AND THE COLD RUSHES INTO MAINE. Took this shot midmorning while under sunny skies the outside air temp was -8oF when we were bringing in an empty dirt hopper. Inside our underground potato storage it’s abalmy 38oF. The smoky clouds develop instantly from relatively ‘warm’ moist potato air hitting the cold outside air. No thunder or lightning, though!
Many years ago, an Aroostook potato farmer friend told me he had been taught a trick by his potato-farming-father. On the coldest day in January, build up a big fire in the wood stove in the potato house and once it’s going strong open up all the potato house doors to change the air. Out goes the high CO2 air accumulated from potato respiration since harvest. In comes the clean dry high oxygen air. Potatoes in this way store better and Seed Potatoes have more vigor in the Spring due to less stress. Caleb, Megan & Jim
