Complete Soil Improver | Bag or Tub | 500g-20kg | Treats 200m² applied at 100gsm per 20kg bag


  • Excellent Value! a single 20kg bag is enough to treat an area up to 200m²
  • Complete Soil Improver stimulates and feeds microbial activity within your soil, helping cultivate a healthy micro-biome of symbiotic microbes.
  • Enables greater nutrient uptake from the soil by plants, also greater nutrient and moisture retention. By utilising the symbiotic relationship of plants, soil, microbes, mycorrhizae and zeolites. This product also aids pH stabilisation.
  • Aids flocculation (The process by which soil particles clump together) of the soil, which also serves to aid with aeration and water drainage of soil and creating beneficial root pathways
  • Assists in development of calcium pathways, for maintaining plant health and strength.
  • Improves the CEC (Cation Exchange Capacity) of soil.

Product Description


Complete Soil Improver

Complete Soil Improver is a brand new product to the market, aimed at keeping your soil healthy and fertile. Healthy soil has been proven to improve the robustness and well-being of plants. This results in faster growth, and larger harvests. Healthier soils will often contain naturally occurring peat or humus. These components have become more and more popular for soil improvers and fertiliser products.

In short, we believe Elixir Complete Soil is the best product currently available on the market. It will improve and maintain your soils vitality and enhance its ability to support plant life cycles using naturally occurring ingredients.

Complete Soil aims to reintroduce important natural organic matter and minerals back into the soil. At the same time, it improves the soil structure. These minerals and components are:

Humic and Fulvic Acids

Complete Soil is unique. It takes advantage of the beneficial effects of both Humic and Fulvic acid. This improves “Water-Infiltration” and water holding capacity of the soil. In addition to aiding plant root growth and speeding up plant metabolic rates. Humic acid and Fulvic acid are found in humus, but can be found in any material containing well broken down organic matter. This can include compost, and even some types of soft coal.

Amino Acids

The Amino Acids present in Complete Soil are crucial for plant growth. They are required by all living plants and animals to create the proteins necessary for cell regeneration and growth.


Rockdust is a key part of remineralising soil. It also helps to encourage a healthy micro-biome of symbiotic microbes. These are beneficial to plants as they break down organic matter within the soil. This matter turns into useful minerals and nutrients.


Complete Soil contains Gypsum in order to aid in flocculation of the soil. This is essentially the process by which soil particles clump together. This makes it easier to work with, and is especially effective on looser, sandier soils. This also helps to break down heavy clay soils and flocculate them, making them easier to work with by reducing soil dispersion. Gypsum also contains calcium which is an essential part of the “calcium pathways” in plants. They use this to send signals to other parts of themselves, similar to humans sending signals through the nervous system. The additional calcium “reinforces” these pathways so that the plant doesn’t “forget” how to perform certain tasks (e.g reacting to a drought or a pest invasion).


This invaluable fungi helps release all the nutrients locked up in the soil, phosphorous and nitrogen in particular. There are many types of mycorrhizae. The most common type of the fungi attaches itself to the plant root. It then creates a spider like web throughout the soil which assists greatly in nutrient and moisture retention. Additionally, in drought conditions, some types of mycorrhizae will bore down until they find water and bring the moisture back to the plant.


This important class of mineral is porous. It aids with aeration of the soil. It also helps to improve nutrient and water retention in the soil, further improving the Cation Exchange Capacity (CEC) of the soil. Farmers In Japan have been using these minerals to keep their crops healthy due to the soil nutrients retained by their usage.

Seaweed Meal

Seaweed meal significantly contributes an array of additional micro-nutrients, vitamins, alginates and other bio stimulants. All of which are highly beneficial to soil bacteria and total plant health and growth.

In addition to the mentioned components and their effects, our Complete Soil formula can also increase the Cation Exchange Capacity (CEC) of the soil. It allows the soil to hold more nutrients and minerals, thus helping plants to grow faster and stronger. At the same time, it helps reduce the number of times you will need to fertilise your soil. This is thanks to the various soil-improving actions that it can perform. The presence of zeolites, which give the soil more porosity, nutrient and moisture retention, benefits the CEC.

We’d recommend applying Complete Soil at 100g/m2, to ensure that your soil gets the proper nutrition it needs to continue thriving. We recommend applying this during the summer when micro-organisms in the soil are most active. However, it can also be applied just before planting to ensure that plants get the maximum benefit throughout summer.

It is recommended to store this product in the original packaging in a cool, dry and well-ventilated place. Avoid freezing and direct sunlight. Avoidance of direct contact with skin and eyes through use of protective goggles, gloves and clothing is highly recommended to avoid skin and eye irritation. Refrain from eating, drinking or smoking whilst using this product. Keep out of reach of children.
