Why Growers Are Replacing AMS with Growthful: A Smarter Approach to Irrigation Water and Soil Chemistry

by | Apr 9, 2026

For decades, ammonium sulfate (AMS) has been a go-to tool for growers looking to manage water pH and improve nutrient availability. It’s familiar, widely used, and often considered essential in spray programs. But today, more growers are asking a simple question: Is there a better way?

The Problem with AMS

AMS works by forcing pH down through salts. While this can help acidify water, it comes with trade-offs that are often overlooked. As shown in the comparison, AMS:

  • Adds unnecessary nitrogen and sulfur regardless of need
  • Increases salt load in soil and spray solutions
  • Can contribute to buildup that impacts soil structure and root function over time
  • Does not improve how water or nutrients move through the plant
  • Can form sulfate gels that plug sprayer lines, screens, and nozzles

At the same time, water quality plays a critical role in how well inputs perform. Research has shown that when spray water is too alkaline, products can degrade rapidly, sometimes reducing effectiveness from hours to minutes.

A Different Approach: Buffering, Not Forcing

Growthful takes a fundamentally different approach. Instead of forcing pH down with salts, Growthful buffers water into a more optimal, plant-friendly range using hydrogen-based chemistry that donates H+ protons to the water environment. When added to water, Growthful supports the formation of carbonic acid (H₂CO₃) from dissolved CO₂, creating:

  • A more stable, buffered pH
  • Improved nutrient solubility
  • A balanced solution for plant uptake

This means fewer drastic swings and more consistent performance across your entire program.

Extending the Life of Your Inputs

One of the most immediate impacts growers see is in spray performance. By buffering pH into an optimal range, this process helps extend the half-life of herbicides, fungicides, and insecticides in solution.

The result:

  • More consistent efficacy
  • Better uptake
  • Greater return on every pass

Instead of breaking down quickly in alkaline water, inputs remain active longer, giving them time to work as intended.

Beyond Water: Improving Soil and Plant Performance

Growthful doesn’t stop at water conditioning. Compared to AMS, Growthful also:

  • Reduces nitrogen loss from leaching and denitrification
  • Supports carbonic acid generation in soil
  • Improves water and nutrient movement within the plant
  • Enhances root development and biological activity
  • Buffers pH over time rather than continually acidifying

Rather than only buffering the pH of your water, it has the potential to improve the entire system.

Cleaner, Easier, More Efficient

Another key advantage is simplicity.

Growthful is:

  • Safer and easier to handle
  • Easy to integrate into existing programs
  • Free from the salt load and buildup associated with AMS

It also helps prevent gelling and clogging in spray systems, keeping equipment running smoothly and reducing downtime.

Why Growers Are Making the Switch

At its core, the shift away from AMS comes down to this. Growers need lower pH in their water to unlock nutrients in their soil, and they need better performance from that soil to grow substantial, healthy crops.

Growthful’s hydrogen delivers:

  • More stable chemistry
  • More efficient inputs
  • A more reliable system overall

A Smarter Path Forward

AMS was designed for a different era of agriculture. Today’s growers are managing more complex systems: biologicals, precision inputs, and tighter margins. That requires a new approach. Growthful is a safer, more efficient alternative to more than just AMS. It’s an upgrade to how water, nutrients, and inputs communicate and work together for your crops.
