Hi, how long after application of 2500gal/acre fattening pig slurry could a man cut silage? Ground got no chemical application .
Wouldn't be sure really but could depend on the amount of rain fall. I'm guessing about 2 weeks.
Got plenty of rain thanks. It's out 2 weeks and I sent a grass sample for analysis. Thanks
Would you not need to walk the ground and see if it has been washed in? Any slurry on the leaves would mean no go.
Why would you have put pig slurry out on grass only 2 weeks away from being fit to cut?
Slurry is washed in. Contractor was to put out weeks ago...
Pig slurry is supposed to have 10 units of N per1000 gals so 25 units N in 2500gals.
Grass would be using 2 units/day at the moment so two weeks plus it'd take a week to start working.
Even after three weeks I wouldn't chance it
Grass should not be cut for a minimum of six to eight weeks after surface spreading to allow sufficient time for harmful clostridia bacteria to drop to safe levels for a good silage fermentat
Just for your own sake for future reference if grass is that close to cutting you’d have been better off to take a light cut off it a few weeks back and put the slurry out then after.
For the reasons Wrangler outlined above and also there must have been a lot of grass trampled on with the tractor and tank when spreading. You probably won’t have gotten much value out of the slurry at that stage either.
