在弗吉尼亚州、南卡罗来纳州和佛罗里达州的三个间伐中期轮作（树龄 15-20 年）火炬松种植园中，比较了冬季表施后，尿素和用脲酶抑制剂 N-(正丁基) 硫代磷酸三酰胺（尿素 + NBPT）处理的尿素之间的肥料氮 (N) 损失。处理方法用 15 N 标记，并于 2016 年 1 月和 2 月应用于开放室微观世界。施用后十五天，将微观世界从田间移走，以确定每个微观世界的肥料氮损失。与尿素 + NBPT（12% 至 22%）相比，所有地点施肥后尿素的损失（24% 至 50%）都更大（p≥.05）。佛罗里达州的肥料氮损失高于南卡罗来纳州和弗吉尼亚州，尽管弗吉尼亚州尿素施肥后的氮损失仍为 25%。与尿素（床层 = 25%，床间 = 40%）和尿素 + NBPT（床层 = 12%，床间 = 23%）相比，床层上肥料氮的损失始终较低。这项研究强调了使用尿素 + NBPT 来减少冬季施肥后肥料氮损失的价值，以及在潮湿地区的间床中更大的潜在损失。
Losses of fertilizer nitrogen (N) were compared between urea and urea treated with the urease inhibitor N‐(n‐Butyl) thiophosphoric triamide (urea + NBPT) after a surface application in winter at three thinned mid‐rotation (age 15–20 years) loblolly pine plantations in Virginia, South Carolina, and Florida. Treatments were labeled with15N and applied to open chamber microcosms in January and February 2016. Fifteen days after application, microcosms were removed from the field to determine fertilizer N lost from each microcosm. Losses following fertilization with urea (24% to 50%) were greater (p≥ .05) at all sites compared to urea + NBPT (12% to 22%). Fertilizer N losses were greater in Florida than in SC and Virginia although N loss following urea fertilization was still 25% in Virginia. The loss of fertilizer N was consistently lower on beds compared to interbeds for both urea (bed = 25%, interbed = 40%) and urea + NBPT (bed = 12%, interbed = 23%). This research highlights the value of using urea + NBPT to reduce fertilizer N losses after a winter application and the greater potential loss in the interbed on wetter sites.
