Microbe Plus® High N-S has been created via a unique process that blends and digests sulphate of ammonia with beneficial microbes, fungi and bacteria. This process has created a powerful and highly effective nitrogen and sulphur based product.

Utilising our unique digestive process Microbe Plus High N-S is biologically active. It will help rectify relevant nutrient deficiencies quickly and easily.

Grow Green’s unique process of formulation has allowed us to create a highly available soil and plant fertiliser using just under half the nutrient rates of other traditional sulphate of ammonia products, but with equal or better results.

One of the key benefits of Grow Green’s Microbe Plus High N-S is that used at the recommended application rates, it can be foliar sprayed without risk of leaf burning. This provides excellent flexibility with regards to both type and frequency of application.

As a foliar or soil drench application, Microbe Plus High N-S will deliver an excellent supply of nitrogen and sulphur to crops that have a high use of these two nutrients. It provides an efficient and effective alternative to other high nitrogen-based products of twice the strength. Excellent field results have been achieved in both winter and summer cereal crops and pastures.

The inbuilt microbes within Microbe Plus High N-S will also help hold and bind nutrients in the soil thus providing fewer losses via leaching and volatilisation.

All the nutrients in Microbe Plus High N-S 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.

Unlike traditional sulphate of ammonia applications, the microbial action built into Microbe Plus High N-S will also resist making your soil acidic.

Active Ingredients

Technical grade ammonium sulphate, calcium, molasses, potassium, boron, fulvic acid, microbes and fungal promoters.

Compatibility and Use

Microbe Plus High N-S 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  results

For optimum results we recommend use with Grow Green’s  Profert®, Microbe Plus® Pasture; or Xtend® plant oil adjuvant when foliar spraying. Your Grow Green representative will assist in developing application programs specific to your soil and crop.  Xtend will maximise the result by reducing drift and increasing adherence to the sprayed surface.


Microbe Plus High N-S is suitable for use in a wide range of market sectors including pasture, cereal crops, maize, rice, canola, general broad acre winter and summer crops such as millet or sorghum, selected horticultural crops, and turf.

Crop Rate/ha* Number of applications
Horticultural crops 3-5L 3-4 fertigations: pre flowering, post flowering and 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 3-4L 2-3 boom spray application or foliar applications: pre flowering, post flowering and grain filling stage
Annual and perennial pasture 3-4L 3-4 foliar applications post grazing

*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

Rain fast

When used in conjunction with Xtend plant oil adjuvant, Microbe Plus High N-S foliar spray is rain fast in 15 minutes.

Shelf Life

Microbe Plus High N-S should be stored at ambient temperature.

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 High N-S is available in 20L and 1000L containers.
