Pasture cropping‐integrating livestock and crop production for sustainable management of rangelands in south east Australia
Pasture cropping (PC) is an intercropping technique that was developed by farmers in the Central West region of New South Wales, Australia to retain perennial grasses for summer/autumn grazing.Winter cereal crops are sown directly into summer growing (C4) native pastures (e.g.Bothriochloa macra and Paspalidium j ubi f lorum) to exploit their complementary growth phases.The experiment examined the production and environmental differences between grazing pasture (PA), PC and no till (NT) wheat cropping.PC yields were significantly lower than NT and were limited by nitrogen.There was only a minimal reduction in the density and basal area of perennial grasses from PC compared to PA.Gross margin increased from PA to PC to NT, but higher returns were associated with higher annual volatility.
