    Proposal summary:

    Asparagus is profitable, but weeds are hard to control in organic gardens. The farmer will explore cover crops and cover materials—wood chips, Dutch white clover, crimson clover, buckwheat, and a mix of cruciferous annuals like mustard, rape, and kale. A control plot will be cultivated mechanically and test plants will be monitored for vitality. As the beds mature, the number and weight of the spears will be recorded as they are harvested to determine the effect of the different weed control strategies.
