Zeolite for Soil Conditioning  

Zeolite based fertilizers are known to be "intelligent fertilizers" due to their high cation exchange capacity and porosity.
Recall, Zeolite is the worlds only negatively-charged mineral in existence, it therefore has tremendous breakthrough
possibilities and especially in Agriculture applications. Zeolite has a proven ability of a natural slow release mechanism of
nutrients to the root zone of new seedling thereby increasing the plants' strength and performance. Zeolite also provides
the following attributes for agriculture applications which lead to improvements to overall crop yield:
• Captures and regulates the release of nutrients (compost and fertilizer) to the soil,
• Absorbs and traps toxic contaminants,
• Provides buffering capacity by balancing soil pH,
• Reduces alkalinity effects,
• Improves aeration,
• Provides an excellent platform for microbiological activity,
• Promotes alkali metal equilibrium,
• Improved root development
• Retains moisture,
• 100% natural for organic farming operations,
• Breaks down clay clumping, and
• Promotes germination and the sustained growth of grasses and grains.
All of these processes establish a stronger seedling thereby reducing the need to apply pesticides. Many studies have
shown that Zeolite enhancement in contaminated soils promotes healthy germination and growth that even exceeds
growth in the uncontaminated control soil. Zeolite contains no inherent nutrient value and is 100% organic. The only
processing is simply sizing in order to suit your mesh requirements. Nutrients are provided to the root in a slow-release
and plant root demand-driven fashion. The process is a combination of dissolution and ion exchange reactions. The
absorption of nutrients from the soil solution by plant roots drives the dissolution and ion exchange reactions, pulling
away nutrients as needed. The Zeolite is then "recharged" by the addition of more dissolved nutrients. Zeoponic systems
increase nutrient retention, reduce environmental nutrient losses and reduce fertilizer requirements by establishing a
replenish able and balanced nutrient supply in the plant root zone.
Zeolite improves soil structure by coupling high cation exchange capacity (CEC) with a selective affinity for ammonium
and potassium. Zeolite is very porous with an incredibly large surface area. The selectivity of Zeolite for ammonium helps
buffer the soil and prevents toxicity, which occurs when excess ammonium is applied. This property allows the grower to
use this less costly form of nitrogen in larger and less frequent applications during the growing season. The retention and
timely release of needed nutrients by Zeolite improves overall crop yield. It provides a lasting reservoir of nutrients
allowing the user to reduce added fertilization while achieving better plant and vegetable performance. There is an
environmental bonus from the product as well. Unlike commonly used fertilizers, the plant-growth material dramatically
reduces loss of nutrients to groundwater and the environment.
Increased utilization of manure and biosolids as a rich source of nutrients is gaining popularity. As application rates
increase there is a concern about the additive effects of toxic components. Salt and heavy metals are the main problems,
although fugitive losses of ammonia to atmosphere and nitrogen and phosphate loss to groundwater are also a concern.
Zeolite's hold nitrogen in the soil, moderate nitrification of ammonia and make it available to plants as needed
Zeolite is simply applied at a rate of only 5 to 10% (by weight) along with your current fertilizer (ie: simply replace 5 to
10% of your fertilizer with Zeolite). The cost of Zeolite is less than your current fertilizer and therefore it does not add to
your bottom line input cost/acre.
For top dressing, approximately 30 to 60 pounds should be applied per 1,000 square feet
or 1,200 to 2,500 pounds per acre. To enhance aerification after plugging, apply 60 to 150 pounds
per 1,000 square feet or 2,500 to 6,500 pounds per acre. For crops and grasses successful improvements have been realized
with as little as 1 ton per acre. Generally, 2 to 10 tons per acre are applied depending on the composition of the soil being
treated. Zeolite can be spread by hand broadcasting, using a manure spreader, or by other devices. Although top dressing
works, generally  
it is better to mix the Zeolite in the top 2 to 4 inches with a rototiller, spike tooth harrow, or a disc harrow. Plowing
Zeolite in, places it deeper than necessary. For row crops such as corn or
soybeans, Zeolite can be applied with a side disc or by side banding. After application, the area
must be irrigated, because fresh Zeolite will absorb moisture from the surrounding soil and can
result in dehydration of the plants or grasses.
