Really!?Snow has a very high bacterial content. If it is ploughed, say, 8'' under, it doesn't do the soil any good and it will take several years to recover.
That exhausts my total knowledge on the subject.
I have just Googled '' bacteria in snow''. There are plenty of references, but I can't find any reference to the harmful effects of ploughing it down.Interesting idea. Is there a reference to this anywhere?
Ford used to have an advert showing its tractors ploughing in extremely wet boggy conditions, boasting that other tractors didn't have the necessary grip.Think it's a old wives tale personally. I've ploughed in snow until tractor can't get grip. Then come back and finished on a dry spring day and no difference in crop
