£10.80

A 100% organic microbial inoculant designed to establish beneficial microlife in the growing medium and support a healthier, more active root zone.

Aptus Micromix Soil is a concentrated dry microbial inoculant containing a carefully selected mixture of beneficial microorganisms and stimulants. It is designed to introduce beneficial microlife directly into the growing medium, helping create better biological conditions around developing roots.

Commercial growing substrates are often processed or sterilised to remove potentially harmful organisms. While this produces a clean growing medium, it can also remove much of the beneficial microlife that would naturally occupy the root zone. Micromix Soil allows growers to deliberately reintroduce beneficial microorganisms when preparing substrate or transplanting.

Once established, these beneficial populations help create a more favourable environment around the roots. Aptus states that enzymes produced by beneficial bacteria help break down accumulated nutrient salts, while healthy populations of beneficial microorganisms help protect the root system from undesirable microorganisms.

Micromix Soil can be mixed throughout the growing medium at 0.5 – 1g per litre of substrate or applied more precisely at 1g per planting hole before planting or transplanting.

Why choose Aptus Micromix Soil?

  • Establishes beneficial microlife – introduces selected microorganisms into the growing medium to create a biologically active root environment.
  • Supports healthy roots – beneficial microbial populations help create favourable conditions around the developing root system.
  • Helps protect the root zone – Aptus states that healthy populations of beneficial microorganisms help protect roots from harmful fungi and bacteria.
  • Stimulates rooting and growth – designed to support the biological processes associated with healthy root establishment and plant development.
  • Helps process accumulated nutrient salts – enzymes produced by beneficial bacteria help break down accumulated salts within the growing medium.
  • Ideal at transplanting – can be applied directly into the planting hole, placing beneficial microorganisms close to developing roots.
  • Can be mixed through substrate – suitable for incorporating into growing media before planting.
  • Suitable for different substrates – Aptus recommends Micromix for use across a wide range of growing media.
  • 100% organic – a biological approach to improving root-zone conditions rather than simply increasing mineral fertiliser inputs.
  • Works with Micromix Drip – the initial Soil treatment can be followed with Micromix Drip after 21 days where continued microbial inoculation is required.

What is Aptus Micromix Soil suitable for?

Micromix Soil is particularly useful when preparing fresh growing media or transplanting young plants. These are ideal opportunities to introduce beneficial microorganisms because the product can be distributed throughout the substrate or positioned directly around the developing root zone.

It is well suited to growers who want to establish beneficial biology in substrates that may contain relatively little active microlife. Rather than waiting for microbial populations to develop naturally, Micromix Soil provides a deliberate inoculation at the beginning of the crop.

Aptus recommends Micromix Soil during plant establishment and vegetative growth to support healthier young plants and root development. It can also be used with different types of growing substrate, making it suitable for a wide range of container and substrate-based growing programmes.

Micromix Soil and Mycor Mix perform different jobs. Mycor Mix supplies beneficial mycorrhizal fungi that establish a symbiotic relationship with roots, while Micromix Soil supplies a broader mixture of beneficial microorganisms and stimulants intended to establish healthy soil-borne microlife. The two products can therefore form complementary parts of a biologically active root-zone programme.

How to use Aptus Micromix Soil

When preparing growing media, mix 0.5 – 1g of Aptus Micromix Soil per litre of substrate. Distribute the powder evenly through the medium before planting.

At the lower rate, use 5g for 10L, 25g for 50L or 50g for 100L of substrate. At the higher rate, use 10g for 10L, 50g for 50L or 100g for 100L.

Alternatively, apply 1g directly into each planting hole before planting or transplanting. This method places the beneficial microbial inoculant immediately around the developing root zone without requiring it to be mixed through the entire volume of substrate.

When using the planting-hole method, a 100g pouch provides approximately 100 individual 1g applications.

Micromix Soil is the substrate-applied version of the Aptus Micromix system. Where further inoculation is required after establishment, Aptus recommends an optional application of Micromix Drip after approximately 21 days.

Aptus Micromix Soil FAQs

What is Aptus Micromix Soil?

Aptus Micromix Soil is a 100% organic dry microbial inoculant containing selected beneficial microorganisms and stimulants. It is designed to establish beneficial microlife within the growing medium and around the root system.

What does Aptus Micromix Soil do?

Micromix Soil helps establish a healthy population of beneficial microorganisms in the root zone. Aptus states that these microorganisms support rooting and growth, help protect roots from harmful microorganisms and produce enzymes that break down accumulated nutrient salts.

How much Aptus Micromix Soil should I use?

Mix 0.5 – 1g per litre of growing substrate. Alternatively, apply 1g directly into each planting hole before planting or transplanting.

How much Micromix Soil do I need for 50 litres of substrate?

For 50 litres of substrate, use 25 – 50g of Micromix Soil depending on the chosen application rate.

How much Micromix Soil do I need for 100 litres of substrate?

Use 50 – 100g of Micromix Soil for 100 litres of growing medium.

How many plants will 100g of Aptus Micromix Soil treat?

When applying 1g directly into each planting hole, a 100g pouch provides approximately 100 plant applications.

When should I apply Aptus Micromix Soil?

Micromix Soil is particularly useful when preparing substrate and during planting or transplanting. Applying it at this stage establishes beneficial microlife close to young and developing roots.

Can Aptus Micromix Soil be mixed into growing media?

Yes. Aptus recommends mixing 0.5 – 1g per litre directly through the substrate. It can also be applied at 1g per planting hole if a more targeted application is preferred.

Is Aptus Micromix Soil organic?

Yes. Aptus describes Micromix Soil as 100% organic.

Does Aptus Micromix Soil contain beneficial bacteria?

Micromix Soil contains a selected mixture of beneficial microorganisms and stimulants. Aptus specifically describes enzymes produced by beneficial bacteria as part of the way the product works within the growing medium.

What is the difference between Aptus Micromix Soil and Micromix Drip?

Micromix Soil is designed to be mixed directly into substrate or placed in the planting hole. Micromix Drip is mixed with water and applied through irrigation or watering. Aptus recommends Micromix Drip as an optional follow-up approximately 21 days after the initial Micromix Soil treatment.

What is the difference between Aptus Micromix Soil and Mycor Mix?

Micromix Soil supplies a mixture of beneficial microorganisms and stimulants to establish healthy soil-borne microlife. Mycor Mix specifically contains beneficial endomycorrhizal fungi that establish a symbiotic relationship with plant roots. They are different biological products and perform complementary roles within the root zone.

Does Aptus Micromix Soil help with nutrient salt build-up?

Aptus states that enzymes produced by beneficial bacteria help decompose accumulated nutrient salts within the growing medium, making this one of the functions of the beneficial microbial population established by Micromix.

Can Aptus Micromix Soil help young plants establish?

Yes. Aptus recommends Micromix Soil during the growth phase to support healthier young plants and better establishment. Introducing beneficial microlife early helps create a more favourable biological environment around developing roots.
