Winter Wheat (Triticum aestivum) typically is grown for grain and can provide most of the cover crop benefits of other cereal crops.
Winter Wheat takes up N relatively slowly in autumn but it is heavy N feeder in spring. Wheat enhances cycling of N, P and K.
As a autumn sown, wheat competes well with most weeds. Its rapid spring growth also helps supress weeds, by competing for light and surface nutrients.
Winter Wheat prefers well-drained soils and moderate fertility and a firm seedbed helps reduce winterkill. Wheat is a plentiful source of straw and root system also improves topsoil tilth.
