| I don't rely on it think I put on quite a bit more then most people. But I know on good years with plenty of rain you hit good areas that has to be getting the n from somewhere other then applied. This year my fields got 60 lbs preplant urea. Then I sidedressed 160 n with uan. Then my dry is changed for different fields so considering n from dap I ended up about 255-275 of total n for each field so I would think I am quite a ways away from mining it lol. | |
