Barley has relatively low water usage compared to other cover crop species, especially during earlier growth stages. Under poor fertility conditions, barley would be a good choice and can help render P & K available for your next crop. Barley provides a good feed quality grain that can be harvested 2-3 weeks earlier than wheat which then allows your double crop/cover to be planted sooner.
