Hi Charles and all.
I have taken on a previously dug allotment which has been covered by a black polythene mulch. It is currently weed-free.
I intend to buy in some cow manure to make some beds, but suspect it will be less than your recomended 1 year old and not be rotted down enough. I am not planning to plant anything until next spring, but I am wondering what to do until then…
Option 1 would be to stack the manure until spring and meanwhile sow a green manure (I thought rye grass)cover crop to boost the humus content of the soil, covering this with a 7cm (would that be enough?) layer of the by-then mature compost to kill off the green manure.
Option 2 would simply to spread the unripe compost now and cover with plastic. I realise this would be the simplest option but may not increase the organic content of the soil as much as option 1.
Any thoughts, comments or wisdom to impart???
