PHYSICAL PROPERTIES OF PEAT USED IN HORTICULTURE
- It stores and supplies them with water.
- It aerates their roots
- It stores and supplies the minerals essential to their growth.
The better the substrate performs all these functions, the better it is.
The first two functions — water and oxygen economy — are determined by the physical properties of the substrate, the third function — nutrient economy — by its chemical properties. So in discussing the physical properties of the substrate, we are dealing with the plants' water and oxygen supply.
