The standard rate here has usually been 75-25, with the farmer paying all input costs. About the only thing the landowner was responsible for was to keep the land limed, and even then I've seen that cost split. I once rented a farm on the 2/3-1/3 shares, with the landowner paying a third of the seed, fertilizer, and chemicals. 80-20 is new to me. Most of the land here is cash rented, and prices have come down some over the past few years. I'm somewhat lucky in that the neighbor that rents mine is still paying me the top dollar of a few years ago, but I also let him grow tobacco on the land and don't ask for extra. Most tobacco farmers who lease land have to pay at least double the corn and soybean rent price because tobacco is a crop that pulls a lot of nutrients out of the ground.
