Now is the time to implement frost strategies.. Grain growers can best minimise crop losses from spring frosts by planning and implementing strategies prior to or at seeding time... "High stubble loads (greater than 2.5 tonnes per hectare) appear to increase frost damage by reducing the amount of heat radiated from the soil at night, leading to lower canopy temperatures and greater frost severity, duration and damage," he said...
