Yes, have seen it done with lambs, but not sure there is any advantage for cattle.
I usually do rape but I find with usual late sowing from late harvests it never does much, would Westwolds yield that bit better if sown mid August than rape ?
the plan was to sow it now and be able to graze it in september and hope to graze any regrowth again in early spring. I'm just not experienced enough to trust that it would supplement for the loss of second cut that I'll be relying on.
Yes it will grow better later in the year but as I said managing the crop will be difficult
CC was ensiled on the first week of May, estimated at 4.4tDM/ha. Then 30t/ha of fresh fym. Planted 20th May with 50kg of DAP (18-46-0) placed by the seed. Photo today.
Sunflowers planted into CC of clover and vetch. CC was disced twice and ploughed down. No fym, no artificial fert, just weed spray and close the gate. Rotation is (CC) maize, wwheat, wbarley, CC, sunflowers, CC +fym and back into maize. Pic #1.
Same type of rotation, same kind of land. Wheat that wasn’t worth going forward with was disced and 30t/ha of well composted fym applied before ploughing. It also got 50kg/ha of DAP.
Both sides of the pole had a CC of clover. On the left the CC was removed, on the right it was left in place and ploughed down. It’s not so evident from the photo because I’d to stand on the bonnet of the Jeep, but the parcel on the right is much higher and dead even. Both goth 40t/ha of fym in 2018 and nothing since. No fert applied.
Looks a super colour and uniformity
Pic #1. Planted after removing a CC of clover and vetch.
Pic #2. Same variety planted the same day but after a failed crop of wbarley.
DD maize in land that is no-till for 7or 8yrs. Pic #1 had just weeds and crap on it before drilling.
Pic #2 had CC of beans and vetch.
I know that both are crap but one probably won’t be harvested...
That's fair drastic. Shows the benefits of holding onto and fixing nitrogen
I honestly don’t see any benefit whatsoever using non-fixing CC mixes on land. Yes they will aid subsequent tillage operations, and help soil erosion, but there’s no real benefit to me as a farmer.
The EU only want non-fixing CC mixes to mop up any stray nitrogen but they’d have to pay me to grow them. The only *real* and quantifiable benefit I’ve seen are from good clover and vetch mixes.
I know I’m going against the grain in saying that, but it’s my experience on this land....
Do you graze much if any of your covers?
Squarrosum clover @Sheebadog ? What Seeding rate on its own ?
balansa clover is a tiny seed compared to say crimson clover which is normal size we’ll say
How does Squarrosum Compare
What would your ground temp be in winter
If it likes wet cold winter conditions ??? Well it might just suit Ireland ?
No we don’t. No fencing or water etc. Anyhow I think it’s going against the principle of CC to graze it with livestock...I’d lose out on biomass, fixing of nitrogen, soil structure building etc etc. Some guys are bringing in graziers with sheep, but I fail to see the benefit.
Seeding rate is 30kg/ha on it’s own, but I wouldn’t go past 15kg and include the likes of vetch with it. It’s about the same size seed as crimson.
We can get a temperate or continental type winter. Most years we get a fortnight or so of -8 to -16, but not last year, we got a wet Irish kind of winter.
Of all the cover crops I think it would work very well with winter vetch in a mix, for Irish conditions.
I’ll try some, as fai as I know winter vetch is hairy vetch and most vetch types we get here are spring vetches and don’t suit late sowing
I’ll find some winter to mix
We use this vetch. It also has an agressive growth rate so it can hold its place with the clover. It’s root ball system works well with the tap root of the clover and goes plenty deep even during winter dormancy. Cold and wet are no bother to it so is very winter hardy.
Do you gave a English name for it?my French isn't very good
Winter hairy vetch.
The variety we used last year was Latina, I think, but I’m not sure
This bit of research seems to back up my theory on multi species cover crops...
My WBC has gone from wilting with the heat/drought to as of now mostly under water:(
Summer cover crop after the Oats. Probably spray it off end of September and sow winter wheat.
What's in the mix Bog Man?
It was some left over from last year.
