Ammonia suppressants are applied to chicken litter to decrease ammonia levels. And mushroom (Agaricus bisporus) producers use poultry litter to increase the nitrogen in the compost. To determine the influence of ammonia suppressants used in poultry litter on compost preparation and mushroom production, four mushroom crops were cultivated from compost prepared using litter treated with PLT, Barn Fresh and Impact-P at 25.22 kg/100 m2, 40 kg/100 m2, and 0.49 kg/100 m2, respectively, during the poultry production process. In general, no significant differences (P>0.05) were noted between treatments for total nitrogen, ammonia, pH, EC, ash, and moisture when compost or the headspace air was sampled during compost preparation throughout all stages. Nor were mushroom yields or counts significantly affected (P>0.05) by the presence of ammonia suppressants in the poultry litter. Thus, the mushroom industry can confidently use poultry litter amended with PLT, Impact-P, and Barn Fresh when used at the recommended rates.
氨抑制剂被应用于鸡舍垫料以降低氨气水平。而蘑菇（双孢蘑菇）生产者使用家禽粪便来增加堆肥中的氮含量。为了确定家禽垫料中使用的氨抑制剂对堆肥制备和蘑菇生产的影响，在四个蘑菇种植季中，使用分别以25.22千克/100平方米、40千克/100平方米和0.49千克/100平方米的用量在禽类生产过程中用PLT、Barn Fresh和Impact-P处理过的垫料制备的堆肥来种植蘑菇。总体而言，在堆肥制备的所有阶段对堆肥或顶空空气进行采样时，各处理之间在总氮、氨、pH值、电导率、灰分和水分方面均未观察到显著差异（P>0.05）。家禽垫料中氨抑制剂的存在对蘑菇产量或数量也没有显著影响（P>0.05）。因此，蘑菇产业可以放心地使用按推荐用量添加了PLT、Impact-P和Barn Fresh的家禽垫料。
