There is some good news this week for California farmers: more medium grain rice from the Sacramento Valley is headed to China. And, the federal government has okayed more funding to fight the 20 pound rodent that is a threat to Delta area farmland - the Nutria. The weather will be considerably colder in the days ahead. How cold? Will it get cold enough to damage young walnut trees in orchards? We talk with a farm advisor about precautions that walnut growers should now be considering. Also, we delve into the frontiers of agricultural science: the use of biologics on California farmland. That includes cutting edge products such as biostimulants for the soil and plant growth regulators for bigger crops. All that, crop reports, the extended weather, and more…on this week’s KSTE Farm Hour.
