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 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.
