Dryness, plant chemicals, aromatic oils, and other chemicals also cause hydrophobicity. A thin layer of soil at or below the mineral soil surface can become hydrophobic after intense heating. The hydrophobic hydrocarbons are repelled by water but are attracted to oil and grease. To wet hydrophobic soils, add several drops of liquid dish-washing soap to a watering can filled with water and slowly apply to the soil. Soils that contain large amounts of sand or that contain large amounts of organic matter tend to be hydrophobic. Copyright © 2020 Education.com, Inc, a division of IXL Learning • All Rights Reserved.

The definition of “hydrophobic” can easily be gleaned from its Greek roots; hydro (meaning water) and phobia (meaning fear, or hate). What could we do to improve Education.com? Repeat this test for the two other detergent solutions. They may also interfere with the life-cycles of some aquatic organisms. Evaluate your hypothesis in light of your observations. The goal is to have the student formulate and test a hypothesis about the feasibility of using a washing detergent as a wetting agent for soils that resist penetration by water. Just keep in mind that poorly decomposed organic matter such as leaf litter can release waxy residue that can build up and make soil water repellant . These impact on the waxy residues in the same way washing detergents impact grease … I’ve come across this problem when starting a garden in a previously uncultivated area.

In this experiment you will use plastic and magnets to test your local soil composition. In high concentrations they may be poisonous. The upper few inches of soil are often hydrophilic. In the long run, adding more organic matter should be your goal. Wetting agents reduce the surface tension of water, allowing it to spread on the waxy surface coating soil particles and into the pores in the soil.
