What is pHirst?

pHirst is a urea-sulfuric acid adduct that is produced under a unique process. The end product is a high quality, clear liquid material. A corrosion inhibitor for metal is added during the manufacturing process.

Our Difference

So, what’s the difference between pHirst and some other products produced by some other producer.

First of all, pHirst is produced with only the best raw materials. Without the finest raw materials, the production method is immaterial. The sulphuric acid used in the production of pHirst is a “virgin” acid. This simply means that it has not been used in any industrial process that contributes to the addition of “heavy metals”. Not only is the acid virgin, it also meets U.S. standards for “heavy metals” content.

Quality urea is the other essential ingredient in pHirst. In handling urea, foreign materials such as gravel and other debris can find their way into the urea. Our urea is handled with the utmost of care. If any question arise about foreign material mixing with our urea, then the end product (pHirst) is filtered through an expensive set of filters. This ensures that when the product is delivered to the golf course, it will not clog any of the irrigation systems (including the low volume systems).

No other production company has this quality control measure in place.

A corrosion inhibitor is also added to pHirst. This helps reduce corrosion where pHirst comes into contact with metal in delivery tankers and bulk storage tanks.

Do you need pHirst?

Most irrigation water contains some amount of dissolved salts. Some are beneficial and some can be toxic.

The Beneficial: Beneficial salts such as calcium, magnesium, nitrate, and sulfate are free beneficial nutrients.

The Toxic: Other salts are also present such as sodium, chloride, and boron that must be carefully managed or avoided if possible. A third group that interacts with and is usually present with these salts consists of carbonates, bi-carbonates, and silicates.

Along with all of this, high pH can compound the problem. In addition, liquid phosphate materials can also form insoluble precipitates with the carbonates and bicarbonates that can reduce fertilizer efficiency. The presence of these salts in irrigation water can cause soil structure to break down.

The Answer: Add pHirst water treatment to your irrigation program. This reduces bicarbonates in your irrigation water. Destruction of bicarbonates has to happen before sodium will move down through the soil profile below the root zone where damage occurs.

Acidulating the irrigation water produces calcium improving soil structure and aiding water penetration increasing the availability of phosphorus, micronutrients and frees up nutrients that are unavailable to the plant in alkaline conditions. When undesirable cations (sodium, etc.) are flushed through the soil profile the are replaced with beneficial cations such as calcium.
