Characteristics of successful ley pasture plants are discussed. The most important characteristics is the ability to contribute nitrogen to subsequent crops, which has been demonstrated for a number of legumes but not for grasses. Over 2300 legumes and grass introductions have been evaluated as permanent pastures. Field experiments and commercial practice have shown that Centrosema pascuorum is well adapted for use as a ley pasture plant. The grasses are generally not suitable for ley pastures as they are strong perennials which are difficult to control in cropping areas.
