How does liquid calcium affect weed control?

Soil pH has a large impact on the availability of aluminum. This is important because soluble aluminum restricts plant's access to water and nutrients. It isn't that weeds love acidic soil, but rather they survive in acidic soil where most other plants cannot. 

One of the largest factors for soil pH is the hydrogen concentration. 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.

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 research from 9 different Ag Land Grant 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." 

Dr. G. W. Easterwood Calcium's Role in Plant Nutrition

"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."

Testimonials

"After applying Pro-Cal, I have the best-looking fields in years. No broomsedge."

William S., 2021

"I'm really happy with it. We usually do 4 ton of chicken litter every year. We decided to just spray the Advanced-Cal this year. Our weeds were reduced significantly and we had great growth. We were tickled to death over the results."

TX 2021

"I put y'alls stuff on in March and I'll tell ya, by June I could see a huge difference in color and could see the weeds start dying at the root. It was amazing! By the second cutting they were almost completely gone."

George S., WV 2020

"We applied three gallons per acre of Pro-Cal and this year we don't have any buttercup and the other weeds are gone."​
