Try planting pumpkins for a few years and see how it goes. Maybe even try some butternut squash. They do require N to do well. I dig hills about 10 feet apart, digging down 5", spread some fert., add soil over, then 4 seeds on each corner, one in the middle for the crow. Cover. Hoeing around the plants help, and I'll even hill them, once the plants get some size.
The nice part about pumpkins, the whole field need not be worked. An area, size of a trash can is all they need.
