Besides elements that should be present, there are elements that should rather be absent; you don't want to grow potatoes in a soil rich in arsenic or lead. IIRC, most analyzed samples of Moon regolith contain something that plants don't exactly like, but can tolerate. Some selection and / or genetic engineering may be required to produce plants that grow readily on regolith-based soils.
