Are you ploughing it all down? Have to forget about that until you plough it back up next year 😜 I always put fym K and salt, N
depending on how much muck and top dress some N

sugar beet but shouldn't be far away

Slurry could be 80 % washings
Impossible to calculate without a test
Sorry you seem to know yours but as a general rule
But if you have a lot of straw in it won't it use a lot up breaking the straw down

So, lots of assumptions but spring applied, standard values and all indices at 1.

Beet crop needs 80kg/ha p, 130kg/ha K, 200kg/ha na2o and 120kg/ha N

Your slurry and muck will supply 85.5kg/ha N,122kg/ha P, 523kg/ha K.

So you only really need to apply the balance of N from the bag and maybe some salt as beet love salt but you have got bags of K.

To convert kg/ha to units/acre X 0.8
