To plough or not to plough

I have a small 4 acre field that is going downhill fast. Moss is appearing, rushes are growing everywhere and the soil is literally oxidising.

The ever helpful Damian McAllister from DLF seeds visited me last week to check my multi species reseed and we had a walk through this field to brainstorm how to tackle it.

thought I would plough in farmyard manure and some BAM and humus from NewGenAgri to get good nutrients and biology pumped in with hope to get it kickstarted with another multi species mix. But Damian suggested I direct drill a brassica after weed wiping the rushes. The brassica will grow tall, hopefully drowning out the light to keep the rushes back. A deep tap root will do wonders to get air into the soil.

Give it one pass of grazing and direct drill the multi species into to it later in the year.

Trying to work out the cost and effect benefits of both options.

I guess the rushes may just come back this year if I go straight in with multi species mix and then I can't spray it back. But paying for two direct drill contractors and seeds in one year with only one grazing out of it may cost more but could have beat long term effect.

Anyone have any thoughts to further confuse me? Haha!

Seriously I'd love to hear any thoughts on this.
