Frequently Asked Questions (FAQ)
Spray Water Quality FAQs
Can hard water reduce herbicide effectiveness?
Yes. Minerals such as calcium and magnesium can bind with certain herbicides, reducing their availability for plant uptake. The effect depends on the herbicide, application rate and mineral concentration in your water.

What is the difference between water hardness and water pH?
Water hardness measures dissolved minerals, primarily calcium and magnesium. Water pH measures acidity or alkalinity. These are separate characteristics, so testing pH alone does not tell you whether your spray water is hard.

What pH should my water be when spraying herbicides?
The appropriate pH depends on the herbicide and other products in your tank. Some pesticides perform better in acidic conditions, while others require a higher pH. Follow each product’s label before adjusting spray-water pH.

Is lowering pH enough to fix hard spray water?
Not necessarily. Lowering pH changes water acidity, but does not automatically prevent dissolved calcium and magnesium from interacting with pesticides. Evaluate both hardness and pH when choosing a water conditioner.

How do I test my water before spraying?
Collect a sample from the water source used to fill your sprayer and request testing for pesticide application water. Ask the laboratory about pH, hardness, alkalinity and relevant dissolved minerals. Use the results to evaluate your conditioning needs.

Why are my sprayer screens and nozzles plugging?
Plugging can result from debris, undissolved materials or incompatible tank mixes. Water chemistry can also contribute to precipitation or mineral deposits. Inspect filters, review mixing procedures and check water quality to identify the cause.

How do I check whether my tank mix is compatible?
Perform a jar test using your actual spray water and proportionate amounts of the planned products. Follow label mixing instructions and watch for separation, clumps, gels or sediment. A jar test evaluates physical compatibility; it does not establish crop safety or effectiveness.

Can a liquid water conditioner replace dry AMS?
Whether a liquid conditioner can replace ammonium sulfate depends on the herbicide’s requirements and the conditioner’s functions. AMS can address mineral antagonism and contribute ammonium that enhances activity of some herbicides. Check label requirements before substituting another product.

How do I calculate water conditioner cost per acre?
Multiply the conditioner cost per 100 gallons by your spray volume in gallons per acre, then divide by 100.
For example, a conditioner costing $10 per 100 gallons costs $1 per acre when spraying 10 gallons per acre.
Nuvano Pure FAQs
How does Nuvano Pure act as a water conditioner?
Nuvano Pure utilizes a two step process to condition the water in your tank. Through our proprietary acidification technology we release carbonates and bicarbonates as carboxylic acid and water. Free calcium that is produced through the reaction is then chelated through our proprietary sub-micron chelation technology so that it is unable to react or bind with materials added to the tank.
What is the mechanism of releasing carbonates & bicarbonates in hard water applications?
Nuvano Pure uses an acid-base neutralization that converts carbonates and bicarbonate into carbon dioxide and water.
How does Nuvano Pure do more than my current water conditioner?
Nuvano Pure utilizes sub-micron chelation and lipophilic carrier technologies to help load and transport fertilizers, pesticides and biologicals through the cell membrane and into the plant vascular system.
How do I decide what rate of Nuvano Pure to use in my tank?
Nuvano Pure is designed to be used at 1-2 pints per 100 gallons of water in your tank. The use rate depends on the hardness of your water, level of carbonates and bicarbonates and the starting pH. If you have high carbonates and bicarbonates and/or a higher starting pH, we recommend using the 2 pints/100 gallons. If your water is relatively clean it is appropriate to use the 1 pint or the full 2 pints per 100 to primarily utilize the pH modification and sub-micron carrier technologies in the product to help improve delivery of your tank mixed products.
What products is Nuvano Pure compatible with?
Nuvano Pure is compatible with most liquid fertilizers, pesticides and biological stimulants. As with most water conditioners, it's important to jar test compatibility prior to adding Nuvano Pure to the spray tank.
What is the mixing order when using Nuvano Pure?
Nuvano Pure should be the second product that goes in the tank following water. It will help break down hard water and release carbonates and bicarbonates along with modifying the pH of the water before adding nutrients, biologicals, pesticides and herbicides.
Can Nuvano Pure replace AMS?
Yes, we have replaced AMS on millions of acres. However, it is compatible with AMS if you want to continue using it in your program. AMS will not reduce pH so regardless, you should use Nuvano Pure in your program.
What will Nuvano Pure not replace?
If your product requires a Crop Oil or an Anti-Drift Agent, keep those in the tank with Nuvano Pure.
