Mineral Soil Amendment

Zeolite amended soils show both increased water retention and nutrient utilization. On top of this, zeolite amendments can outperform other amendments by increasing the CEC levels in your soil

Water Retention

sprinklers-on-field-horizontalZeolite has numerous advantages in the area of water conservation and nutrient leaching prevention.

  • Zeolite is capable of holding up to 60% of its weight in water.
  • Tests have shown Zeolite can increase water infiltration by 7%-30% on gentle sloped land and up to 50% on steep sloped land.
  • Soil moisture can be increased by 0.4%-1.8% in drought conditions and 5%-15% in general water situations
  • Consequently, overland surface runoff is reduced, in turn protecting lands from erosion.
  • Use of soluble N fertilizers is a major cause for groundwater contamination. Zeolite reduces nitrate leaching by inhibiting the nitrification of ammonium to nitrate.

Aeration
Zeolites ability to retain moisture is another positive aspect for using Zeolite as a soil amendment. Zeolites can hold up to 60% of their weight in water due to the high porosity of their crystalline structure. Zeolite acts as a non-form changing, permanent water reservoir which provides prolonged moisture during dry periods as well as promoting rapid re-wetting and improved lateral spread in the root zone during irrigation. This in turn reduces the quantities of water needed for irrigation.

The porous structure of natural zeolite also helps to keep the soil well aerated. Unlike other soil amendments such as lime and clay, Zeolite does not break down over time, but remains in the soil to improve nutrient and water retention which can significantly reduce costs of water and fertilizers over time (Demir H, 1993). Zeolites porous structure will not clog soil pores over time like clay will.

Arsenic
Crops watered with knowingly or unknowingly arsenic contaminated groundwater can lead to uptake into edible crops, eventually finding its way up the food chain. Zeolite’s affinity to arsenic allows it to capture and hold heavy metals and select toxins such as arsenic, the plant will not exchange for them if given the choice. When in free form, the plant has no other option but to take up heavy metals.

Common Course Problems

Turf-grass root zone materials are generally chosen for good drainage, resistance to compaction, and good aeration. This mixture is prone to low cation exchange capacity along with low water holding capacity (Petrovic, 1993).
Alongside organic matter such as peat or composts, Clinoptilolite Zeolite will improve the CEC of soils, increase efficiency of water uptake, and increase nutrient utilization. All while reducing nitrate leaching (Petrovic) and staying in your soils year after year due to the characteristics of the mineral.

Dry Peaks and Flooded Valleys
The general physical makeup of peaks and valleys on any green or fairway can cause water to runoff slopes and pool in valleys. Specialized watering schedules can help, but will only minimize the problem, wasting valuable resources.

Nutrient Runoff and Leaching
The use of water soluble-fertilizers to add-in Nitrogen, Potassium, and Phosphorus to turf can have a low efficiency rating and runoff when spread onto unamended sand-based soils.

Zeolite enhances the performance of fertilizers by making them resistant to leaching, immobilization, and gaseous losses. They are particularly useful in reducing leaching in sandy soils by increasing the CEC values and decreasing volatilization.
Zeolite itself carries small amounts of plant nutrients. Their use as inorganic amendments stems primarily from their high nutrient-exchange capacities, which allow them to absorb and release plant available nutrients and moisture without changing or breaking down the structure of the Zeolite. This absorption/adsorption allows Zeolite to hold nutrients in its structure which acts as a slow release fertilizer to exchange nutrients with turf as needed, increasing fertilizer efficiency. This is especially important during turf establishment or heavy rainfall which can increase leaching to 10x normal (Shaddox, 2003) especially in low CEC sand based soils.

Once entered into soil either through a mixture of organic material such as compost or top-dressed after aeration, Zeolite will work its way down into the root zone and proceed to provide benefit year after year, while still draining after compaction because of its porous structure.

Turf Maintenance

A BMP study done by Cornell University in 2014 speaks on water infiltration rates that are dependent on soil makeup and texture. Sandy soils tend to have a high porosity and greater infiltration rates which affect root zone depth and watering frequencies. Because of this, amendments are often needed to increase nutrient and water holding capacity (NYUgolf.edu). Preferential flow and compaction restrictions can lead to dry spots or saturated areas that Zeolite can help amend and work the water flow toward the more desirable matrix pattern.

Infiltration
Most turfs are constructed using a sand substrate that promotes rapid water infiltration and high air porosity. Zeolite acts similarly in terms of air porosity while increases infiltration. In 2007, the USGA released a summary of root zone amendments showing the downsides and lack of root zone maturity to non-amended sandy soils.
