Not sure at all but i suspect no.Looking at another frost tonite round here and I’m gonna try ‘washing the frost off’ the spuds. Is it worth dropping anything else in, manganese or mag nite
We had an unexpected frost Monday nite and it’s done enough damage already, so anything is worth a tryNot sure at all but i suspect no.
The water thing on a frost / pre frost is all about Entropy, Heat of Fusion and so on.
When ice thaws 334 joules of energy needs to be adsorbed per 1 gram of ice...this energy is taken from the immediate surroundings including the leaf the ice is on.
In a marginal frost on a delicate leaf this heat of fusion energy draw is enough to damage a leaf that might otherwise be ok...that is why irrigating warmer water, usually ahead of sunrise, sometimes works very effectively.
Did it help?I tried a field this morning. I will know better in the morning how effective it was, generally used about 500l/ha. on inspection it had made a good job of defrosting about half the plants. I used brown defy nozzles at over 4 bar pressure. I think lower pressure and a coarser spray pattern would have been more effective
