we deliver fertilizer once a year to airports around the area...
and these planes load in the front.. and fly over planted pines throwing fertilizer from above,
i talked to a ground guy there, once because i thought it was a waste to fertilize a pine field with at least 8'' of pine straw on the ground....
'' i just couldnt figure out '' how the fertilizer would get to the root, network with all the dead matter that is on a forest floor,
but he said it really works, and theyve done studies, that showed that fertilized pines were ready to harvest
5 years before unfertilized pines,
[ im sure that will be on the list of useless knowledge i will remember forever ]
