Brief description

N2O emissions were measured in plots planted with sorghum (Sorghum bicolor L.) following two distinct cropping histories. One crop rotation (hereafter called legume ley pasture-cereal) included two seasons of alfalfa pasture (Medicago sativa, L., summers 2009/2010 and 2010/2011), one season of maize (Zea mays, L., summer 2011/2012) and one season of sulla pasture (Hedysarum coronarium L., winter 2012) prior to sowing sorghum. The other crop rotation (hereafter called grass ley pasture-cereal) consisted of two seasons of a mixed rhodes grass (Chloris gayana, K.) and alfalfa pasture (summers 2009/2010 and 2010/2011), one season of maize (Zea mays, L., summer 2011/2012) and one season of wheat (Triticum aestivum L., winter 2012). Both crops were terminated in November 2012 with all residues returned to the soil as a mulch before being incorporated into the soil with four shallow cultivations.
Two N fertilisation rates were tested on each cropping history, resulting in a total of four treatments.
