I think you may be correct. The council laid out a number of new allotments in an adjacent field and gave the new tenants 3 months to get going. Some of them simply covered the plot with black membrane in order to kill off theweeds etc before starting in the spring. What the h*ll this has got to do with me and my long term methods of cultivation is quite beyond me. There is no mention of covering in the agreement.
Incidently, I have raised beds and operate a "no dig" strategy. After the growing season I put compost on the top of the bed and cover it. It results in a perfect plot and I can start planting very early. My potatoes, which have been chitting since Christmas, will be planted before the end of Feb. This means that I can lift my main crop early July and get a second crop of say runner beans before the growing season ends. It also means that I usually miss the inevitable potato blight, which seems to have got more prevalent as more people start having allotments.
Funny old world. :)
