Joe Sheehy: Use slurry after early grazing, before closing

Slurry has become a very valuable product. If used correctly, it can enable a great saving in purchased fertiliser expenditure.

Teagasc researchers put a value of up to €30 per 1,000 gallons on undiluted slurry, or the equivalent to one 50kg bag of 6-5-38.

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