TL;DR: In this paper, the authors evaluated the applicability and efficacy of GPFARM based on simulation model performance for dry mass grain yield, total soil profile water content, crop residue, and residual NO3-N across a range of dryland no-till experimental sites in eastern Colorado.

TL;DR: In this paper, the authors describe the standalone Unified Plant Growth Model (UPGM), initially derived from the WEPS plant growth model, to be used for merging enhancements from other EPIC-based plant growth models; and describe and evaluate new phenology, seedling emergence, and canopy height sub-models derived from Phenology Modular Modeling System (PhenologyMMS V1.2) and incorporated into UPGM.

TL;DR: The effect of drought on the persistence of SOC was examined to determine soil C pools after 24 yr in no-till as influenced by potential evapotranspiration (PET), landscape position (slope), and CI; and to compare the size of the C pool after the first 12 yr (wet) versus the subsequent 12 yr, notable for frequent droughts.

TL;DR: In this article, the structural Composite Design Pattern (CDP) was used to simulate the appearance, growth, and death of phytomer units in a crop model. But, the authors did not consider the interplay of repeating phytomers, which is analogous to the repeating melodies of a canon musical composition.

TL;DR: In this article, a new method for measuring canopy water interception from plant shoots is described, and a lightweight, movable framework was placed around a balance, and buckets containing corn plants were placed on the scale one container at a time.
