Aang is more in-tune with his spiritual side than I am and can probably give you a better explanation, but I'll give it a try from my own knowledge and experience. All living things have energy. It may not always be the same, but it's still connected. And the-- or an I guess an Avatar, now, with the knowledge of energybending can manipulate the energy in a living being.
All of that to say, yes, the energy around your farm is different from what I've been around before. Which is likely not a bad thing. There's lots of things around here that's different to me.
