Discover how Effective Microorganisms™ (EM™) are helping vineyards across New Zealand achieve healthier soil, stronger vines, and sustainable, chemical-free yields.
The Future of Viticulture Is Microbial
New Zealand’s vineyards are world-renowned for producing exceptional wines — but behind every premium harvest is a healthy, resilient vineyard. As growers face challenges like soil degradation, pest pressure, and the need to reduce chemical inputs, Effective Microorganisms™ (EM™) technology has become a trusted ally.
EM™ is more than a product — it’s a powerful, natural solution supporting organic vineyard management and delivering results that modern viticulturists can count on.
What Is EM™ and Why Does It Matter for Vineyards?
EM™ (Effective Microorganisms) is a proprietary blend of beneficial microbes, including lactic acid bacteria, yeasts, photosynthetic bacteria, and fungi. Together, they work to:
-
Improve microbial soil health
-
Boost nutrient cycling and eco-friendly plant nutrition
-
Enhance vine immunity and suppress pests
-
Break down organic matter into plant-available nutrients
- Improve soil structure and water retention
For vineyards aiming to increase sustainability and crop quality, EM™ is a valuable tool for both certified organic farming and sustainable viticulture practices.
Key Benefits of EM™ in Viticulture
Enhancing Soil Biology
EM™ stimulates soil microbial activity enhancement, boosting microbial diversity and supporting healthy soil microorganisms. This leads to improved root growth, better nutrient uptake, and resilient vines — all while improving soil structure naturally.
Breaking Down Organic Matter Efficiently
By accelerating the decomposition of cover crops, prunings, and compost, EM™ promotes natural waste decomposition and produces valuable organic acids. This not only recycles nutrients but also builds long-term soil fertility.
Boosting Fertiliser Efficiency
EM™ microbes solubilise organic and inorganic compounds that are often locked away in the soil, making nutrients more available to the vines. Many growers report being able to reduce fertiliser use while maintaining or even increasing vineyard yield naturally.
Fungi and Mycorrhizae Stimulation
EM™ enhances beneficial soil fungi populations, including Mycorrhizae and Trichoderma, which further improve nutrient uptake and root health.
Plant Protection and Disease Suppression
EM™ acts as a biological crop protectant. By introducing beneficial microbes to soil and plant surfaces, EM™ uses competitive exclusion to suppress harmful pathogens and pests — offering natural pest control for crops without synthetic chemicals.
Versatile, Sustainable Applications
EM™ can be:
-
Applied to soil to stimulate natural processes
-
Sprayed on foliage to populate vines with beneficial microbes
-
Integrated into composting and waste management in agriculture
-
Used to treat wastewater and control odours
-
Applied during disease pressure periods to strengthen vines and outcompete pathogens
Eco-Friendly, Cost-Effective, and Certified
EM™ is BioGro certified and offers a low-cost, multi-purpose solution. It aligns perfectly with eco-friendly farming solutions, helping growers meet sustainability goals while reducing input costs and improving crop resilience.
Real-World Results for Vineyards
New Zealand viticulturists using EM™ consistently report:
-
Healthier soils with greater microbial diversity
-
Stronger root systems and thicker grape skins
-
Improved canopy density and water use efficiency
-
Increased resilience against pests and diseases
- Higher quality yields with reduced chemical input
Whether you're focused on small-scale sustainable home gardening or managing a large commercial vineyard, EM™ offers scalable solutions for improving organic crop yields and soil health.
A Smarter, Natural Future for Viticulture
As the demand for sustainable agriculture products and organic viticulture solutions continues to grow, more New Zealand vineyards are choosing EM™. By working with nature — rather than against it — EM™ supports sustainable crop productivity while protecting the environment for future generations.
