Perlite Benefits in Agriculture and Horticulture
Perlite offers wide range of benefits in agriculture and horticulture, boosting plant growth and soil health:
- Heat Protection: works as an insulator; therefore, it protects the plants by reducing high temperatures and making plant's roots less affected by climate change.
- Aeration: Provides room for air and water, preventing over-watering and allowing proper drainage. Enhances soil aeration, crucial for preventing soil compaction and promoting healthy root growth.
- Water Holding Capacity: Has the ability to hold water up to +600% of its weight, releasing it slowly to plant roots as needed, extending the time between irrigation and reduce water and compost consumption.
- Neutral pH: With its neutral pH (6.5 to 7.5), making it ideal zone for most plants to absorb nutrients. Perlite does not alter the acidity of the soil, making it suitable for a wide range of plants.
- Pest and Pathogen Resistance: Perlite is sterile and does not support the growth of fungi, root rot, or gnats, contributing to healthier plants.
- Lightweight: The lightweight nature of perlite makes it easy to handle and reduces the load on structures when used in rooftop gardens or vertical farming.
- Inorganic mineral: Perlite is not subject to change and does not degrade
- Clean and convenient mineral: does not produce unpleasant odors, in addition to being lightweight and easy to use, which makes the process of soil treatment and tillage easy and economical for farms.
- Enhanced Plant Health: Perlite's structure facilitates root oxygenation and penetration and access to nutrients, which promotes vigorous plant growth and leads to stronger, healthier plants capable of withstanding various environmental stresses.
Perlite's use in agriculture and horticulture is revolutionary, addressing the essential needs of modern sustainable farming and gardening. The science behind perlite's success in these fields lies in its physical structure, formed when volcanic glass is heated to a high temperature, causing the water content to vaporize and the material to expand. The primary role of expanded perlite in soilless growing mixes is aeration when added to peat moss, composts, coir and other water-holding aggregates. The porous surface of perlite provides room alternately for both air and water in the mixes each needed for vigorous root growth.
Perlite is a heat expanded, man made Perlite for use as a hydroponic growing medium. Perlite retains enough moisture for it to be suitable as a hand watered medium, but also has sufficient drainage to be used in a recycling drip irrigation system. Perlite is extremely lightweight and is suitable for use in a variety of growing containers pots, trays, bottom fed auto watering systems, etc.
---Expanded Perlite Application:
* Horticultural Applications
In horticultural applications, perlite is used throughout the world as a componet of soilless growing mixed where it provides aeration and optimum moisture retention for superior plant growth. Other horticultural applications for perlite are as a carrier for fertilizer, herbicides and pesticides and for peletizing seed.
* Construction Applications
Perlite is widely used as a loose fill insulation in masonry construction. Other construction applications include chimney linings, under-floor insulation, gypsum boards, paint texturing, ceiling tiles, and roof insulation boards etc.
* Industrial Application
Ranging from high performance fillers for plastics to cements for petroleum,water and geothermal wells
