I am having a hard time understanding the obsession with nitrogen fixing trees. Nitrogen is not a hard thing to come by, so why waste space planting a whole tree for it? I get the shade & mulch, but the argument for nitrogen really baffles me. Unless you have no animals or are afraid of humanure & urine

Saying this as someone who does not have acres to work with. Otherwise can see planting one with plenty of space
