Fertilise Smarter, Not Harder

One Simple System

for Your Entire Garden

When it's time to fertilise, simply follow your rotation and treat your entire garden – indoors and out – in one go.

Why One System Works Better

🕐 Save Time – One rotation for the whole garden
💰 Save Money – No multiple product lines needed
🌍 Better Results – Consistent, balanced nutrition
🧪 Mix & Match – Combine liquids for easy application when your time poor With Soil Dynamics, every product works together seamlessly.
The result? More time enjoying your garden, less time (and money) spent maintaining it.


Why Our System is Different

Unlike synthetic fertilisers that feed plants directly, Soil Dynamics products work by nourishing your soil. Think of it as creating a Living Smorgasbord – your soil becomes a buffet where plants can choose exactly what they need, when they need it.

This means you can relax about measurements. Our products won't burn your plants from over-application because they work through the soil. The only burn risk? Leaving liquid residue on leaves in hot sun – the sun acts like a magnifying glass. Simply water in the morning or evening, or hose off any residue on foliage. 

What IS important: Following the rotation schedule. While application quantities are forgiving, using the right product at the right time matters. Each product is formulated for specific plant growth stages. For example, using Regenerate Elixir right after planting can cause burn because it's designed for established plants, not young transplants. Stick to the rotation, and your garden will thrive.


In short: Don't stress about perfect measurements, but DO follow the weekly schedule for best results

Weekly Liquid Rotation Schedule

Follow this simple weekly schedule:
Our commercial-grade liquid concentrates offer exceptional coverage and value. When diluted in a 9-litre watering can, they cover 8-10m² per application—that's 2-5x more coverage than typical home garden fertilisers (which usually only cover 2-4m²). So you're getting premium organic nutrition that's actually more cost-effective

  1. Week 1: Happy Gut Tonic
  2. Week 2: Protein Shake
  3. Week 3: Jurassic Juice
  4. Week 4: Happy Gut Tonic
  5. Week 5: Protein Shake
  6. Week 6: Regenerate Elixir

Then repeat the cycle.

Note: It's okay to miss a week or mix products together if you're time-poor.

💡 Pro Tip: All our liquids can be mixed together for convenience – just don't store them pre-mixed.

When to Apply Each Product

Nutrient Rock Star and Growing Goodness
Apply at these key times:

At planting (mix into soil)
First flower/budburst (sprinkle on top, water in)
Before ripening (sprinkle on top, water in)
Plants showing signs of nutrient deficiency (yellowing, interveinal chlorosis)
Seasonally as needed
Growing Goodness is only needed for heavy feeders like citrus, avocados, and root vegetables.

Happy Gut Tonic
Post planting
For transplanting: soak in a bath 2-24 hours prior
Apply fortnightly

The Protein Shake
Apply 2 weeks post planting
At any stage to drive plant growth
Apply fortnightly

Jurassic Juice
Apply at any stage to stimulate microbes and build soil structure
Ideal for hydrophobic soils and pot plants: apply weekly at the higher rate, then fortnightly, then back off to monthly once soil structure has built and it is far less hydrophobic

Regenerate Elixir
Apply 4-6 weeks post-planting
Great for seed soaking
Around flowering
End of season

Fixing Hydrophobic Soil in Existing Gardens

Initial Treatment:
Apply Nutrient Rock Star at 3 handfuls per m² (supplies minerals, nutrients, plus bentonite, zeolite, and spongolite to combat water repellency

Intensive 6-Week Program:
Week 1: Water in Nutrient Rock Star with Jurassic Juice at 50-100ml per 9L
Weeks 2-6: Continue Jurassic Juice at 50-100ml per 9L (weekly)
Weeks 7+: Reduce to fortnightly until you see improvement
Maintenance: Monthly applications year-round
Summer Boost: Return to fortnightly during warmer months if you see signs of water repllency

✅ Continue rotating other liquid products alongside the Jurassic Juice throughout this program (remember you can mix our products throughout this time so add the Jurassic Juice in with all your other liquids for ease)

Read our BLOG on Hydrophobic Soils

Clay & Compacted Soil Solution

Jurassic Juice helps open tight, compacted clay soils, allowing water, air, and nutrients to move freely. This improves soil structure, supports healthier root growth, and helps your fertiliser work more effectively.

Follow the same Initial Treatment and Intensive 6-week program as the Hydrophobic Soil Solution.

Then continue with regular maintenance applications

✅ Continue rotating other liquid products alongside the Jurassic Juice throughout this program (remember you can mix our products throughout this time, so add the Jurassic Juice in with all your other liquids for ease)

Garden Calculator - your 3-month Program

Input your approximate square metre rate you which to treat and it will calculate your approximate requirement as well as give you a printable 3- months application guide plan. Link Below

NB: this is based on the General Application rate

Pro Tip 1 : For existing Gardens struggling with hydrophobic and Clay Soil you may want to consider upping the Jurassic Juice as it requires 50-100ml per 9lt for approximately 10 weeks, opposed to its general application rate of 20ml per 9lt.

Pro Tip 2: for non-existing Gardens dealing with sandy soil and Pot plants we recommend purchasing the Coastal Cure - (this is not included in your calculator)

-For gardens, the recommended rate of application is 1 kg per sqm

- For pots 1 cup per 20lt potting mix.

"A Snippet of what our Fellow Gardeners have to Say" 

Magic Dust 

This is one of the products that's a non-negotiable for the garden. As a registered nutritionist it makes sense that we ensure the plants we grow have the best opportunity to produce mineral-dense food

 Soil Dynamics has changed how I garden

Gone is the cupboard full of products and me not knowing when to use them and how often. I have Soil Dynamics individual products on rotation each week and I can look up what each product does for my plants, how to start each season with the right products to get the veggies going. They are both so helpful with any questions I have. I think Soil Dynamics are the best and I highly reccomment them. 

Amanda Onus 

Best Vege Growth and Vigour Ever 

I implemented a new program after coming across your products four months ago. I am brewing my own worm tea, adding Happy Gut Tonic and The Protein Shake in as well as uncultured molasses. This is liberally applied every 10- 14 days. Additionally Jurassic Juice and Regenerate Elixr into alternated batches. As well as this I have altered my watering regime, only using filtered water or scheme water left standing for 24 hours in open barrels.

The outcome has been outstanding to date with lush vigorous growth I have seldom ever achieved before, never to this consistency.

It will be interesting with the coming heatwave to see how everything goes, to date freshly planted seedlings are bouncing out of the ground.

To date, very happy with your products, cheers

Soil Dynamics Convert

I have been using the Soil Dynamics products for several years now after trying so many different products that didn't work for me and my garden. The advice that Anthony and Tini have given me has been invaluable in getting the right solution, my plants are the happiest I have ever seen them.

I bought this for a friend after they asked how my garden looked so good and they are now a Soil Dynamics convert.

I cannot recommend these products more highly and if I could give a higher rating I would.

Regenerate- the name says it all!!

I was recommended this product to put on my tomatoes to help with blossom end rot because it contains calcium and it worked!! Plus, after reading the label I realised how much more this amazing product has in it! It’s packed with so many trace elements and i quickly worked out I can use it on all my plants both inside and outside and the results have been out of this world!! You have to try it out… you won’t be disappointed!!!!

Best Ever

Absolutely love these products. Applied early autumn for winter crops. Everything has gone bezerk. Great in growth and amazing green colour. I have been growing veggies for 50 years plus. I tried every trick in the book. Soil Dynamics are the best by far. Can’t speak highly enough of them.

Understanding Our Products

Treat your soil like your gut they are both microbiomes that function the same. As the saying goes - " You are what you Eat " and so is your soil!

The Purpose of each Product

LET'S FIRST START WITH THE BELOW:
We all know the importance of a balanced diet for ourselves. But your plants crave variety just as much as we do? They're not simply sunbathers – they're sophisticated gourmands requiring a rich smorgasbord of nutrients from the soil.

WHY MINERALS & NUTRIENTS- Nutrient Rock Star
Like all living things, plants need minerals and nutrients to thrive. These elements are needed for growth, metabolic functioning and the completion of its life cycle.

WHY MICRONUTRIENTS- Happy Gut Tonic 
These are your trace elements required to build strength immunity and resilience.

WHY PROTEINS & FATS- The Protein Shake 
Proteins are an essential part of all living organisms, they create structural components of tissue enzymes and antibodies. They are composed of one or more long chains of amino acids.The reason plants need fat is very similar to why we humans need it. It is a denser store of energy. A specific weight of fat will contain more energy than the same weight of carbohydrates. Fats are present as lipids in plants.

WHY CARBOHYDRATES- Jurassic Juice
Like all living organisms, plants and microbes require energy in its simplest form so they can grow and carry out basic life functions. Plants produce, store and burn carbohydrates in the form of sugar to provide themselves with energy.

WHY CALCIUM - Regenerate Elxir                                                                        These are the bones to cellular structure that everyone needs to create the bones of your body, the stronger the better .

ENERGY - Growing GoodnessRepairs tissues, regulates systems, and provides essential vitamins and minerals, required to thrive.

CARBON, THE KEYUnderstanding soil biology and building the connection between soil and plant can be a bit like finding the right key to open the door.


Carbon is the home and the power supply for all microbes which in fact are the guys that make your plants grow.
 
Plants put carbon into the soil via their root system. By growing healthy plants fed with a diverse range of biostimulants will allow you to build soil carbon, resulting in the regeneration of your soil – nature then does the rest.

Microbes are such an important part of this process and it is essential that they are looked after.

Just like humans and all animals gut microbiome – microbes need all the food groups just as much as we do to be healthy and to function properly.
 
Soil Dynamics certified biostimulants provide this diverse range of carbon-based food groups
 
After all "You are what you eat" and so is your soil  …

So the answer is Simple here at Soil Dynamics Anthony Quinlan (B.Sc) has designed an entire range for your home garden to address every food group required with our 6 products 

 “It is all intertwined soil, plant & human health, you cannot have one without the other .

Do I Need all your Products?

"No" is the short answer.

In an ideal world "YES" as diversity creates diversity

But we want you to feel comfortable and know that each product can be the beginning to "Your Soil Health Journey"

If we had to choose just 1 of our products, it would be the Nutrient Rock Star in most situations.

That said the Starter Kit is your best first option to dip our toes.

Alternatively, we now have our Foundation Bundle in XSM(5 products- all 4 liquids and the Nutrient Rock Star) for those who want to trial them first in a smaller section of their garden, and or ideal for patio and indoor plants

Do our Products Expire

Short answer NO - they don't

Best practice is to keep them in a cool dry place.

If you are concerned they have expired, then you haven't used them enough and I'm sure your garden isn't thriving.

When growing plants of any kind, they take nutrients from the soil. This is why it is important to feed the soil regularly.

Pro tip : if it has been a while since using - shake liquids, well before use

Connection Between Soil Microbes and our Gut Health

The connection between soil microbes and gut health lies within our gut and is home to trillions of bacteria that make up our microbiome. This microbiome plays a vital role in various aspects of our health, including digestion, immune function, and even mental well-being. For this reason, we need to stimulate these microbes by offering all food groups.

It all comes down to:

"Diversity, Moderation and Consistency"

Modern agricultural practices such as pesticide use and synthetic fertilisers, negatively impact soil microbial communities. The presence of beneficial microbes in the microbiome, enhances nutrient absorption, promotes a healthy balance of bacteria, and supports overall digestive function.

The microbial health of our gut is inextricably linked to the health of the microbes in the soil. We are at the stage now in our human evolution where we are just beginning to understand what soil microorganisms do.

The plants you eat & harbour microbes from the soil they were grown in. When you consume these plants, you're introducing those microbes to your gut, boosting its diversity. It's a fascinating two-way street and worthwhile exploring.

Research suggests that individuals who consume diets rich in fruits, vegetables, whole grains, and other plant-based foods tend to have a diverse and healthy gut microbiome. This diversity is associated with better overall immunity and health outcomes. The more diverse the gut microbiome is, the more resilient and capable the gut is (especially to fight of disease), as well as more efficient in breaking down essential substances. Since the human diet is very diverse, many substances need to be broken down and the more variety of microorganisms there are present, the higher the chances that each substance will be broken down.

Going back to the research, we now know that due to the rise in chemical inputs and packaged food consumption, we have diminished our food diversity for certain microorganisms to survive. One could say we have made some microorganisms extinct. No doubt leaving behind a world of greater disease and susceptibility.

An interesting fact the word Disease stems from dis ease.  Meaning it puts our body into a state of dis ease. 

The soil microorganisms in broad view serve the same goals as the gut microorganisms to break down essential nutrients, aid in growth and nutrition, and aid in disease resistance. The soil has direct contact with plant roots which is one of the main ways how plants attain their nutrition and maintain their health. Soil microorganisms’ function in nitrogen fixation, phosphorus solubilising, and suppression of pathogens and diseases that can come in contact with the plant roots. Microorganisms help feed the plant as well as protect the plants from stress from both biotic and abiotic factors (i.e. viruses and weather). Microorganisms also aid in the sprouting of seeds. The same concept goes for the diversity of microorganisms in the soil as is in the gut; the more variety, the higher the chances the plant will get proper nutrition and protection.In general terms, the more variety of microorganisms, the better and the only way to get more variety is by providing all the food groups to your soil via bio-stimulants and organic inputs. 

Soil microorganisms cycle nutrients and water to plants and ultimately to our food and the human organism. By understanding the parallels between our gut microbiome and soil ecology, we can appreciate the interconnectedness of life and the importance of fostering diversity in both realms. Just like a healthy garden relies on a variety of creatures, from earthworms to pollinators, a balanced gut microbiome depends on a multitude of bacteria, fungi, and other microscopic partners. These microbial communities play a symphony of roles, from breaking down food and recycling nutrients to bolstering our immune system and promoting plant growth.

This process enhances nutrient availability and uptake by plants, leading to healthier and more productive crops. Just as some soil microbes decompose organic matter while others stabilise the soil structure, our gut inhabitants also work together in a beautiful symphony. These microbes help digest our food, while "stabilising" and therfore one maintains a healthy gut environment. Additionally, beneficial soil microbes can help suppress plant diseases. Some microbial species have the ability to inhibit or compete with pathogenic organisms, reducing the risk of crop infections and increasing natural plant immunity.

Reintroducing beneficial soil bacteria to depleted soil is akin to eating naturally cultured and grown foods to restore the gut microbiome.

Pro tip: You don't need to buy microbes as an input, as if you are adding foreign microbes to your soil the chances of their survival is minimal unless the fertilisers already has been microbially digested such as our Nutrient Rock Star as this means they are already stimulated in a natural environment (inside our bucket) and will therefore thrive if applied and then fed.

Your best option is to compost ( at home, we add our Nutrient Rock Star into our compost) and use a diverse range of food groups to stimulate and attract microbes already in your natural environment, which will bring them to life.
