Aqua Aid brings a wide range of products to the market, offering solutions for various plant related problems. While products are initially designed to solve one single problem, sometimes an unexpected, yet beautiful partnership emerges when two products are applied simultaneously. Today, we want to introduce you to such an extraordinary partnership between two of Aqua Aids prominent products. But first, let us introduce these two remarkable products.

Worm Power is and has been since the start of Aqua Aid Europe, an important specialty product. A 100 % organic vermicomposted product, that strengthens the soil surrounding the plant’s root zone. This healthier soil makes the plant stronger and more resilient. Worm Power provides viable macro and micro-nutrients and increases the water holding capacity (WHC) of the soil. It introduces an active microbial community to the soil, making the nutrient delivery more efficient over an extended period of time. Healthier and stronger plants naturally increase in size and are better able to fight off a variety of threats such as drought and diseases.

Aqua-Boost is a new product in our portfolio, developed by Aqua Aid Europe to increase the plants natural resistance to (negative) external influences. Aqua-Boost is a liquid non-phytotoxic composition, based on natural plant extracts, denaturized extracts and organic compounds. This is a new generation of biostimulant that, due to the very low NPK value, does not interfere with fertiliser programs already applied to the plant and soil. The natural components of Aqua-Boost ‘trick’ the plant into thinking it is under both biotic and abiotic attack. Conveniently, it also contains ingredients to withstand this ‘attack’, enforcing a trigger to the systematic acquired resistance mechanism. This reaction activates the natural hormone production in the plant and with that, the plant strengthens its own immune-system. After application, the plant will be stronger and better equipped to withstand any attack. This results in a plant with more energy to grow, develop a much denser sward and a significantly greater root mass.

But what happens when these products are applied at the same time? Do they contrast or support each other, or do they not effect each other at all? As part of the test setup at Aqua Aid Europe, the products were applied together, both following the standard application advice. As expected, the results showed that Worm Power and Aqua-Boost do not counter each other’s activity. In fact, the test showed that both products actually enhance each other. Aqua-Boost is a feeding source for all the microbes in Worm Power, which kick-starts the latent microbes in Worm Power. More active microbes in the soil allows for a faster nutrient exchange, providing the plant with optimal growing conditions. Some of the microbes in Worm Power are responsible for the nutrient transportation inside the plant, these microbes have readily available nutrients at their disposal due to the addition of Aqua-Boost in the same application. This is very efficient regarding the nutrient exchange in the rootzone.

Worm Power and Aqua-Boost have shown to be very effective products on their own. But combined and creating this newly uncovered ability to elevate each other, they truly proof to be an additional benefit for both the plant and its environment. These test results really do prove that in this case, 1+1 really is 3, without any additional costs.


We all know to apply calcium products, but why is Calcium so important for a healthy soil and strong plants?

In our latest article, we explain in depth why Calcium is vital for both soil and the plants that it grows. Calcium has two major effects in the soil.

Firstly, Calcium works as a bonding agent in the aggregation of soil particles, in which it helps to bind organic and inorganic substances. This is important for the development of a good soil structure. Secondly, it acts as a nutrient filler, to maintain balance amongst nutrients and occupy space which otherwise would be taken up by acidic elements. The high molecular weight and two electrons are the main reasons for these effects. For the entire article, please read The Role of Calcium in the Soil


How does OARS HS compare to other wetting agents in the field?

In order to answer this question, Vos Capelle and Aqua Aid Europe conducted a comparative wetting agent research last year. On Golf Park De Haenen in Teteringen (The Netherlands), a practical test was set up on the Par3 course, to investigate the functioning of different surfactants. The most commonly used wetting agents in The Netherlands were included in this test set-up. During the entire growing season, the performance (effectiveness), duration of action and uniformity of all products were examined and compared. Please continue here to see our wetting agent research.




X-ray vision in sports grass; newest research method used in sports grass

Research method from space travel applied in sports turf. In a leading study led by Dr. Jim Brosnan of the University of Tennessee (USA) a research technique used in space has been applied to document and study unaffected root growth. Recently, a research has been done using this method to evaluate the effects of Aqua Aid’s Worm Power Turf on root development. Read on here.




Trials conducted at Penn State University USA confirmed the effectiveness of pure OARS liquid against fairy rings. Significant reduction in the fairy ring severity from status 8 (Type 1 severe)  to status 1 (slight/no symptoms) in 10 days.

The Organic Acid Redistribution System is a great tool in reducing the visual effects and is a 100% biological approach to battle Fairy rings symptoms.

Between 2016 – 2019, Aqua Aid Europe has been performing various field trials to see the water saving benefits in of multi-branched surfactants in turf grass, especially PBS150. Penn State University has proven considerable reduction in different conditions in 2 projects. Following these trials, Secret Valley Golf Resort on Cyprus, has used PBS150 to combat a lack of water caused by climate change. Want to know how? READ ON

Late summer and early fall is a great time of year to use VerdeCal GVerdeCal G can offer some relief by releasing calcium and thus, conditioning the soil and making other nutrients available. These newly available nutrients can offer your turf some of the relief it needs at a time when it may need it most. It is really about the volume of calcium. By releasing “real pounds” of calcium into the soil structure - in various forms, thorough conditioning of the soil can occur. This may be visually seen as green up, growth, rooting, stress reduction, and perhaps even some disease relief. We do not claim VerdeCal G will cure disease, but feedback certainly tells us that the benefit of available calcium can make a difference. Remember, better uptake and translocation of nutrients and water will always benefit the turf and allow the turf to withstand stresses better.



Often we receive the feedback from the market that a comparison of VerdeCal G and a classic gypsum would be helpful.

We aim to please, so we have created a fact sheet showing the differences and, therefore, benefits of using VerdeCal G.

Hans de Kort, director of Aqua Aid Europe explained to Pitchcare why a new vermicomposted liquid fertiliser is different from other tea-based products on the market, and how the product benefits root system development to create a stronger, healthier strand of turf and healthier roots.

What exactly is it?

WormPower is a vermicomposted liquid fertiliser. It’s made strictly from the company’s OMRI-listed vermicompost (which is produced on site in our facility) and water, which are the only two ingredients. This sets it apart from a lot of other vermicompost products, and we refer to the product as a liquid extract. You’ll hear in the industry, the jargon is compost tea. For us, we view that as kind of a pejorative.

With other teas and products like it, the big goal seems to be that, if billions of microbes are a good thing, then trillions are better. So people want microbial blooms in their products. In our opinion, that’s really not the important thing. The numbers aren’t important. The important thing is the broad spectrum of colonies that we achieve, and the viability of those colonies once they hit the soil.

How does it work?

What the liquid really is, is a vector for thousands of microbial communities that will essentially colonise the rootzone of any plant they’re applied to. It has a particularly beneficial effect on turf, in that it creates very strong root systems without any undue top growth. That’s really been one of the things that’s been a boon to golf course superintendents. It doesn’t do them any good to have a good root system, but then have to go out and double their labour costs by mowing twice as much as they used to. It’s really an effective tool in terms of solely focusing on the increased root mass and increased development that helps promote a stronger plant, but not overly vigorous growth.

These benefits accrue to the soil through the product, but really, these benefits come from the worm.

But why not just use compost?

After the composting process, you have achieved a level of microbial inoculation that is specific to the high temperature ranges that occur in composting, what we call thermophilic microbes that operate above 50°C. Worms, however, live in the rhizosphere of the plant and all the microbes that are both in the worm and on the worm are imparted to the vermicompost. These microbes are the ones that live and thrive in the middle temperature ranges, the mesophilic microbial communities. Once the product goes into the soil, they are in an environment in which they are able to thrive.

What kinds of rates are effective?

The most effective application rate is 50 litres per hectare per month. Whether it be greens or fairways or tees, if you’re going to do that, the application rate breaks down to two things; either 25 litres every two weeks, or 50 litres every four weeks. Really, which way the course manager chooses to do it is dependent on a couple of different factors. The effectiveness of the product for thatch reduction is more clearly visible when you do the 50 litres rate every four weeks. At the same time, if what they’re really after is increased root mass and density, then we’ve found that 25 litres every two weeks will promote better root development. Both are effective rates, and certainly outperform other applications and any control in testing.

Can it be mixed with other products?

We’ve had great success when it’s being mixed with surfactants, especially with the notion that the material is supposed to work in the rootzone. Anything that helps with that soil penetration is fantastic. We are seeing great results with a number of products tank-mixed with WormPower. There’s also work that’s been done with North Carolina State University. One of our early recommendations was not to tank-mix with fungicides. That becomes a labour issue if it requires another pass. Over multiple facilities throughout the US over the past two years, agronomic programmes have mixed fungicides with it and have seen zero negative effects. This real-world research, along with the statistical counts we have proven through university research in multiple trials, shows that the product can be mixed with any others that have to be incorporated into a soil-drench programme.

What should course managers keep in mind when using it?

In the summer of 2015, I was responsible for travelling to golf courses in our course trials, and interestingly, as I was following up with them, I heard, “I’m not seeing anything. Nothing’s happening.” And I knew why they were saying that, because they weren’t looking below the surface. Anyone who tries this, if they don’t do a cup cut and pull some plugs, they’re not going to see what’s happening. Look below the surface and you’ll find the benefits. Don’t think you’re going to see it manifest itself in a physical plant response above the surface. The top growth is not going to change a lot. You’ll find that the top growth responds over time by being more drought- tolerant and standing up to traffic better and things like that, but you just don’t get that visible response on the top growth. The main thing is that you want it to be used as a soil spray. It can be effective as a foliar application, but it works in the rootzone. We want it working in the soil.

Watch the rootzone

That’s where you’re going to see the benefits and, over time, you’ll realise the benefits of a healthier rootzone. Don’t expect to see a growth explosion right under your eyes. Get a cup cutter out and start taking some cuts; you’ll see the benefits pretty quickly.
