Effects of treading perennial ryegrass (Lolium perenneL.) and White Clover (Trifolium repensL.) Pastures in winter and summer at two soil moisture levels

摘要

Two uniform perennial ryegrass (Lolium perenneL.) and white clover (Trifolium repensL.) pastures, growing in a silt loam, were used (winter 1957 or summer 1958) to investigate the effects of periodical treading, where the soil was at 2 different soil moisture levels. Spray irrigation and mature Romney sheep were used.
