What is pHirst™?
pHirst™ is a urea-sulfuric acid adduct that is produced under a unique and closely supervised precise process. The finished product is a highly versatile material used to treat and control pH, bicarbonates, Zebra Mussels and scaling. A corrosion inhibitor is added during the manufacturing process to prevent damage to containers for shipping and transportation purposes.
So what is the difference between Our Product and others? pHirst™ is superior due to the fact that we only use the finest raw materials
available. Without premium raw ingredients, the production method is immaterial. The sulfuric acid used in the production of pHirst™ is a “virgin” acid. This simply means that it
has not been used in any other industrial process that contributes to the addition of heavy metals or referred to as “Spent Materials”.
Quality urea is the other essential ingredient in pHirst™. If improperly handled, foreign materials such as gravel and other debris can find their way into the production process. Our urea is handled with strict quality control and a multifaceted filtration system to produce the finest product available. We guarantee that our product will not clog irrigation systems whether they are high or low volume.
Do you need pHirst™?
Most irrigation water contains some amounts of dissolved salts. Some are beneficial and some can be toxic.
What is Beneficial?
Salts such as calcium, magnesium, nitrates, and sulfates are free beneficial nutrients.
What is Toxic?
Salts that are present such as sodium, chloride and boron must be carefully managed or avoided if all possible. A third group that interacts with and is usually present with these salts are of carbonates, bicarbonates and silicates.
If left untreated, high pH compounds 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 also causes soil structure to breakdown.
What is the Answer?
Add pHirst™ water amendment to your irrigation program to reduce bicarbonates in your irrigation water. The destruction of bicarbonates must happen before sodium will leach through the
soil profile and root-zone otherwise damage occurs from the buildup of salts. The acidulation of irrigation water produces calcium that improves soil structure and aids in water percolation.
This process increases the availability of both nutrients and micronutrients that are otherwise would be unavailable to the plant in alkaline conditions. When undesirable cations such as sodium are flushed through the soil profile, they are replaced with beneficial cations such as calcium that create pore space and beneficial soil structure.
