Reaction with soil chemicals to produce nitrates. It's basically the same way in which NOx created by lightning is converted to nitrates. And unless you happen to be a legume hosting a bunch of nitrogen-fixing bacteria, that's where the nitrogen needed for growth ultimately comes from. (Yes, that's over-simplified, 'cause a lot of the available nitrogen gets recycled in animal droppings &c.)

As for ocean acidification, that's almost entirely caused by increased atmospheric CO2, which dissolves in seawater to produce carbonic acid: Ocean acidification - Wikipedia, the free encyclopedia
