P and K can be maintained by putting all the slurry in silage area

This has been an exceptional year providing an unusually good opportunity to spread slurry as soon as the closed season ended in mid-January.

Teagasc researchers put a value of up to €28 per 1,000 gallons on undiluted slurry.

About 85% of the value comes from the P and K, but if slurry is spread in the spring, much of the N (worth €5 per 1,000 gallons) can be utilized.
