Getting the most out of nitrogen and irrigation in a tight year

As crops approach mid tillering, it is time to start considering crop nitrogen requirements for topdressing. Many winter cereal crops this year will be grown on rice stubble, so there will be little nitrogen available without topdressing. Yet in a year with minimal water availability and a dry seasonal outlook, your nitrogen topdressing requirement should be determined by how much water you have available to finish off your crop, current soil moisture status and likely returns.
