How much Nitrogen in Pig slurry?

fulljonny

Hey guys looking at getting more fertiliser just got to make sure I'm under the 170Kg mark.Imported 150k gallons of pig slurry for spring barley first time importing pig slurry so not sure what the department take as the nitrogen content for this?Any help would be great thanks in advance!!

Pig slurry contains 4.2 kg N per m3

150000 gal(UK) = 681.913 m³

http://www.metric-conversions.org/volume/uk-gallons-to-cubic-meters.htm

682 X 4.2 = 2864 kg N

I'd wait for some more replies though if I were you.

Ya thats what I found on the internet aswell but that 4.3Kg of Nitrogen isn't all available.So not sure if that's how the department calculate it.

Makes no odds on availability when doing records for Nitrates.

It's the same figure in the Govt. Statute Book

Scroll down to Table 7

Farmer Pudsey

Try to spread in damp/lightly wet weather and plough or disc in if weather is not damp/wet. Avoid windy day like the plague.

The actual composition of pig slurry in the tank in units is N37/P12/K18 according to the Farmers Handbook.


In the wrong conditions only about 10-15%N available in the ideal conditions 50%N available. Disc or plough in a as soon as is possible.

Thanks guys now I know where I stand can never be too careful when it comes to the Nitrates!!
