Quantity of Slurry / Acre

[sheep&cows&stuff]

For fist cut I spread 4,000 gallon of slurry per acre (Mixture of suckler / milk / duck / digester slurry)

For second cut at the weekend there I spread 3,200 gallon of slurry per acre (Mixture of digester / duck slurry)

First cut got 3 bags (150kg) of fertiliser per acre also but as have surplus silage this year no fertiliser has been sowed on second cut.

How much are other people applying? A neighbour flys over the land and spreads about 1,000 gallon an acre - to me it hardly seems worth wile.

Digester / duck slurry mixture comes from a neighbour who has the contract of drawing this away from a digester and a duck farm.

RB209 is your friend. Even available online these days. Convert your "old" imperial figures to metric as it makes calculations much easier.
From that work out how much available N you have applied (Plus PK & S) then see if there is a shortfall. Duck slurry probably makes for quite a pokey N mix but if applied in hot weather, losses will be higher.

If you have had sufficient from 1st cut, then I wont bother with fert.
As a rule of thumb, we apply 3000 gallons/ac (or 34 cu.m/ha) at each cut of cow slurry then top up with Kaynitro but we do 5 cuts or so and need the grass

Do a dock test before you have imported slurry , may be the most expensive slurry you ever had for nothing

The contractor i work for pretty much always spread around 20m3/ha sometimes 25 if it's close by, no real difference between different cuts.
Got to put 30m3/ha on once... felt like the fields would never end.

60m3/ha on every cut of silage, 20m3/ha behind the cows all injected
