Decomposition of hydrophobic (or water repelling) waxy materials originating from plant residues can coat soil particles preventing the infiltration of water into the soil profile (figure 1; Van Gool & Moore, 1999). Then I add a good 10cm layer of home made compost on top and use the mulch hay to cover the soil.

It should wet the soil surface immediately. How to Fix Hydrophobic Soil. Initially there will be so much air in the root ball that the pot will float. Healthy soil with a balanced and diverse microbial population doesn’t tend to get hydrophobic. Characteristics of a degraded soil include: high salinity, decline in fertility, decline in organic matter (leading to decline in soil structure), soil … Obviously, all soils aren't the same.

The reason that hydrophobic soil loses its water retention properties is because it lacks organic ingredients – the parts of it that were once living things. How can I fix hydrophobic soil? In contrast when you wet soil that is not hydrophobic, the water is quickly absorbed," he said. Estimated losses for crop and pasture production due to water repellent soils exceed $100M. If a droplet of water beads up on the surface and does not penetrate a soil surface after 5 seconds, the soil can be characterized as hydrophobic (see below). Another cause of hydrophobic soil is when there is too much peat moss in the pot. Peat moss is a fantastic material but if it is left to dry out it can then cause a mixture to become hydrophobic.
