Abstract:

A naturally occurring zeolite is coated with a special nanophase Fe oxide, thereby forming a nanophase Fe oxide coated zeolite. The composition thus formed can be used for a variety of horticultural and floricultural end applications. When the nanophase Fe oxide coated zeolite is dosed with plant nutrients and is then mixed with a suitable potting compound, the result is a Complete Plant Growth Medium (CPGM). Blending 5% to 25% CPGM by weight with sand, peat, compost, vegetable and flower beds, and native and manufactured soils, provides a number of beneficial properties. Also, CPGM alone can be used for growing indoor plants to avoid plant pests and compost odor.
