1. Measure and model water-driven processes in agricultural production systems to predict and enable production under constrained conditions that affect ecosystem services. 1.A. Measure sugarcane growth, yield (tons and sugar), and residue in conventional (1.8 m) and wide row (2.4 m) production systems under ambient water conditions. 1.B. Identify field properties and utilization of resources that vary between row spacing including soil carbon and soil moisture content. 2. Measure and model fluxes of water and carbon in these systems and how they are affected by management practices.
Use field experiments to study the effects of water availability on sugarcane establishment, growth, and yield, and how row spacing-induced changes to water availability and crop physiology affects carbon cycling within the soil, plant, and atmosphere continuum. Laboratory experiments will evaluate how post-harvest crop residue, the largest soil carbon input in these field systems, cycling is impacted by the effects of water, temperature, mineral nutrients, and particle size.
