Isolite is a porous ceramic consisting of up to 74% pore space. It conserves water, decreases compaction, increases soil surface resiliency, and favorably affects total soil porosity and oxygen levels. Isolite has a positive effect on microbial activity, soil moisture content, soil permeability, nutrient retention, and healthy root growth. It holds water against evaporative and gravitational loss and increases plant-available moisture and oxygen in the root zone, reducing irrigation requirements and promoting the production of healthy root tissue, thereby making it an ideal soil amendment.
Isolite is a permanent soil amendment. In sandy-type soils, it holds and makes water available to plants; while in clay-type soils, Isolite opens up the soil and allows for better percolation rate. It is a one-time application. Many other product representatives will often tell you their product is cheaper than Isolite, but often fail to tell you that their application rate is three times as high. Isolite is diatomaceous earth-based compared to many other products that are clay-based. The majority of the pores in any product for soil amending should be larger than 1 micron. If the pores are smaller than this number, microbes will not be able to get into them and water release will be difficult.
Isolite is produced from diatomaceous earth, formed in uniform granules with proprietary combustion, resulting in a porous ceramic consisting of up to 74% pore space. Isolite is an extremely stable porous ceramic that will not break down or migrate in the soil and can be used as a soil amendment that increases percolation rate in tight soils, and increases water holding capabilities in sandy soils. The significant internal pore space makes a perfect condominium for beneficial microbes to live and thrive and will reduce the growth of pathogens in soils. This condominium effect for bacteria is an ideal support matrix for bioremediation.
Isolite can be used for the bioremediation of soil and water. Because of the uniform size, the interconnected pores, the optimum internal pore distribution for bacteria, the water-holding capacity, and the ceramic characteristics, Isolite makes a perfect matrix for the immobilization of microbes that can reduce pollutants in the soil without having to use expensive and outdated hauling or “pump and treat” technologies.
Specifically for bioremediation, microbes require pore space diameter greater than .5 (micron) in which to live. Most of Isolite's pore space diameter is between 1 and 4 microns. Most other porous ceramics have pores that are less than .5 micron. The Isolite is the "condominium" for the microbes and the pollutant is the food. Isolite creates a good environment for the biological breakdown of pollutants into elemental (simplest) forms.
