CLINOPTILOLITE FOR GOLF, LAWNS AND GARDENS
For the construction of new golf course greens and tees, lawns, gardens, or for sandy soils replace 10 to 20 % of the sand with an equal volume of Clinoptilolite. This should be applied in the top 2 to 4 inches. 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. Clinoptilolite can be spread by hand broadcasting, using a manure spreader, or by other devices. Although top dressing works, generally it is better to till the Clinoptilolite in the top 2 to 4 inches with a rototiller, spike tooth harrow, or a disc harrow. Plowing Clinoptilolite in, places it deeper than necessary. For row crops such as corn or soybeans, Clinoptilolite can be applied with a side disc or by side banding. After application the area must be irrigated and fertilized, because fresh Clinoptilolite will absorb moisture and nutrients from the surrounding soil and can result in dehydration and nutrient starvation of the plants or grasses until an equilibrium has been reached.
It has a higher cation exchange capacity for ammonium than any natural clinoptilolite commercially available in the western U.S. This quality favors greater retention of ammonium (NH4+) when the turf or soil is fertilized with highly soluble ammonium-based fertilizers.
- This product contains only clinoptilolite that is commercially produced by Incal Mineral.
- It has a high surface area (pore space) of about 25 m2/gram (as measured quantitatively by gas adsorption). This property allows a high capacity for water retention inside the granules, and also provides space for soil aeration.
- When mixed with animal or poultry manure this product provides a temporary storage for ammonium and will reduce the odor of the manures.
- The low concentration of exchangeable sodium avoids potentially plant toxic sodium accumulation in soil.
- Moderate physical strength and lack of clay minerals and high pore space and permeability provides a material which promotes aeration in soil, whereas other clinoptilolite with low physical strength and layer silicates such as clay minerals tend to pack and thereby reduce aeration and also provide physical barriers to water movement in the soil.
- The low concentrations of potentially toxic trace elements comply with State and Federal regulations regarding the amounts of these in materials contained in fertilizer and soil amendment products.
