PrimAgro C-Tech
Bacillus Subtilis Fertilizer
PrimAgro C-Tech®
Advanced Carbon & Biological Soil Enhancement in a Single Package
For any producer wanting to improve the microbial activity in their soil, provide the microbiome with an additional carbon food source, and provide fulvic acid for their crop, AgroLiquid’s PrimAgro C-Tech® is a single package that combines fulvic acid, carbon, and Bacillus subtilis and Bacillus amyloliqufaciens in a single, easy-to-use product that can be applied to a wide range of crops at planting, sidedress, foliar or through irrigation.
Key Ingredients and Benefits
Fulvic Acid
- Functions as a potent soil conditioner, similar to humic acid but more biologically active due to its high oxygen content.
- Enhances nutrient availability by binding and transporting essential elements into plant cells for increased uptake.
- Serves as a carbon food source for both Bacillus species within PrimAgro C-Tech.
Bacillus Subtilis
- Primes the plant immune system by triggering induced systemic resistance (ISR) to help crops defend against pathogens.
- Fixes nitrogen and solubilizes phosphorus, improving nutrient availability and promoting nodulation.
- Produces natural plant-growth hormones—cytokinins, gibberellins, auxins—plus organic acids and siderophores to boost root and shoot development.
Bacillus Amyloliquefaciens
- Also triggers ISR, reinforcing plant defenses.
- Fixes nitrogen and solubilizes both organic and inorganic phosphate for enhanced nutrient uptake.
How PrimAgro C-Tech Works
PrimAgro C-Tech is a Bacillus species-containing fertilizer that combines organic acids and live strains of bacteria. It is designed to optimize nutrient uptake and metabolism, and prevent nutrient loss through leaching.
PrimAgro C-Tech combines microbes with AgroLiquid’s proprietary formulation technology to provide a healthy environment to stimulate plant growth and health.
C-Tech has been recognized by The Fertilizer Institute as a Certified Biostimulant. This certification affirms AgroLiquid’s adherence to industry-recognized standards for efficacy, safety, and composition of PrimAgro C-Tech.
PrimAgro C-Tech may be applied by itself, or combined with a variety of other fertilizer products. Flexible application methods make this product easy to apply without requiring extra time or energy.
Product Benefits
- Restores beneficial soil bacteria
- Promotes retention of plant-usable nutrients in the soil
- Improves the soil nutrient profile
- Improves soil health
PrimAgro C-Tech may be used by itself, or with other fertilizer products to improve soil health. PrimAgro C-Tech uses carbon and biological agents intended to improve the nutrient balance and nutrient uptake ability of plants.

Have us design a custom nutrition plan for you
An AgroLiquid nutrition plan is dependent on your location, climate, soil conditions, and goals with your crop. All of our tailored programs start with reviewing your soil samples with one of our expert agronomists. After our analysis, our team will provide you with a couple options that will help you meet your goals on a budget that won’t break the bank.
AgroLiquid Scientific Advancements
PrimAgro C-Tech may be applied to any growing crop or active soil to promote microbial activity, and plant and soil health. By restoring microbial activity and the natural decomposition processes within the soil, nutrients become more available and usable.
Nutriq Technology
This bonds with your nutrients and creates a protective layer that makes up to 80% more of your nutrients available to plants. It sounds like magic, but it’s just science.
Have a specific crop problem you’re trying to solve?
AgroLiquid was founded because there wasn’t a nutritional product that was solving our fertilizer needs; after 35 years of development and research, our chemists, biologists, and agronomists continue to innovate and create the best products on the market. If you have a specific crop problem, ask one of our agronomists and we’ll help you solve it!
