The solution is so simple. Crop/pollen diversity. Instead of letting fields lay fallow for crop rotation, they could plant diverse wildflower meadows to improve quality of bee health for the traveling bees that get shipped around for crop rotation. Or the bee keepers themselves that sell the services of their bees, could ensure diverse flower and pollen options when their bees aren't traveling.

I can see a potential problem with this suggestion. How many of those wildflowers are net nitrogen fixers? If they are net-negative this approach could be draining all the nitrogen out of the soil during off-rotation years meaning large amounts of petrochemical fertilizer would have to be used to make the field productive again for nitrogen consuming crops (like wheat and corn).

Key Native Nitrogen-Fixing Wildflowers:

  • Lupines (Lupinus spp.): Includes Texas Bluebonnet and various perennial species; they thrive in poor soil and are loved by pollinators.
  • Prairie Clover (Dalea spp.): Purple (Dalea purpurea) and White (Dalea candida) are drought-tolerant perennials that fix high levels of nitrogen.
  • False Indigo (Baptisia spp.): Sturdy perennials with showy, pea-like flower spikes (e.g., Blue False Indigo).
  • Partridge Pea (Chamaecrista fasciculata): An annual that grows rapidly, making it excellent for disturbed soils.
  • Wild Senna (Senna hebecarpa): A tall perennial that produces yellow flowers.
  • Canada Milkvetch (Astragalus canadensis): A hardy, native perennial.
  • Groundnut (Apios americana): A vine-like wildflower with edible tubers.

Bees went fucking nuts for my lupine, even while living in an urban environment. Only problem was that the aphids did too. So many that it was revolting. I had to aggressively remove them every single day of the colonies would explode and destroy my lupine within a very short time. They'd suck it dry.
