加拿大艾伯塔省目前约有4800个牛饲养场在运营。每年产生的大量粪便给饲养场经营者带来了处理问题。本研究旨在评价大麦长期施用一年生有机肥的效果。在阿肯色州莱斯布里奇附近的粘壤土(深棕色切尔诺兹米色，典型的Haploboroll)上生长的性能。从1973年到1989年，饲养场牛粪每年用于灌溉地块0、60、120和180毫克ha−1(湿基)和非灌溉地块0、30、60和90毫克ha−1。肥料与耕作机加圆盘、旋耕机或犁结合使用[...]
Approximately 4800 cattle feedlots currently operate in Alberta, Canada. The large amount of manure produced annually creates disposal problems for feedlot operators. The objective of the present study was to evaluate the effects of long-term annual manure application on barley (Hordeum vulgare L.) performance grown on clay loam soil (Dark Brown Chernozemic, Typic Haploboroll) near Leth-bridge, AB. Feedlot cattle manure was applied annually from 1973 to 1989 to irrigated plots at 0, 60, 120, and 180 Mg ha −1 (wet wt. basis) and to nonirrigated plots at 0, 30, 60, and 90 Mg ha −1 . Manure was incorporated with a cultivator plus disk, rototiller, or plow [...]
