摘要：

Sphagnum peat moss, floating on swine manure in storage, was tested during three summers as an N conservation method in experimental tanks which measured 0.75 m in diameter and 3.0 m deep. Three depths of floating pest moss (0, 10, and 20 cm) were tested. The swine manure was analyzed prior to the tests and after 14 wk of storage, from June to mid-September. An average of 54, 60, and 76% total N conservation was observed for the respective treatments. Twenty centimeters of peat moss significantly reduced manure N losses and manure evaporation during storage.
