Greensmiths, Inc. pHairway® Water Treatment Amendment is a turfgrass management tool that lowers alkalinity and improves water penetration. By releasing nutrients tied up by high pH soils, pHairway® increases fertilizer performance. It also increases the effectiveness of alkaline sensitive pesticides, and improves soil quality.
pHairway® is 100% MCDS (Monocarbamide dihydrogen sulfate). pHairway® is a safe, non-regulated, non-hazardous material. Guaranteed for golf course irrigation systems, it is the only amendment that offers such a warranty. Its unique chemistry consists of an acid group and a base group held together by an oxygen molecule. The breakdown of pHairway® allows for the release of free oxygen into the water and soil thus reducing the incidence of Black Layer.
Injecting pHairway®
The injection of pHairway® into the water source starts a complex series of reactions. First, with the contained minerals in the water source and then with the soil, where the treated water is applied. The wrong kinds of dissolved salts are often the source of issues in water sources and soil. Separately, we will address cases where the water contains too few salts.
A Water Profile
In The Water: As pHairway® is diluted after injection, the contained acidity reacts with the minerals in the water primarily the bicarbonates. It is important to understand that of all the mineral constituents (dissolved salts), bicarbonates are usually the most important, in terms of their potential for damaging the irrigation equipment, soil and plants being watered. This is because bicarbonates react with other contained minerals, especially calcium, to form insoluble salts, specifically limestone (CaCO3). This causes several problems:
- It causes a white precipitate to form on irrigation equipment, which can lead to corrosion and plugging.
- This white precipitate leaves a white residue on plants and structures (fences, buildings, etc.).
- Bicarbonates remove soluble calcium from the water, which is needed to maintain open soil pore spaces and good long-term soil structure and water penetration.
Some of the active ingredients in pHairway® react with the bicarbonates in the water and produce harmless constituents-carbon dioxide and water. This reduces the potential for forming lime deposits. In place of the bicarbonates and lime, the water becomes a diluted solution of calcium sulfate or gypsum. Gypsum is a well-known soil amendment.
A Soil Profile
In The Soil: As the pHairway® treated water reaches the soil, several additional reactions take place. The diluted solution of calcium sulfate (gypsum) will increase the soil aggregation. This happens when soluble calcium reacts with soil particle surfaces, causing them to release unwanted salts such as sodium, while acting as a chemical adhesive to build soil structure. This produces several related benefits:
- High pH or alkalinity is a sign of Sodium. Alkalinity is undesirable because it causes many of the necessary soil contained nutrient minerals to be unavailable for plant uptake and use.
- Sodium causes soil particles to breakdown. This physical breakdown of the soil structure prevents water penetration and proper aeration. Accordingly, the plant roots do not get enough water or enough oxygen, and the accumulated salts do not get leached down and out of the root zone.
- At the same time, much of the applied water runs off because it cannot penetrate the soil. The addition of pHairway@ can solve these problems by providing soluble calcium to reform or maintain the soil structure for good water penetration and aeration, while removing the sodium and the associated alkalinity and excess salts.
- Additional ingredients in pHairway® act as a timed-release source of acidity. The availability of this acidity is dependent upon the rate of biological processes in the soil. The release of the “in place” acidity is important in inhibiting the formation of alkali layers below the soil surface, and maintaining readily available mineral nutrients. pHairway®’s ingredients are all utilized as nutrients by the plant.
