ive been around these fields nearly my entire life. We own a bunch of land right next to them. So i've been around the process for a while and they have already sprayed the fertilizers for the rest of the year. The only other thing that is sprayed is the pesticides. The only thing is i dont know when my plant will start flowering! So i dont really know if it'll be near harvest when they start spraying. Most crop dusters do a poor job anyway so im sure they'll just spray the easiest spots to get too. I'll plant somewhere that isnt easily sprayed.
