Hay & Pasture

How does liquid calcium affect hay & pasture?

One of the biggest factors that impacts plant productivity is having nutrient-rich soil. Soil with lots of hydrogen will naturally be more acidic. Acidic soil prevents nutrients from going into the plant and thereby decreases plant productivity.

To combat this, liquid calcium actually displaces, or moves, the hydrogen out of the way, allowing more nutrients to enter the plant. As the hydrogen is getting displaced, it causes the pH of the soil to increase, making it less acidic. As pH increases, so does plant productivity.

Which fertilizers should be used with hay & pasture?

Nitro-Maxx+: Nitro-Maxx+ is the next generation of nitrogen application. Nitrogen is such a crucial nutrient for ensuring strong, healthy growth. However, the hassle and risk involved in application has seemed inevitable. With Nitro-Maxx+, those major risks and issues are significantly reduced with our slow-release liquid nitrogen. Designed to release over time to decrease burn and dissipation.

3-18-18+: 3-18-18+ is a liquid solution with the best source of potash and phosphorus that is immediately available to the soil. No need to wait for rain or for breakdown times, 3-18-18+ can be easily applied during many stages of growth to ensure crops are getting the phosphorus and potassium they need for the best possible growth.

10-20-10+: 10-20-10+ is part of our orthophosphate fertilizer program. Orthophosphate fertilizers are the fastest and most efficient way to provide nutrients to the soil and to the plant. This form of liquid fertilizer supplies the nutrients to the soil immediately with no breakdown time or risks of loss like standard fertilizers.

Bio-Act: Bio-Act is a nutritional plant supplement that can be used as a soil treatment, seed start, or foliar feed. Bio-Act contains a blend of micronutrients and minerals that provide a unique source of nutrition to the plant and to the soil. This blend of micronutrients also contains humic acid which provides valuable nutrition for the plant and adds feed value to the crop.

We always recommend applying bio-activated liquid calcium.


“It has done amazing, completely knocked out my sedge grass. It was thick and green all year last year. This product worked better than I expected. I need to get some more ordered.” Isaac | 2020

“I am amazed at our hay production after applying Advanced-Cal. We usually average 39 bales, but after this first cutting we doubled that!” Dusty D. | 2020

“I applied the Pro-Cal before my first cutting. I went from 63 in the past to 85, but then I sprayed 9-18-9 and my second cutting was 143 round bales. That is one heck of an increase. At 250 bales, I made $14,500 more. You told me that I needed to use your liquid fertilizer and raise my phosphorus and potassium. I had my doubts, but this proves you were right.” Larry W. | 2019

“Last fall, I applied 3 gal Bio-Liquid cal per acre on my fields. I normally get 14 1,000 lbs bales, this year I got 30.5 1,000 lbs bales, that’s quite an increase in hay.” Frank K. | 2019

“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! Worth every penny!!” Allen S. | 2020

“I applied Pro-Cal last year to some hay ground and some corn ground. We did before and after soil tests and the pH balanced out and it made great hay, and now this year I can see exactly where I sprayed at where I didn’t. I’m not gonna lie to you, I thought this stuff wouldn’t work, but I was wrong. It worked great! Crazy to think this did the same as 2 tons of lime with so much less.” Richard M. | 2021

“I applied this to my hay ground in Michigan. I appled in the spring and tested the ground come fall and my pH had gone up a whole point. I was amazed.” Mike H. | 2021

“My hay fields have never looked this good. My customers are very pleased. So far all I have put on them is the 3 gal Advanced-Cal. The weeds are gone and the field is very clean.” William S. | 2022

“I put that Pro-Cal out last year. I have a place that is very low pH and I have tried everything and can’t grow anything on it. I put the Pro-Cal on and planted wheat. I was able to run 84 head of cattle on that 91 acres all winter long. I was shocked, that ground has never been able to grow like that.” Kenneth B. | 2020

How does ag-lime compare to liquid calcium?

Ag-lime has a pH neutralizing (carbonate material) effect on soil after 6 to 8 months from application, but does not immediately correct soil calcium deficiency. In contrast, liquid calcium goes to work in one hour.

Liquid calcium is mined from the ground in the same way that limestone is extracted and pulverized. But unlike limestone, the process doesn’t stop there. The crude material goes through a process of heating, liquifying, and then extracting the pure soluble liquid calcium, doing away with all the sediment that would normally end up in your soil, and chelating the calcium to make it ready for agriculture use. The raw calcium is then mixed with carrying agents, surfactants, and chloride to make the ease of application and delivery simple and very effective. Chloride in this small amount is proven to increase photosynthesis in the plant creating faster and stronger growth, and also increasing drought resistance and disease resistance and suppressant. Please note, chloride in this form is not the same as the crude chloride used on roads and in tractor tires. Just as some forms of lime are used for hardening soil before construction, or to be mixed with concrete, there is a distinct difference and importance in understanding ag grade products meant for agriculture purposes, and crude material used for construction or in tires.

University backing of liquid calcium

AgriTec has land grant university research from multiple universities, showing how calcium changes soil pH, and just how crucial and important calcium is to the soil and to the plant. AgriTec continues to conduct studies and build further evidence that calcium is more effective than dry lime and raising soil pH and improving soil conditions.

"Liquid calcium chloride, an often-overlooked nutrient, is essential for plant growth. Deficiencies of this nutrient have been verified in Kansas. Chloride is essential for photosynthesis and serves other critical roles in plants. Plants take up chloride as the Cl- ion. This ion is very mobile in the soil and is subject to leaching. Soil testing and plant analyses have proven useful in identifying potential deficiencies of chloride. Recent Kansas research has verified a need for chloride fertilization on some soils."

"Unfortunately, the role of calcium in plant nutrition is often eclipsed by interest in macronutrients or specific micronutrients. Many are overlooked and only considered when deficiency disorders influence the economic threshold of produce quality and value. However, we know that calcium 1) is a multifunctional nutrient in the physiology of crop plants and 2) in the soluble form influences availability and uptake. Nitrogen-use efficiency of urea-containing fertilizers is also increased with soluble calcium sources such as calcium nitrate."

"We apply fertilizer nutrient materials to the above ground growing portion of the plant. We have seen that materials are absorbed by the plant and move rather freely in the plant. The amounts may at first seem relatively small, but to offset this handicap, the efficiency is high. In fact, this is the most efficient method of applying fertilizer to plants that we have yet discovered. If we apply these materials to the leaves in soluble forms, as much as 95% of what is applied may be used by the plant. If we apply a similar amount to the soil, we find about 10% of it to be used."
