Effects Of Lightning On Plants

From the National Severe Storms Lab:

" The air in our atmosphere is about 78% nitrogen, but it is in a form that plants cannot use. Lightning helps dissolve the nitrogen (called 'fixation') into the water to create a natural fertilizer so plants can absorb it through their roots. Lightning also produces ozone, a gas that helps protect the Earth from the dangerous rays of the sun. "
