Would you plough your new allotment

I sprayed the area of my garden where I made the Veg Patch (and the flower borders too ...) with Glyphosate to kill the rough-grass, had the farmer plough it, and then got a tractor mounted rotavator.  Then I started using it!

Glyphosate won't work this time of the year, plants have to be actively growing for it to be effective (and Bindweed etc. will have no leaf at all at this time of year)

A Farmer's plough has two blades. There is a little blade (called the weed board maybe?) that scrapes the top inch or two, and that drops into the bottom of the furrow created by the adjacent large mouldboard, and then the actual large mouldboard turns over the soil - say 6" or 9" - on top of it.

So, in principle, the weeds will be buried.

A plough will break up the weed roots less than a rotavator will, but I'm not sure that what you are left with will be easy to work - it will all be uneven.

Although if we get a nice cold February that will break the soil down a lot.

If you have perennial weed roots in the soil then rotavating will chop them all up, and each one will make a plant - they aren't "weeds" for nothing!

A farmer would follow the plough with something to make a seed bed. That would leave you with a level surface that was easy to dig / plant.

You could "take a chance" on rotavating in the first season, but you might have a lot of weed as a consequence.

For fertilisation purposes, is there anything recommend for spreading onto it before ploughing to help the fertilisation of my plot?

P.S. Its not really for fertilising the plot, more for improving soil structure. Manure will add some nitrogen, but you can sprinkle fertilizer or use chicken poo pellets for that

I know in theory you shouldn't rotovate  a weedy plot but if it is very compacted to start with at least when rotovated you are able to fork out all the weeds that regrow a lot easier than when the grounds solid, even if it's mares tail. Now I know lots of others are going to disagree with me but exactly that was my circumstance when I took over my plot.A couple of years on it's loads better & i've grown loads of crops.

I had mine ploughed then 'scuffled'. The ploughing turns it over at which point I took out the worst clumps of weedy sod. Then the guy with the tractor harrowed it which pulverises the large sods.  I again picked out the worst clumps

Thereafter I dug down about one and a half to two feet and removed all the perennial roots. There is nothing better than doing this.  There was one area I then covered and planted potatoes through holes in the weed fabric and this was tickety boo once i got out the spuds.

Ploughing alone will help breaking new ground so get it done. Look on Youtube for ploughed ground to see what it ends up like.

A plot is hard work and it shoes if you don't put the effort in.
