Microbe Plus® Calcium has been created via a unique process that blends and digests calcium nitrates and lactates with beneficial microbes, fungi and bacteria.
Selected trace elements have also been added to create an excellent nutrient supplement.

Utilising a unique digestive process Microbe Plus Calcium is biologically active. It will help rectify calcium deficiencies quickly and effectively.

Calcium regulates the transport of other plant nutrients and is also involved in the activation of certain plant enzymes. It is also an essential nutrient for plant cell division, formation and structure. Calcium is also a catalyst for amino acid production.

The correct balance of calcium provides the foundation for most biological processes in the plant and soil system.

Microbe Plus Calcium is designed as a foliar or drip fertigation product that will deliver an adequate supply of calcium to the plant. The organic acids in Microbe Plus Calcium will also aid the breakdown of insoluble or 'trapped' calcium in the soil converting it into plant available form. The increase in available calcium will improve the uptake of other crop nutrients and improve soil aeration and water movement.

Microbe Plus Calcium delivers a complex suite of nutrients. It combines high grade calcium chelates, magnesium and fulvic acids. It delivers a highly bio-available and digested liquid concentrate.

All the nutrients in Microbe Plus Calcium have been microbially digested using Grow Green’s proprietary blend of beneficial soil microbes. This process emulates the natural process found in nature and converts the nutrients into 100% plant available form.

Active Ingredients

High grade calcium, magnesium and fulvic acids.

Compatibility and Use

Microbe Plus Calcium can be mixed and applied with most commonly used pesticides and fungicides, however, we strongly recommend checking labels for compatibility and testing a small area prior to widespread application.

Optimising for results

For optimum results use with Grow Green’s  Profert® or Microbe Plus® foliar products, along with Xtend® plant oil adjuvant. Xtend will maximise results by reducing spray drift and increasing adherence to the sprayed surface.


Crop Rate/ha* Number of applications
Horticultural crops 4 to 5L 3-4 fertigations: pre-flowering, post flowering & fruit enlargement stage
Broadacre Winter crops 2-3L Liquid injection at seed sowing stage, 2 foliar applications (mid tillering and booting - grain filling stage)
Broadacre Summer crops 4-5L 2-3 boom spray or foliar applications: pre-flowering, post flowering and grain filling stage
Annual and perennial pasture 3-4L 3-4 foliar applications post grazing

*To be diluted in a minimum of 100L of water per hectare.
We recommend foliar spray to the point of run off. Pending soil and leaf analysis, application rates may vary.
The above should 
be used as a guide only.
Avoid spraying in high temperature and high UV conditions.


Microbe Plus Calcium is rain fast in 15 minutes. If rain is expected shortly after applying, application rates listed can be increased by 20%.

Shelf life

Microbe Plus Calcium should be stored at ambient temperature conditions.

It is recommended to be stored out of direct sunlight, but within a well lit area so that the microbial digestion process within the product continues.
Sedimentation will rise after prolonged storage. As such we recommend use within 12 months of the date of manufacture.


Microbe Plus Calcium is available in 20L and 1000L containers.
