Options after Maize Optimization of ground for production of extra forage, whilst retaining nutrients, boosting soil organic matter and reducing soil erosion over winter. • Follow maize with a winter cereal • Forage rye ◊ Very hardy, capable of withstanding severe frost ◊ Ideal for grazing or conservation • IRG ◊ Quick to establish ◊ High yields for grazing or conservation • Westerwolds ◊ Similar characteristics to IRG ◊ Good at reducing nitrogen leaching over winter • Cover crop (EFA sown by Oct 1st) ◊ Choices can be limited by cooler soil temperatures ◊ Winter hardy species should be chosen • Stubble turnips/forage rape ◊ Latest sowing up to mid-September • Possibility of under sowing… Under sowing: • Under sow at 4-5 leaf stage • Depends on time of drilling: early sown crops will need a less competitive species e.g. Fescues. Later sown crops will need a species that will establish rapidly e.g. IRG • Sow at a rate of 15-19kg /ha • Drill rather than broadcast to increase success of establishment • Financial and non-financial benefits, including nutrient savings and extra forage
