Coordinating agronomist: Lana Shaw
Organization: South East Research Farm Inc.
Practices: Cover crops, nitrogen management
Barrier: There is concern about the economic risk of reducing nitrogen fertilizer rates in cereals with under-sown clover.
Description: This trial evaluates reduced nitrogen rates (70% of standard) combined with under-sown clover (red clover) in a rain-fed oat production system. It will assess impacts on nitrogen use efficiency, cereal yield and quality, nitrogen credits from the red clover to the subsequent crop, and the profitability of intercropping, providing practical evidence for adopting these integrated practices.
