3-6mm 4-8mm etc Expanded Vermiculite as growing media?for Agriculture
?
?
?Flakes of raw vermiculite concentrate are micaceous in appearance and contain interlayer water in their structure. When the flakes are heated rapidly at a temperature above 870° C, the water flashes into steam, and the flakes expand into accordion like particles. This process is called exfoliation, or expansion, and the resulting lightweight material is chemically inert, fire resistant, and odorless. In lightweight plaster and concrete
?
?vermiculite provides good thermal insulation. Vermiculite can absorb such liquids as fertilizers, herbicides, and insecticides, which can then be transported as free-flowing solids.

One of the areas of expanded vermiculite is agriculture. In this case, the use of vermiculite due to its porous structure significantly improves the aeration of soil properties and prevents rotting plants germinate;
- The presence of oxides of various metals (magnesium, potassium, aluminum and iron), which makes it ideal biostimulant plant growth;
- Its high water absorption (up to 500%), which allows you to keep an optimum soil moisture regime, even in conditions of prolonged drought.
- According to the results of field tests established that the use of vermiculite allows you to:
- Improve the structure of both light and heavy soils;
- Create the optimal air-water regime of soils;
- Significantly stimulate the growth of plants;
- Reduce the acidity and salinity in the 8-14%;
- Increase the efficiency of fertilizers;
- Reduce root rot;
- Increase safety and productivity of crops by 10-17%
