”We have been using Hi-Cal under prescription for 8 years. During this time we have seen a rise in our PH levels which is verified by extensive soil tests conducted, processed and reported by a third party soil consultant.

Hi-Cal has many logistical benefits for us. We bring it home during harvest and don’t suffer from wind blow like lime sands and also get a consistent 12m spread. The sum of all parts results in Hi-Cal being a cost effective and efficient product that we will continue to use.
”We started using lime sand from Optima Lime's Neil’s Pit at Boranup when it opened in 2016. The quality has always been high and the proof is in the results we are seeing on the farm. Boranup lime sand is the cornerstone of our pH management program.

“Optima’s range of manufactured lime products are faster acting as they are soluble. The lime moves through the soil layers leaving an impact across the whole soil profile, not just the top section. Optima’s lime products have made impressive changes to ph on our farms since changing over 6 years ago.”

“I’ve been dealing with Optima for nearing a decade. I switched to using Hi-Cal lime about 5 years ago and have been pleased with the results. These days I order through my local rural store. It couldn’t be easier.”

”I heard about Hi-Cal Lime several years back and admittedly, the perceptions seemed to be a bit mixed. However, I wasn’t convinced the standard approach to liming was delivering the results I wanted so I decided to take a punt and get a few loads of Hi-Cal lime. These days Hi-Cal is the only lime I use.

“I’ve been using the Optima Lime Hi-Cal lime for a number of years now and have confidence that it does what it says on the tin. It would have been easy to be put off trying something new but after seeing it for myself, I’m convinced these manufactured limes get working fast in the paddock.”

“For us Optima is a logical choice because they have the highest NV rating. Why would you want to pay to cart extra dirt when you could be carting extra lime instead?”

“We have been spreading Hi-Cal for 15 years. 500kg/Ha on rotation, so the country sees lime every 3 or 4 years. The soil pH keeps improving, even with the continuous no till cropping program over the past 10 years. Due to rapid pH change and the soluble calcium in the product, we continue to get great performance from chemical applications so keeping the crop clean is much easier. The economics from a manufactured lime continues to pay it’s way.”

“We have been using Manufactured Lime in the form of Hi-Cal from Optima Lime for over ten years. We can see a visual increase in crop vigour in season one of application and it is helping us grow better crops while looking after our soils. With the added benefit of back loading when delivering grain, Hi-cal works for us.”

“We deal with Optima Lime for our Lime requirements, they have the best quality Lime and are easy to deal with, they are willing to go out of their way to making ordering easy. Having the best quality and ease of ordering makes Liming hassle free.””
