Leeks after potatoes in the same sacks of different composts, one of soil

On 18th July, I transplanted leeks into the same six sacks we had just harvested potatoes from, see previous video https://youtu.be/klrUA_nbFI4. The leeks had been sown 5th April, then potted on in the greenhouse.
I did not feed the leeks nor did I add any more compost. The idea was to discover what nutrition and growth quality remained in these composts during the second half of the season.

We return 16th October for the harvest, it's really interesting!

* Please note that when introducing the trial at the start of the video (01.00), I say I am going to plant potatoes, but mean leeks!*
For the potato trial there had been seven sacks, but one was horse manure which turned out to have weedkiller, and therefore that one is not in the leek trial. I had spread the horse manure over nearby grass and then it is dissipated in sunlight.
