Liquid Calcium in Agricultural Soil Microbiology​

In the intricate world of agriculture, achieving optimal crop production hinges on the intricate interplay of chemical, physical, and biological factors. Central to the biological dimension is the role of microbial bacteria in the soil, which forms a symbiotic relationship with plants, promoting their growth and enhancing soil health through various mechanisms. This complex microbial world, bustling with bacteria and fungi, forms a symbiotic relationship with plants, aiding in nutrient cycling, organic matter decomposition, and plant growth enhancement. Central to amplifying this beneficial microbial activity in the soil is the role of liquid calcium, which has emerged as a key player in enhancing soil microbiology for optimal agricultural outcomes. Learn all about the transformative power of liquid calcium in agricultural soil microbiology. 

What Does Liquid Calcium Do?: ​

Liquid calcium is not just a nutrient; it is a catalyst that significantly enhances the microbial life within the soil. By providing a readily absorbable form of calcium, this soil amendment improves pH balance, soil structure and nutrient availability, creating an environment where beneficial microbes can thrive. Various products have showcased the profound impact that it has on soil’s microbial ecosystem, but AgriTec International’s product, “Pro-Cal”, stands out for its fast-acting nature, offering a more efficient and precise method of delivering calcium and other nutrients to the soil compared to traditional liming techniques.

AgriTec has been a frontrunner when it comes to developing, researching and specializing in liquid calcium-based solutions that foster microbial activity in the soil. Their efforts have not only proven the efficacy of liquid calcium in improving soil health but have also highlighted its role in sustainable agriculture practices. By facilitating the rapid amendment of soil pH and enhancing nutrient availability, AgriTec’s liquid calcium products ensure that plants can access the essential elements they need for optimal growth. The result is a more vibrant, resilient, and productive soil ecosystem that supports healthy crops. Along with Pro-Cal, AgriTec also produces products like “Bio-Act” and “Folar-Act”, both of which help improve the synergy between microbial enhancement and plant nutrition. They not only supply essential micronutrients and growth stimulants but also actively promote the proliferation of beneficial soil bacteria. The increased microbial activity catalyzed by liquid calcium leads to enhanced nutrient release and solubility, improved germination, vigorous root growth, and elevated natural defense mechanisms against stressors in the plants.

What Are The Benefits Of Enhanced Microbial Activity?:​

The integration of liquid calcium into soil management practices carries with it a plethora of positive outcomes, such as the enhancement of microbial activity facilitating the breakdown of organic matter and releasing a treasure trove of nutrients available for plants to take in. 

In an article written by Dr. Erica Bizzell for the American Society of Microbiology, she talks about how “microbes within a plant’s rhizosphere provide more than just beneficial nutrients for plants”, because bacteria known as Plant Growth-Promoting Rhizobacteria, or PGPR, “serve as a first line of a plant’s defense against pathogenic bacteria, fungi and other parasites” (Bizzell, 2018). This biological activity also contributes to the formation of humus, an organic substance that forms from the partial decomposition of dead plants and animals. By helping accumulate humus, liquid calcium ends up helping the soil become more porous by increasing its ability to retain water and aerate, thereby improving soil structure. 

In a journal article written for the National Library of Medicine, “the mechanisms of PGPR” and their interactions with microorganisms within the rhizosphere and soil have various benefits, including “regulating hormonal and nutritional balance, inducing resistance against plant pathogens, and solubilizing nutrients for easy uptake by plants” (Vejan et al.). Furthermore, the bolstered microbial ecosystem plays a crucial role in helping improve a plant’s resilience against disease, nutrient cycling, and the suppression of harmful pathogens, all of which are essential for healthy plant growth and increased crop yields.

How Does This Impact Production?: ​

Along with leading to better yields and higher crop quality, “the harmful nature of fertilizers and pesticides for the environment has fueled increased interest in the potential use of PGPR as alternatives to these chemicals in agricultural settings” (Rizzell, 2018). This not only has economic benefits for farmers but also contributes to environmental sustainability by reducing chemical runoff and soil degradation. 

Moreover, the ability of liquid calcium to improve soil health and microbial activity underscores the importance of adopting a holistic approach to crop production. By focusing on the biological aspect of soil health, farmers can leverage the natural processes that support plant growth and resilience, paving the way for a more sustainable and productive agricultural system.


The role of liquid calcium in enhancing microbial activity in the soil represents a significant advancement in agricultural science. By fostering a more vibrant microbial ecosystem, liquid calcium improves soil health, enhances nutrient cycling, and supports the overall growth and resilience of crops. As the agricultural industry continues to face challenges related to productivity, sustainability, and environmental impact, innovations such as liquid calcium and the understanding of soil microbiomes offer promising solutions. Embracing these microbial innovations is not just beneficial but essential for the future of crop production and global food security.
