The purpose of a soil wetting agent is to overcome water repellency in soils. This is where the soil actually becomes hydrophobic. Instead of water sinking into the soil, it beads on the surface without penetrating. Soils can become hydrophobic if they are dry for long periods of time or if they are naturally sandy. See more The soils most likely to be affected are sandy soils, soils that are rich in organic matter and also potting mixes. If you mulch extensively this may also cause microbes to grow in … See more To see if your soil is hydrophobic, there is a simple test that you can do. Take some dry soil and place it in a container. Make a well in the soil and then pour water into the well. If your soil is … See more Soil wetting agents are available in both liquid and granular forms. The granular forms are great for potting mixes and they work by putting the wetting agent into small granules of clay or another organic material. The wetting … See more Most soil wetting agents are alcohol or petroleum based, and work by reducing the surface tension of water, which helps it to penetrate into the soil. These are not classed as organic … See more Web1. Wetting Agent. The wetting agent penetrates deep into the soil, which helps improve water infiltration during irrigation.
