When it comes to crop nutrition, most farmers are laser-focused on the “big three”: nitrogen (N), phosphorus (P), and potassium (K). These macronutrients are the foundation of nearly every fertility program—and for good reason. They drive plant growth, energy transfer, and structural development.
But while NPK is essential, it’s not the whole story. Crops also depend heavily on hydrogen (H) and oxygen (O)—two elements that often get overlooked in traditional fertility discussions.
Hydrogen
The most abundant element in plants, making up a large percentage of their biomass.
A core building block of carbohydrates, proteins, and oils.
Fuels photosynthesis, helping plants convert sunlight into usable energy.
Plays a role in reducing oxidative stress, which supports plant resilience under droug
ht or heat.
Oxygen
Critical for root respiration and microbial activity in the soil.
Helps plants efficiently absorb and metabolize nutrients.
Supports strong root systems and overall plant vigor.
Enhances soil biology, which leads to better nutrient cycling.
Without adequate hydrogen and oxygen in the root zone, plants may struggle to use the nitrogen, phosphorus, and potassium they’ve already been given. In other words, NPK can’t do its job if hydrogen and oxygen aren’t available in balance.
Forward-thinking growers are beginning to recognize that a truly healthy crop depends on more than just NPK. By ensuring hydrogen and oxygen are present in the soil, farmers can unlock the full potential of their fertility programs.
That’s where Growthful™ from Aqueus comes in. Using patented stabilized hydronium chemistry, Growthful delivers both hydrogen and oxygen directly into the soil, improving nutrient uptake, boosting yields, and supporting long-term soil health.
It’s a simple, powerful way to give crops what they need—not just the big three, but the elements that bring NPK to life.
