Covering leek during frosty periods can reduce frost damage, saving the quality of the produce. But what kind of crop covering gets the best results? Air temperatures of -15°C and a ground temperature of -12,6°C requires the land to be covered. Leek in particular, says Belgian research company Inagro, won’t sustain such temperatures without some form of shielding.
The type of cover, obviously, has an impact on the quality and temperature of crops. Average frost was reduced by 2 ° C more under a double crop cover (both Double Fleece and Fleece + perforated foil) than under a single cover (howicover, Fleece, perforated foil). When removing the cover, there was a difference in the number of frost spots per plant and results showed that Fleece produced the least amount of frost stains. The plants under perforated foil again showed the most frost stains of all covering.
