I'm busy carting in FYM to use on brome infested stubbles post harvest.A poor mans manure, use FYM/digestate/sludge/compost and there is no need for cover crops.
Unless you are grazing them with livestock!

I grow a lot of stewardship funded winter cover crops as I am 50% spring cropping here. Direct drilling all crops. Until I can get a disc drill that will sow directly into standing green cover crops I have to spray them off in Jan/Feb to make sure most of the biomass has gone by the time I want to drill in March. As above, they don't remove much soil moisture at that time of year so a thick canopy will only slow drying. Direct drilling always means being more patient in spring and the last few years have seen wet March weather forcing drilling into April then we've had dry conditions afterwards which don't favour late sowing. Spring crop yields are a bit below what we used to get especially on the last sown land.
On the plus side, I haven't had any soil erosion outside steep tramlines or farm tracks for years since moving to this system & the soil health has definitely improved. Worm numbers are increasing & I know this will be more resilient in the longer term.
I agree with you but its the spending now for maybe a benefit in 5 years which is hard to comprehend . My current system [FYM / S Cake] is a shorter pay back and is really obvious in following crops.Looking at a single year in isolation they often add costs and work, not always providing a benefit in terms of yield. Cover crops have to thought of as a long term plan to invest in the soil, which will pay dividends down the line
