• Loosens the density of heavy soils, letting in the air and water plants need.
• Increases water retention in light and sandy soils.
• Reduces crusting, cracking, flooding and shrinking & swelling of clay soils.
• Holds moisture in the soil, reducing watering requirements by as much as 35%, but pumice will not compact or become soggy.
• Is inorganic, so it will not decompose or compact over time, meaning it functions continuously and can be recycled and reused.
