the BT23. Yields for agricultural biomass resources were derived from field trials from the Sun Grant Initiative Regional Feedstock Partnership, which served the basis for calibration of county yields (see 2016 Billion-Ton Report section 4.2.4)

A-customized-dataset-for-yield-agricultural-resources-modeled-with-POLYSYS

This dataset provides additional variables for modelers and other interested stakeholders for yield assumptions for modeled energy crops on agricultural land in the CONUS, as modeled by the POLYSYS model.

The yield unit was changed from lb/ac to dt/ac post-processing.
V0.1 changes include: tillage for subclass like 'energy crop' is now '[null]' and for subclass = 'Intermediate oilseeds' 'till' is now 'CT' (Conventional Tillage), format now uses pipe (|) delimiter.

Crop residues of the contiguous United States: Balancing feedstock and soil needs with conservation tillage, cover crops, and biochar

Crop residues are among the cellulosic feedstocks expected to provide renewable energy. The
availability of crop species and residue availability varies across the United States. Estimates of
harvestable residues must consider all the residues produced during the entire rotation. Inclusion
of fallow or low residue producing crops requires that less feedstock be harvested. A re-occurring
theme among the regions is that soils need to be safeguarded against erosion and against loss of soil
