Clearing the Air: How Fine Particulate Matter Regulations Reshape Farmland Values in U.S. Corn and Soybean Regions

Journal of Agricultural Economics, EarlyView.
ABSTRACT We investigate the impact of air quality regulations targeting fine particulate matter (PM2.5) on farmland values in corn and soybean producing counties in the United States over the period 1997–2022. Using self‐reported farmland value data from the Agricultural Census and county‐level pollution classifications provided by the Environmental ...

Weighing the options: a test of alternative stomatal optimisation models at high temperatures

New Phytologist, EarlyView.
Summary Stomatal optimisation models centre upon a fundamental tradeoff for plants: opening stomata promotes carbon uptake, but closing stomata prevents water loss. However, stomatal opening can occur at high temperatures, causing evaporative cooling which limits thermal damage to leaves.

Evapotranspiração de referência com base na radiação solar global estimada pelo método de Bristow-Campbell Reference evapotranspiration based on solar radiation estimated by the Bristow-Campbell model

Engenharia Agrícola, 2010
A quantidade de água a ser aplicada em sistemas de irrigação é normalmente calculada com base na evapotranspiração de referência (ETo) da região. Vários métodos podem ser empregados para o cálculo de ETo, sendo o de Hargreaves um dos mais adotados.
