Evaluating soil storage impacts on aminopeptidase activity can inform the use of aminopeptidase activity in soil N cycling assessments. We evaluated the impact of soil refrigeration (4 °C) and air-drying relative to field-fresh (4 °C for ≤ 3 d) on the activities and sensitivity of eight amino acid-specific aminopeptidase activities across a 42 y N fertilization gradient (0–269 kg N ha − 1 ) over 1.5, 6, 12 and 24 mo storage.

Growing dedicated bioenergy crops on marginal land can provide beneficial outcomes including biomass production and energy, resource management, and ecosystem services. We investigated the effects of harvest timing (peak standing crop [PEAK] or after killing frost [KF]) and nitrogen (N) fertilizer rates (0, 56, and 112 kg N ha −1 ) on yield, nutrient concentrations, and nutrient removal rates of perennial grasses on a wet marg...
