"The preliminary research results from Tuskegee and our producers' farms indicate that your products are promising. For instance, your liquid calcium products have increased soil pH here at the University." Dr. Frank Abrahamsen, MS, Ph.D.

Pro-Cal™ is a liquid calcium derived directly from dry limestone that allows you to raise your soil pH faster and apply the product easier. AgriTec has years of before and after soil tests and thousands of happy customers to back up our products.

Pro-Cal™ is a pure liquid calcium designed to supply the soil with needed soluble calcium in a fraction of the time that is takes for traditional ag lime to break down.

Pro-Cal™ cation levels in the soil quickly and efficiently.

Pro-Cal™ eliminates the normal 9 – 12 month breakdown time involved with standard lime allowing the soil to immediately begin purging hydrogen and getting the calcium that is needs.

Pro-Cal™ last in the soil for multiple growing seasons.

Pro-Cal™ is easy to apply through a standard single point, dual point or boom sprayer, and can also be applied through planters.

When using standard lime many impurities are left in the soil, causing soil hardening over time. Pro-Cal™ is made by extracting the same calcium in lime and liquifying it into a concentrated state ensuring that the soil is getting only what it needs.

“My county agent saw a world of difference in our soil report this year over last year. Last year he recommended 3 tons of lime per acre. After applying 3 gal of ProCal per acre this year he said our pH was in the mid 6.4 range and we didn’t need any lime, he couldn’t believe the results.” John, 2021

“I did a side by side in a field. The average soil pH was 5.4 in a 40 acre field. I applied 4 tons of ag lime on one half and applied 3 gal of pro cal (per acre) on the other. Applied both in the spring. By the end of June pH levels where the ag lime was spread was 5.5 and where the liquid calcium was applied, it was 5.8. In the fall I sampled again, Ag lime was still 5.5 and the pro cal was 6.3. The next spring I sampled, ag lime was 5.8 pro cal was 6.8. The fall sample showed ag lime 5.9 and pro cal 6.9. The following year (year 3) spring. Ag lime was 6.1 pro cal 7.0. That fall as lime was 5.9 and procal 7.1.” Derek N., 2022

“We purchased a piece of property that had been clear cut of pines. After grinding approximately 15,000 stumps and spending hours clearing the brush, we had a field ready to plant. Unfortunately, the acidic pines had left a soil pH of 4.6. We applied your bio calcium on the ground in September of 2018 and planted oats. The oats turned out great. When we repeated the soil test in March of 2019, the soil pH had risen to 5.8! We were very impressed. We plan to do the same thing to another 10 acre section we just got cleared. We truly believe in this product.” C Welch, 2019

Liquid Calcium has been studied and proven by land grant universities that back the effectiveness of liquid calcium in fixing soil conditions and improving growth. AgriTec has been a family-owned company since 1976 and has helped thousands of farmers around the country over the years.

What Pro-Cal Can Do

On average an additional 2 round bales per acre on hay.

On average, an 8-12 bushel per acre increase on beans.

On average a 25 bushel per acre increase on corn.

Pro-Cal™ faster and more effective than lime

Pro-Cal™ neutralize soil acidity

Pro-Cal™ build soil base saturation increasing nutrient movement and absorption

Pro-Cal™ increases the efficiency of fertilizer by 50% or more

Pro-Cal™ reduces soil compaction

Pro-Cal™ strengthen cell wall in plant

Pro-Cal™ promotes root development

Pro-Cal™ is cheaper per lime

Calcium serves many purposes for a growing crop. It is the trucker nutrient meaning in order for nitrogen to enter the soil or to reach the plant there needs to be sufficient levels of Calcium in the soil.

Healthy soil has a base saturation of 75% Ca and 15% Mg. Soils with low pH indicate these levels are low resulting in wasted fertilizer, increase chance of weed, and lost production. Pro-cal ™ fixes that need and begins increasing soil calcium levels as soon as it touches the ground.

Pro-Cal™ is on average half the cost of limestone.


“Last year the weather was terrible we had a hard winter and record-breaking rains. Over all considering the weather the product did very well our pH went from a 5.1 to a 5.7 this year and that was with us only applying just over 2 gallons to the acre. Looking forward to seeing what 3 gal to the acre will do this year along with the Ortho phosphate 9-18-9 fertilizer.” Cliff 2019

“You said this would get rid of my broom straw weeds and bring up my soil pH , it did just what you said it would on 10 acres so I am ordering 110 gal to use on my other fields. I want to try your BioActivator next.” Martin T 2016

"I followed Agritec's complete system. I am very much satisfied with this program. After applying the liquid calcium, 1 lb. of N to raise one bushel of corn was just proven on my farm to be not true. We live in the day and age where it is time to step out of the box, away from the mainstream and try to utilize all the minerals left in the soil, plus add all the known minerals and nutrients, not just a few.” Greg L. 

“It works wonders quick especially if you have really low soil pH like mine was! I doubled my hay yields in one season! I was amazed because I don’t believe in anything till I see it in action and no I don’t work for agritec! Lol Worth every penny!!” Allen S., 2020 

“I can say we tried it out for the first time on a field that had a lime problem and it totally worked. [We will] spray more of our crops with it this year! We haven’t tried it on hay but would like too. Been hearing that it works best on hay ground.” Matt R., 2018

“My neighbor used you guys. His fields look better than everyone else’s. One guy asked him why that was, and he said he used your products. That’s why I bought some.” 2019

“Well Procal did what you said it would, I had no weeds in my oats. I usually have to use herbicide this year I didn’t. It was a very clean harvest.” John M., 2019

"My hay is so thick, and greener than I have ever seen it. My neighbors want to know what I am using. I have been telling them about the liquid calcium and Gro. I may need to order more Gro for my second cutting. I saved money on my fertilizer and nitrogen like you said I would. "Larry W.

"I sprayed BioActivator and Liquid calcium on my beans three weeks ago; I can already tell the difference, they look so different from the other beans. I am going to use it on everything next year." - Tim B 

"Those two totes of liquid Calcium I bought from you did wonders on my pastures. I haven't ever seen anything like it. My neighbors keep asking me what in the world did I do to my pastures and fields; it completely killed all my weeds. This is the best hay I have ever had. My friends and neighbors will be calling you, and I am telling everyone." Charles S

"I put the 55-gal Liquid Calcium and BioActivator on my worst fields, well I am here to say that field look as good or better than my best hayfields, that's why I am ordering a tote of Liquid Calcium and enough BioActivator for all my fields. Never seen anything work like this." Ron R 2017

“Please see the attached soil reports. We purchased a piece of property that had been clear cut of pines.
