Microbe Plus® PhosCal

Product Description and Characteristics

Unique liquid that blends and digests phosphorous acid and calcium carbonates together

Microbe plus® PhosCal has been created via a unique process that blends and digests phosphorus acid and calcium carbonates together with selected trace elements creating an excellent nutrient supplement.


Utilising a unique digestive process Microbe Plus PhosCal is biologically active. It will help rectify nutrient deficiencies quickly and effectively. The correct balance of phosphorus and calcium is required for plants to produce the sugars required for normal growth. Plant deficiencies in phosphorus and calcium can predispose a plant to fungal and bacterial infection.

Correct levels of plant available phosphorus and calcium are required for normal root growth, nutrient uptake and photosynthesis. When these nutrients are lacking, root growth will be delayed and stunted. Nutrient uptake and plant photosynthesis will also be hindered. These nutrients are essential for plant health and cell wall integrity.

Generally phosphorus acid is not a plant available form of phosphorus but due to our unique microbial digestive process and the form of calcium used – it will convert into available phosphorus for the plant. Phosphorus is an essential element for flower and fruit formation. Phosphorus is easily locked up in the soil. Microbe Plus PhosCal via foliar spray or soil drench is an efficient method of application during high demand times such as seeding and fruit development.

Calcium regulates the transport of other plant nutrients and is also involved in the activation of certain plant enzymes. It is also essential for plant cell division and is a catalyst for amino acid production. It is a critical element for biological processes in the plant. All the nutrients in Microbe Plus Phoscal 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.


Microbe Plus PhosCal is suitable for use in a wide range of market sectors including Pasture, Dairy, Sugar, Broadacre, Horticulture, Viticulture, Turf, Golf Courses, Bowling Greens and Race Courses.

For optimal results, it is recommended to use Microbe Plus™ PhosCal with Amino Elite® or with the Xtend™ plant oil adjuvant, registered by GrowGreen Australia. Its application ensures better wetting of the treated surface and prolongs the retention time of the solution on the leaves.

Microbe Plus™ PhosCal should be stored at ambient temperature out of direct sunlight but within a well lit area so that the microbial digestion process within the product continues.

Microbe Plus™ PhosCal should be stored at +5°C to +35°C.For prolonged exposure to lower temperatures, IBC containers are preheated for 24 hours prior to application to activate microbial activity. Exposure to direct sunlight is not recommended, but it is desirable to keep the product in a well-lit place so that the microbiological process is not interrupted. It is recommended to use within 14 months of the date of manufacture.

How GrowGreen Fertilizers help Plants against Drought

Drought is a devastating natural hazard, due to the negative effects of the climatic change, the percentage of the planet affected by drought has more than doubled in the last 40 years (FAO). Water deficit in plants is considered as one of the major abiotic stresses (Jaleel et al., 2009). Plants exposed to severe drought
