Perlite is a volcanic siliceous rock and is a type of pumice, and when volcanic lava is placed in a cooler atmosphere, water vapor is trapped inside the rock and the molten rock turns into a glass-like structure.

By heating to a very high temperature, the moisture inside the glass is converted to steam, and the perlite is transformed from a dense dark stone into a light, white product. Perlite has an almost neutral pH and is used to reduce soil acidity.

The use of perlite in agriculture prevents excessive soil compaction, improves aeration and uniform distribution of soil nutrients around the plant roots.

Peat Moss:

Peat moss is a type of moss carcass known in English as Sphagnum. The plant grows in humid environments, and as the moss begins to decompose, the wetlands turn into peat moss bushes. Peat mosses have an acceptable capacity to store water and food.

Peat moss is available in dark and light colors in the market and their difference is in the texture of peat moss and the amount of organic mode. The reasons for using this plant are increasing soil organic matter, slightly acidic pH, improving soil porosity, maintaining moisture, sterile culture medium, and all these properties improve the absorption of nutrients, which in turn grows a strong and healthy plant.

Peat moss can be used for greenhouse seedling production, mushroom production, grass planting, vegetable planting, summer crops and flowers, as well as tree planting.
