I hate watching established plants die, so the bulk of my precious gardening time is spent watering plants just to keep them alive. Usually this is enough to see them through until rain decides to show up, but this drought is different. It comes hard on the heels of two floods the most recent in January last year that stripped goodness from the soil. As a consequence, the ground in some parts of my garden has become water repellent, or to use the technical term, hydrophobic. In some circles, soil wetters have earned a bad rap, copping the blame for killing plants, destroying micro-organisms and even making the soil more hydrophobic. But the thing to bear in mind is that not all wetting agents are created equal.

Jerry uses a range of techniques to prevent his soil from becoming hydrophobic and repelling water during periods of dry weather, focusing on soil improvement. Using the principles of succession mulching, Jerry initially added aged mushroom compost to the soil, followed a season later with a topping of pine bark mulch, then tea tree mulch the following season. The current mulch layer is a straw-based mulch of sugar cane. Each of the mulches Jerry utilises favours a different group of soil microorganisms, and over the years of succession mulching, these microbes have built up to allow the soil to accept the rainwater when it falls. Both pine bark and eucalypt bark mulches are fantastic in the garden and have many applications, but it is important to remember that they may become counter-productive over time, given their relationship with some soil-borne fungi. If used over long periods of time, the mulch and fungi can bond and form plates, preventing the deep penetration of water and oxygen. To combat this, Jerry makes his own wetting agent from readily available food grade agar, a gelatine made from seaweed. Watering the soil before you are going to add the wetting agent will aid both the dispersal and effectiveness of the wetting agent. You can expect the effects of this application to last around three weeks, which while shorter than the commercially available products, means that it is readily biodegradable and far kinder to the soil. It is also the perfect amount of time for a tender young seedling to establish during the warmer months. In this episode.

Others contain only naturally occurring substances that readily biodegrade and cause no ill effects to the soil or plants. Bee Winfield says:.

Water repellant soils can be improved a number of ways so that they absorb and retain water more effectively, prolonging the benefits of watering and rainfall. Healthy soil biology is an important and overlooked aspect. Ignore the good guys at your peril. Soils repeatedly mulched with woodchip made from pine bark or eucalyptus woodchip gradually become water repellant. They stimulate a population boost of a narrow range of wood digesting fungi.

Gardeners with pot plants, or a sandy garden, are likely to have experienced water repellent or hydrophobic soils. Soils become hydrophobic when they are dry for extended periods - particularly when the dryness is combined with a high organic content. But these days there are many soil wetting agents on the market intended to help soil absorb water. According to soil scientist, Dr Peter May, there is a simple experiment people can undertake at home to see whether they have hydrophobic soil. Make a well in the top and then pour on some water. If the soil is hydrophobic, the water will pool on top. In contrast when you wet soil that is not hydrophobic, the water is quickly absorbed," he said. The simplest way to improve water take up by hydrophobic soils is to use a soil wetting agent. Wetting agents are like detergents.

With water conservation becoming more and more of a necessity, wetting agents can make it easier to have the lush lawn you want without running up your water bill or running into a water restriction. Commercial wetting agents, however, can be pricey or hard to find- especially if your lawn already has all of the fertilizer it needs. Wetting agents are used in lawn care, for example, to apply foliar feed, liquid fertilizer, or to deliver more water to plants faster than applying the water without a wetting agent. Of these, the following four are the best options. All of them are inexpensive and worth having around, especially in hot climates or places with sandy or rocky soil.

In horticulture using an anionic surfactant can cause problems with sprayers that have an agitator, or where foam could disrupt water flow or the action of pumps. The Australian Standard for the biodegradability of detergents applies only to the active ingredient, not to any of the many additives they contain, like chemical fragrances. Why not save money by using household soaps and detergents? Consequently, roots will be attacked by pathogenic fungi, nematodes and bacteria. Eva says:. Wetting Agents Wetting agents are a great quick fix but will not resolve the issue long-term. Most moisture-loving plants prefer good or average drainage. Leave a comment Cancel reply. But natural wetting agents, including soaps, saponins and microbial wetting agents are allowed in organic gardens because they are beneficial and sustainable. Apply this over well-watered soil. Wondering if instead of agar agar could I make a paste from cornflour and dilute it through with liquid green manure tea. Almost all plants have mycorrhizal fungal associations in their root systems and these fungi serve as accessories to the plant root system, greatly extending the capacity to absorb water. These compounds are also known as surfactants and they work by reducing the surface tension of water, helping it to spread evenly. Worse can happen.

Levelled beds will always be easier to water and less likely to shed heavy rainfall and irrigation than sloping beds. Almost all plants have mycorrhizal fungal associations in their root systems and these fungi serve as accessories to the plant root system, greatly extending the capacity to absorb water. Luckily, it is not too hard to fix, here's a few common ways you can improve your soil to make it water-loving, or 'hydrophilic'. Add this mixture to a 9-litre watering can and fill with water to dilute the mixture. You can identify hydrophobic soil by watering it. More from ABC. Soils affected by dryland salinity, such as parts of western Sydney, lose their natural crumb-like structure making it harder for air pockets to occur in the soil. I just wanted to thank you for your sensible info but also to find out whether you had any revisions to this seeing that it is 15 yrs old — that is, any new products that are acceptable, any changes or updates?
