Slurrycal is a dual purpose high ph lime blend for use in cubicles and livestock stalls. It is designed to provide high levels of protection against disease-causing bacteria in the cubicle and uniquely enhance the slurry.

Slurrycal has been developed in conjunction with several international technology companies to enhance the slurry when it is brushed down and mixed into the slurry tank/store.

Benefits of Slurrycal

• Creates a homogenous slurry
• Reduction in odours
• Breakdown and prevention of crusting
• Increased fertiliser value of slurry
• Reduction in agitation costs
• Promotes aerobic environment within slurry
• High pH helps protect animals from disease and infection



“Barryroe Co-op supplier John McCarthy milks an 80 cow herd in Butlerstown, Bandon, Co. Cork.  The herd is split calving with 40% calving to supply winter milk to the Carbery Milk scheme. Sustainable production of top quality milk is to the fore on this farm and this was recognised with John winning the 2011 Carbery Milk Quality Award.

Producing 550 Kg of milk solids with a stocking rate of 3 LU/Ha and SCC less than 100,000 requires a high level of management. This is further evidenced by the fact that the farm undertakes a selective dry cow tubing policy with cows under 100,000 SCC and no recent high SCC readings, receiving only a teat sealant at drying off.

The cubicle hygiene regime during housed periods involves liming cubicles twice daily with a cubicle lime blend. A total of 4 tonne is routinely used each winter. In October 2015, John decided to try out the newly launched product Slurrycal as he was interested in its claim to combine cubicle bedding and slurry treatment in one bag. For his stock numbers it was calculated that he would need 2 tonne of Slurrycal along with 2 tonne of a 10% blend – a combination used for the past two winters.

Having now used Slurrycal for the last 2 years John is convinced of its effectiveness. “It has the same drying capacity on the cubicle as the 10% blend and other cubicle products I have used and it is easier to work with because there is very little dust. It certainly does its main job of helping to keep cubicles dry, while also helping to maintain low SCC and low levels of mastitis.”

“When I started to agitate and pump slurry, I knew that Slurrycal had done its job as promised on the slurry too. There was no crust whatsoever, and the tank was like it had been aerated. The time it takes to agitate is well back and it stays agitated for a long time. The slurry is darker in colour with a very evident reduction in smell. The response in terms of grass growth when the treated slurry was applied was very impressive – I would say that the slurry is giving a response similar to what you would get from a bag of 27.2.5. 5. The grass is a healthier, greener colour and re-growths are quicker.”

Slurry is applied with a trailing shoe on all silage ground and on the grazing ground when the weather is dry. The splash-plate is used on grazing ground also. Silage and grazing ground with a low P & K index are prioritised for slurry application with grazing fields receiving up to 2 applications of 2,500 gallons/acre and silage ground receiving 3,000 gallons per cut.

“We are stocked relatively heavy but we are now applying less chemical fertiliser and still maintaining grass growth. The Slurrycal treated slurry is helping in this regard and the reduction in smell is an added bonus.” John is very impressed with the simplicity and dual efficiency of Slurrycal. Put simply he says, “lime the cubicles and the slurry is treated: as part of our daily routine of liming cubicles we now have treated slurry.” John also finds the cost effectiveness of Slurrycal is an added bonus: “for my stock numbers I only need to use 2 tonne to treat all the slurry on the farm; the extra cost of €400 is well worth it for the job it is doing.”

“I used Slurrycal on the cubicles during the past winter. The product was easy to handle and spread on the cubicles and there was very little dust; also there was a nice fragrant smell in the shed after it was spread. When I had to pump the slurry from the underground tank into the large overground tank I usually had to agitate for 3 hours and even still there would be large lumps left in the small tank after it was emptied; this year with Slurrycal I agitated for 30 minutes and was able to empty the tank completely and no lumps were left behind. This year after spreading the treated slurry on the fields; the grass was much greener and leafier than I’d ever seen after slurry application and I was able to cut silage two weeks earlier than the previous year even though the weather conditions were harsher than other years”.

“At first I was sceptical of the benefits of using Slurrycal but the agitation of the slurry tank in March told its own story. Normally agitation would take 2 – 3 hours from two external points; this year after using Slurrycal the tank was fully agitated after 30 minutes from one agitation point only! That saving in agitation cost and hassle alone makes slurrycal worthwhile for me. The slurry was spread after 1st cut silage and the 1st load out of the tank was the same as the last load- all liquid and consistent. There was no residue left on the grass as it spread evenly and was easily washed into the soil”
