A soil wetting agent can greatly improve the water retention and efficiency of your soil. This is especially true for sandy soils that tend to drain quickly.

Soil wetting agents work by reducing the surface tension of water, allowing it to penetrate deeper into the soil.

This can lead to better plant growth and reduced water loss through runoff.

What Are Soil Wetting Agents?

Soil wetting agents are designed to improve water penetration and distribution in the soil. They help overcome soil water repellency or hydrophobicity, which can cause water to bead up and run off the surface of the lawn rather than soaking into the soil.

A lawn wetting agent, also known as a soil surfactant, is a type of wetting agent specifically designed for lawns. It's a common solution for dry patches across areas of the lawn, even after watering.

Some common situations where wetting agents for lawns are used include tackling water-repellent soil, uneven water distribution, and water conservation. These issues can be frustrating and wasteful, but wetting agents can help resolve them.

Wetting agents come in both granular and liquid forms, making it easy to find a product that suits your needs. Granular wetting agents are best for garden beds and pre-lawn installation, while liquid wetting agents can be used on garden beds and existing lawns.

To use a liquid wetting agent, simply attach a hose-attached bottle product to your hose and water the product in. This makes it easy to apply the wetting agent to your lawn and get the benefits of improved water penetration and distribution.

Do They Improve Yield and Quality?

Wetting agents can have a positive impact on forage quality, but the effect on yield is less clear-cut. In on-farm trials, wetting agents did not significantly impact silage corn yield or small-grain forage yield. However, they sometimes improved the forage quality of corn silage.

The benefits of wetting agents on forage quality are not necessarily reflected in profits, as silage is often not priced or sold based on quality. Wetting agents may not provide a consistent increase in yield or quality, as results from irrigation trials were similar to on-farm trials with no or infrequent differences.

If you're considering using wetting agents, keep in mind that their effects can vary depending on the location and year. In some cases, wetting agents may increase soil moisture, but this is not a consistent result across different studies.

Choosing a wetting agent can be a bit overwhelming, but don't worry, I've got you covered. The type of wetting agent you choose depends on your specific needs, such as whether you're looking to improve water penetration and distribution in the soil, or prevent water repellency problems.

You can choose between granular and liquid wetting agents. Granular wetting agents are best for garden beds and pre-lawn installation, as they can be mixed into the soil, while liquid wetting agents can be used on garden beds and existing lawns.

If you're looking to fix hydrophobic soil, wetting agents can be used regularly on your garden and lawn. They act like a detergent to reduce the surface tension of the water, thereby helping it soak into the soil.

For existing lawns, a hose-attached bottle product is recommended, making it easy to apply the liquid wetting agent directly to the soil.

Choosing Water Retention Products

Some wetting agents, like Primer Select, are specifically designed to prevent water repellency problems and promote uniform turf growth.

Primer Select is a surfactant that can be used to develop an effective rootzone management program, and it's safe for all turf and climate areas.

Wetting agents come in both granular and liquid forms, with granular wetting agents being best for garden beds and pre-lawn installation.

Liquid wetting agents can also be used on garden beds and existing lawns, and are often recommended to be applied using a hose-attached bottle product.

AquaDrive and PeneCal are two wetting agents that were tested in USU studies, but it's worth noting that they didn't consistently increase soil moisture across all locations and years.

Here are some key benefits to consider when choosing a wetting agent:

  • Prevents water repellency problems
  • Promotes uniform turf
  • Establishes a matrix flow in the rootzone
  • Can be catered to different soil types / conditions

Applying During Warmer Months

Applying a wetting agent during warmer months can provide several significant benefits. It improves water penetration and distribution in the soil, allowing water to reach the root zone more effectively.

This is crucial during hotter periods when evaporation rates are high, and water can quickly be lost from the soil surface. A wetting agent helps to reduce water runoff, maximising the efficiency of watering and minimising wastage.

By preventing water from simply running off the lawn, more water is retained for the grass to utilise.

Types and Products

Soil wetting agents come in various forms, each with its own benefits. TriCure Pellets are a fast and convenient method of applying surfactant through hose-end applicators.

They help prevent and treat Localized Dry Spots, improve uniform penetration of water into the soil profile, and enhance recovery of stress-damaged turf. This makes them a great option for supplementing regular water management programs or using on their own.

TriCure Pellets offer several key benefits, including improved turfgrass quality, increased stress tolerance, and protection against Localized Dry Spot.

Here are some key products and their benefits:

  • TriCure Pellets: Help prevent and treat Localized Dry Spots, improve uniform penetration of water into the soil profile, and enhance recovery of stress-damaged turf.
  • Dispatch (Aquatrols product): Helps save water by improving its penetration and infiltration into the soil.

Understanding and Troubleshooting

Soil wetting agents can be a game-changer for gardeners who struggle with dry soil.

To use soil wetting agents effectively, it's essential to understand that they work by reducing the surface tension of water, allowing it to penetrate deeper into the soil.

If your soil is too alkaline, a soil wetting agent may not be effective, as they are most effective in acidic to neutral soils.

A common issue with soil wetting agents is that they can attract pests, such as ants and termites, which can be a problem if not addressed.

What Is Hydrophobic Soil?

Hydrophobic soil is a common problem that can cause serious issues for your gardens and lawns. It's characterized by its ability to repel water, causing it to run off or pool at the surface rather than being absorbed.

Soil becomes hydrophobic when organic matter decomposes, leaving a waxy coating on the soil particles. This can happen in sandy or older soils, and can also be a problem in soils that haven't been watered or fertilized regularly.

Long periods of dryness can expose the hydrophobic surface, making it difficult for water to penetrate. This is why it's essential to address hydrophobic soil issues before they become a major problem.

If you're not sure if you have hydrophobic soil, look for signs like water pooling on the surface or struggling to absorb water. These are clear indicators that your soil needs some attention.

Soil with hydrophobic properties can be challenging to work with, but there are solutions available. Applying a wetting agent can help to reduce surface tension and improve water absorption.

Fixing Hydrophobic Soil

Fixing hydrophobic soil can be a challenge, but it's not impossible. Hydrophobic soils repel water, causing it to run off or pool at the surface.

The first step in fixing hydrophobic soil is to identify the cause. Soil becomes hydrophobic when organic matter decomposes, leaving a waxy coating on the soil particles.

Wetting agents can be used to solve the problem of hydrophobic soil. These agents act like a detergent to reduce the surface tension of the water, helping it soak into the soil.

There are different types of wetting agents available, including granular and liquid forms. Granular wetting agents are best for garden beds and pre-lawn installation, while liquid wetting agents can be used on garden beds and existing lawns.

To determine if your lawn needs a wetting agent, look out for certain signs. If the colour of your lawn gets lighter even after regular watering and soaking, it's a good indication that a wetting agent is needed.

Here are some common signs that your lawn needs a wetting agent:

  • The colour of the lawn gets lighter even after regular watering and soaking.
  • You leave footprints when you walk across the lawn (the 'footprint test' – a healthy lawn will generally bounce straight back).
  • It dries out and feels crunchy underfoot (this generally only happens in the warmer months).

When choosing a wetting agent, look for one that contains specific ingredients such as surfactants, penetrants, stabilisers, and pH adjusters. These ingredients work together to reduce surface tension and improve wetting and spreading properties.

For example, Lawn Soaker is a popular wetting agent that contains these key ingredients and is specifically designed for Melbourne lawns.
