Description of Maxand Particle
A Maxand particle is a polymeric and ion exchange complex created by permanently coating USGA spec sand. The following is a more detailed description of the ingredients used to create the Maxand Particle graphically depicted above.
- MPEG (methoxypolyethylene glycol): MPEG, a commonly used water-loving component used in surfactant synthesis, is an integral ingredient in the Maxand polymer. With MPEG permanently tethered to the surface, the Maxand particle is a solid-state wetting agent. The Maxand particle helps to manage moisture, providing uniform wetting of the root zone and thereby reducing or eliminating Localized Dry Spots. The MPEG molecules covering the Maxand surface will not retain sodium. The Maxand particle excludes sodium from the moisture on its surface, thereby providing a reservoir of fresh water to the plant (depicted on the graphic as a “halo effect” around the Maxand particle). With the sodium expelled into the large pore space between particles, flushing of salts should be made easier.The Maxand polymer retains many classes of environmentally persistent but mobile but pesticides in a plant available form. Pesticides are more uniformly distributed and held longer in the root zone. The result is improved efficacy of the most commonly used pesticides.
- Calcium Bentonite Clay: Clay is permanently attached to the surface of the particle. The clay possesses Cation Exchange Sites. The Cation Exchange Sites efficiently store and release nutrients such as ammonium, potassium, iron, manganese, calcium, magnesium and copper. The Nutrient Retention section shows Maxand’s ability to retain plant essential nutrients in a USGA spec green constructed with Maxand incorporated into the rootzone at a 20% blend rate.
- Anion Exchange Sites: The pigment that is used to color the Maxand particle possesses Anion Exchange Sites. These sites efficiently store and release Phosphorus in the form of phosphates in addition to other nutrient anions. These sites are permanently cured on the particle surface. Results provided on Table 1 of the Nutrient Retention section shows Phosphorus retained in the Maxand-amended soil at a rate over 43% higher than the control plot of a commonly used 90/10 sand/peat mix.
