Pastoral Farming

Using EM will improve crop and pasture yields and enhance fertiliser performance. 

The applications in pasture are centred around improving your biggest asset….your soil. 

EM works by getting the natural processes to function, the way nature intended by stimulating biological activity in the soil and plant. EM will enhance soil and pasture performance through:

  • Solubilising nutrient compounds for uptake by the plants root system
  • Converting dead and organic matter for increased biology and fertility
  • Producing growth promoting substances that increase plant production
  • Suppressing harmful pathogens
  • Increasing carbon and nitrogen fixation
  • Stimulating mychorrizal activity and earthworm
  • Increasing nutrient uptake in pasture
  • Improving photosynthesis of plants

Therefore you will see gains in: yield, fertility and soil structure. Read more about what EM does in your soil.

A healthy soil and stimulated biological activity help build stable aggregate and soil structure.  increased aggregate stability prevents the pore spaces between the aggregates from collapsing during heavy, saturating rains and reduces compaction. 

Improving Yields

EM works firstly through effective organic matter recycling which builds humus, the food for your soil and plants. It will also enhance fertiliser and nutrient breakdown in the soil and uptake by plants, will give improvements in nitrogen fixation and stimulate micorrhyzal activity. 

This has two main functions, firstly it creates better growing conditions and this leads to a stronger healthier plant. Secondly it provides competitive exclusion, which means that it out-competes pathogens for space, by inoculating the leaf surfaces with beneficial microbes. The cumulative effect of all of these functions is a higher yielding crop. 

The graphs on the right show the impact EM can have on yield. 


Pasture Renovation

The below picture illustrates a trial we ran with a farmer showing the effectiveness of EM in pasture renovation. The farmer used a double spray technique with roundup to kill old pasture and then direct drilled new pasture. EM was combined with the Roundup spray at 10 Litres/Ha of EM Ready to Use (RTU). The farmer did one block with EM and one without and the below photos were taken 3 months after emergence. 


Improved Root Structure

This was shows the difference between a paddock of clover treated with EM and one without. The main differences and the improved root structure and many nodules on the treated paddock. There was also a much better breakdown of organic matter in the soil . 

Key applications for Pastoral farming 

  • For large scale use we recommend using our EM Ready to Use product.
  • This is our expanded product and is the most cost effective way to use EM. It can cost as low as $1 per litre for more details contact EMNZ
  • We recommend using 15-20L per hectare when using EM by itself or 10L per hectare when used in conjunction with other nutrients.

A test was done on the height of barley when using regular control versus control mixed with EM

Low Cost Bio-Stimulant

For large scale use we recommend using our EM Soil and Crop product. This is our expanded ready to use product and is the most cost effective way to use EM. It can cost as low as $2 per litre depending on volume purchased (please contact us for volumes in excess of 200 litres). We recommend using 15-20L per hectare when using EM by itself or 5-10L per hectare when used in conjunction with other nutrients.

Please contact us for more information on how to make EM as cost effective as possible.

Soil Matters - Fertiliser Consultancy Interview

In this interview with Rob Flynn, Managing Director of Soil Matters. Soil Matters is a soil consultancy business based out of Canterbury but servicing NZ. They focus on utilising biological nutrients to enhance crop yields and animal performance. We have begun working with Soil Matters providing their customers with EM to further enhance the quality nutrient program they are implementing.

EM's Impact with Nitrogen

EM as a standalone inoculant enhances N fixation in the soil and N production through the recycling of soil nutrients and organic matter. Another way EM can enhance N in your crops is through increasing the response of Urea.

Enhancing Drought Recovery

Many in New Zealand have experienced drought this past summer. Drought is frequently responsible for reduced plant growth and both roots and aerial plant parts may be impacted. Ensuring that plants bounce back strongly following a climate event like a drought is very important but often easier said than done.
