abstract = {The inclusion of perennial, woody crops in land surface
models (LSMs) is crucial for addressing their role in carbon
(C) sequestration, food production, and water requirements
under climate change. To help quantify the biogeochemical
and biogeophysical processes associated with these
agroecosystems, we developed and tested a new sub-model,
CLM5-FruitTree, for deciduous fruit orchards within the
framework of the Community Land Model version 5 (CLM5). The
model development included (1) a new perennial crop
phenology description, (2) an adapted C and nitrogen
allocation scheme, considering both storage and
photosynthetic growth of annual and perennial plant organs,
(3) typical management practices associated with fruit
orchards, and (4) the parameterization of an apple plant
functional type. CLM5-FruitTree was tested using extensive
field measurements from an apple orchard in South Tyrol,
Italy. Growth and partitioning of biomass to the individual
plant components were well represented by CLM5-FruitTree,
and average yield was predicted within $2.3 \%$ of the
observed values despite low simulated inter-annual
variability compared to observations. The simulated seasonal
course of C, energy, and water fluxes was in good agreement
with the eddy covariance (EC) measurements owing to the
accurate representation of the prolonged growing season and
typical leaf area development of the orchard. We found that
gross primary production, net radiation, and latent heat
flux were highly correlated (r>0.94) with EC measurements
and showed little bias $(<±5 \%).$ Simulated respiration
components, sensible heat, and soil heat flux were less
consistent with observations. This was attributed to
simplifications in the orchard structure and to the presence
of additional management practices that are not yet
represented in CLM5-FruitTree. Finally, the results
suggested that the representation of microbial and
autotrophic respiration and energy partitioning in complex,
discontinuous canopies in CLM5 requires further attention.
The new CLM5-FruitTree sub-model improved the representation
of agricultural systems in CLM5 and can be used to study
land surface processes in fruit orchards at the local,
regional, or larger scale.},
