Description
Annual pasture legumes (mainly Medicago spp. and Trifolium spp.) are the basis of sustainable farming systems in the cereal-livestock distcicts of South Australia. However, several factors in the cropping and pasture phases deplete legume seed reserves. While total legume seed reserves measured during summer and autumn after a cropping sequence are a useful guide to legume regeneration, the readily germinable seed (i.e., soft seed) is a much beUer guide. We have developed a simple but accurate method of predicting natural regeneration of legume pastures based on the controlled watering of representative sites on stubble paddocks during the summer-autumn period as a guide to farmers who may need to sow additional legume seed.
