Perlite is a kind of irregular, amorphous and amorphous volcanic rock with the chemical formula of SiO2, which has a lot of water in its structure. Aluminum, sodium, calcium, potassium, manganese and iron are other elements that make up perlite. There are different mines of this material all over the world
Perlite use
The most important benefits of using perlite in agriculture and gardening are in short:
1- Improving the soil aeration and watering system
Perlite has a very low density and its combination to the soil, especially heavy textured soils, helps to lighten the soil texture and thus increases The porosity of the soil and, as a result, the ventilation and drainage of the soil will be improved. absorb it on its surface and gradually release it to the roots of the plant. As a result, using it in all kinds of potting soil helps to improve the nutritional status of the plant and saves on the consumption of fertilizer and nutrient solution in horticulture and agriculture. 3- Neutral pH and no disturbance in natural growth. Plant
Perlite has a neutral pH (6.5-7.5) and is insoluble in most natural environments. Therefore, it does not cause a significant change in the alkalinity or acidity of the culture medium and does not have any problems for the growth of plants. In addition, adding perlite to the soil and hydroponic planting beds balances the acidic or alkaline pH of the growing bed. In the range of this pH, the absorption of nutrients is maximized, and as a result, the nutritional status of the plant is also improved.
4. Absence of sudden changes in soil temperature
Because it is a heat insulator, perlite prevents soil temperature fluctuations and is therefore effective in controlling the frostbite of plant roots.
5. Prevention of the negative effects of weeds and harmful insects
Perlite soil is free from any pests and pathogens and has properties similar to herbicides.
6. Non-disruption of soil structure
The chemical formula of perlite is silicon oxide, which is the main ingredient of soil and has a composition similar to the chemical composition of soil ingredients. Therefore, adding it to the soil has not changed the characteristics of the soil and does not harm the environment.
By adding perlite to the soil, economic efficiency and agricultural performance will increase. All experts in this field are aware that improving soil properties is one of the most expensive parts of agriculture, and using perlite helps to reduce these costs. Also, unlike organic materials, perlite will not rot and will maintain its positive properties in the soil for a long time.
