Abstract
Controlled-release fertilizers (CRFs) are water-soluble pellets of homo- or heterogenous mineral nutrients covered with polymer or resin that become increasingly porous as temperature increases, releasing water-soluble fertilizer through diffusion. An experiment was carried out at the North Willamette Research and Extension Center located in Aurora, OR, USA (lat. 45°16′51″N, long. 122°45′04″W) with six fertilizer concentrations of a CRF fertilizer that was designed to last 6 to 7 months at 70 °F. During the experiment, the Pacific Northwest experienced a series of early-summer (June) heatwaves that caused an unanticipated and excessive release of mineral salts. Extreme weather adaptation strategies are necessary to sustain horticultural production in a period with increased temperature volatility.
期刊介绍：
HortScience publishes horticultural information of interest to a broad array of horticulturists. Its goals are to apprise horticultural scientists and others interested in horticulture of scientific and industry developments and of significant research, education, or extension findings or methods.
