It's true! Lightning can make your garden grow


I went looking for an explanation for why our dead and dying plants ahve suddenly revived after a series of hefty lightning and thunder storms. And I found it at www.ucar.org, the University Corporation of Atmospheric Research. They explain it this way:

"Atmospheric nitrogen becomes part of living organisms in two ways. The first is through bacteria in the soil that form nitrates out of nitrogen in the air. The second is through lightning. During electrical storms, large amounts of nitrogen are oxidized and united with water to produce an acid that falls to Earth in rainfall and deposits nitrates in the soil." Nitrogen is present in superphosphate which farmers pay heaps to spread on their fields. Lightning is like free fertiliser.
