Perennial ryegrass is a highly efficient builder of soil organic matter, due to its belowground productivity. It is a valuable forage and soil stabilization plant.
Perennial ryegrass establishes easier and more quickly than most of long-lived pasture grass varieties. Under ideal conditions, perennial ryegrass is ready to graze within 60 days of planting.
Perennial ryegrass can also be inter-seeded in existing weak stands of grass with fairly good results. Perennial ryegrass has a wide range of adaptability to soils but thrives best on dark rich soils. It will withstand wet soils with reasonably good surface drainage. It will not tolerate standing water for extended periods of time.
