Understanding Bicarbonate Challenges
Water quality and soil problems are rarely caused by a single issue. In irrigation, agriculture, and industrial watered systems, multiple chemical and biological factors interact at the same time. These interacting factors—what we call water culprits—create scale, soil degradation, reduced nutrient availability, and long-term system damage.
One of the most impactful culprits is bicarbonate, but it does not act alone. Chlorides, sodium, valence-driven reactions, and biological waste products, physical soil conditions, all contribute to water-related challenges. Addressing only one issue will not correct the system as a whole.
HCT approaches water chemistry differently—by solving the underlying reactions, the culprits, that cause long-term damage rather than applying short-term fixes.
Primary Water Culprits Affecting Soil and Plant Health
Bicarbonate
Bicarbonate is a leading cause of scale formation and soil cementation. While it appears harmless when dissolved in water, it becomes problematic as water concentrates and evaporates.
Chloride, Sodium, and Valence
Chloride-related issues are driven by valence, the natural attraction between positively charged ions (cations) and negatively charged ions (anions). Sodium intensifies these reactions, influencing salt bonding, soil structure degradation, and nutrient displacement.
Biological Activity and Waste Products
Microbial activity and biological waste introduce additional compounds into water systems. These factors further complicate water chemistry and cannot be corrected by bicarbonate treatment alone.
Key Point: Solving bicarbonate issues alone does not solve chloride, sodium, or biological challenges. All contributors must be managed together.
How Bicarbonates Create Scale and Hardness
Bicarbonate behaves the same way hard water behaves when it dries on a surface.
-
Water evaporates
-
Calcium and magnesium become concentrated
-
White, hard scale remains
This process occurs throughout irrigation systems, soil profiles, plant surfaces, and infrastructure. Scale formation is not limited to pipes or equipment—it happens in the soil itself.
From Nutrient to Crystal
-
In solution: Calcium and magnesium are beneficial plant nutrients.
-
During evaporation: Bicarbonate enables calcium and magnesium to bond and crystallize.
As water evaporates, calcium and magnesium concentrations increase. Once they complex with bicarbonate, hard crystalline structures form, reducing nutrient availability and damaging soil structure.
Why Acidification Alone Fails
The most common industry approach to bicarbonate control is lowering pH through acid injection.
Short-Term Results
Acidification temporarily breaks calcium-magnesium bicarbonate crystal bonds, producing an immediate visible response.
Long-Term Consequences
Independent research, including studies from UC Davis, has demonstrated that:
-
Once acidified crystals dissolve and water later evaporates again, calcium and magnesium reabsorb bicarbonate,.
-
The minerals reform into denser, more insoluble compounds (such as calcium oxalate).
These compounds:
-
Are highly insoluble
-
Do not break down with additional acid
-
Accumulate in soil over time
-
Cause soil cementation and reduced infiltration
The result is long-term soil degradation—not correction.
The HCT Approach to Bicarbonate Management
HCT does not attempt to remove bicarbonate from water. Instead, we prevent it from bonding with calcium and magnesium.
Chemistry That Prevents Re-Crystallization
HCT developed a proprietary chemical approach that:
-
Breaks apart existing calcium-magnesium bicarbonate crystals
-
Chemically satisfies the electrical charges on calcium and magnesium
-
Prevents these ions from re-complexing with bicarbonate
-
Keeps calcium and magnesium in a stable, ionic state
What This Means in Practice
-
When water evaporates, minerals dry as a fine powder—not a hard crystal
-
When water is reintroduced, nutrients return fully into solution
-
Calcium and magnesium remain ionically available for plant uptake
Benefits of HCT Bicarbonate Control
-
Prevents scale formation
-
Eliminates soil cementation
-
Improves nutrient availability
-
Protects soil structure
-
Restores soil structure
-
Supports plant growth and long-term plant health
-
Reduces dependence on repeated acid applications
Bicarbonate remains present, but its ability to form damaging crystalline structures is neutralized.
Proven Water Chemistry Solutions
HCT focuses on controlling reactions, not masking symptoms. By managing charge balance and ion behavior, we protect water systems, soil health, and nutrient efficiency over the long term. This is how HCT solves bicarbonate-related water problems—by keeping essential minerals small, soluble, and plant-available. WaterSOLV products resolve this conditions to water soluble salts. Crystalline salts are corrected by WaterSOLV Curative and or WaterSOLV pHix.
