Sorry. I once had a high school chemistry teacher explain how snowfall fixes atmospheric nitrogen (lightning also works) but I could not explain it now if my life depended on it.

Re: Good Friday snow (4.00 / 3)

I believe it's mostly a trapping effect. There's a constant nitrogen exchange from soil to air in winter, when vegetation is not drawing on the soil's nitrogen resources; this is particularly true of fields left bare, ploughed before winter, etc. Snow blankets the ground and prevents the exchange taking place. Mulch will do the same thing.
