An Invitation to Farmers and Other Vetiver Users
Choose Your Path, Document Your Journey, Share Your Knowledge
What if the greatest agricultural research wasn’t happening in laboratories, but on your farm? What if farmers like you—working the land, observing the seasons, feeling the soil between your fingers—held the key to unlocking solutions that scientists need to document and the world needs to see?
That’s exactly what’s happening with the Vetiver System. Around the world, farmers (and gardeners) are discovering that this remarkable grass does far more than prevent erosion. It rebuilds exhausted soil, suppresses devastating pests, conserves precious water during droughts, and transforms struggling farms into thriving operations. Users are documenting and sharing their experiences, some of which have had important impact on other users. You’re invited to join this global ” user research” movement—not as a passive participant, but as a farmer-researcher.
Why Your Farm Is a Research Station
The Vetiver Network International has developed six distinct farm models—six different ways to configure vetiver grass on your land. Some are proven globally across many countries over the past 40 years. Others are newer configurations that make logical sense based on how vetiver works. Early adopters report excellent results, but these models haven neither been fully implemented nor formally documented with scientific rigor.
This is where you come in. Your observations matter. When you notice that tomatoes grown near vetiver hedges have fewer nematode problems than those farther away, that’s data. When you measure your maize harvest and discover it’s 40% higher after establishing vetiver, that’s research. When you observe that your soil stays moist longer during the dry season, that’s evidence. Some of our farmer reviewers find the models interesting and like the implementation rigor that the models support.
You don’t need a degree in agronomy. You need to be a good observer and a willingness to record what you observe, basic measurements of crop yields and pest counts, notes on what works and what doesn’t, and honest reporting of successes and failures alike. Your farm becomes a living laboratory. Your daily work becomes research, and should make your life more interesting. Your experience becomes knowledge that helps other farmers (especially those in your community) to choose the right path and avoid costly mistakes.
Six Paths, One Grass, Limitless Potential
For decades, farmers worldwide have used vetiver grass in various ways—some following traditional contour hedgerows, others experimenting with different configurations based on intuition or local adaptation. Many have achieved remarkable results without fully understanding why vetiver works so powerfully or realizing the full spectrum of benefits hidden beneath the surface.
Today marks something new: the formal launch of six scientifically-structured Vetiver System farm models. These aren’t arbitrary configurations. Each model represents a specific strategic deployment of vetiver designed to deliver distinct benefits—from basic erosion control to complete soil transformation to long-term climate resilience. Some have 40+ years of global validation. Others synthesize emerging research on mycorrhizal networks, nematode suppression, and beneficial insect ecology into practical farming systems that early adopters are proving successful but that need your documentation to validate fully. All can be modified as we learn more about them.
Before choosing your model, read these two essential documents:

Here is a quick orientation to the six models:
V101 Standard—The Foundation: Permanent hedgerows on contour lines at 2-meter vertical intervals (3,500 plants/ha). The simplest, most proven system—tested in many tropical countries over 40 years. Excellent water management and erosion control.. Documented water behavior changes, soil moisture differences, and crop performance 1-2 meters from hedges versus farther away.
V101-E Enhanced—Complete Field Coverage: V101 hedges plus individual vetiver plants in a 4-6 meter grid (4,125-4,550 plants/ha total). Creates field-wide mycorrhizal networks—invisible underground partnerships that help all crops access water and nutrients. Suppresses plant-parasitic nematodes across your entire field, not just near hedges. This model needs your documentation—early results are promising but formal validation is incomplete.
V48 Intensive—Maximum Impact: Dense hedgerows every 4-8 meters horizontally (7,500-15,000 plants/ha). Field-wide pest suppression (70-90%), measurable temperature reduction (1-3°C), substantial mulch production (8-18 tons/ha yearly). Creates permanent habitat for beneficial insects. Documented 50-80% yield improvements.
VCR Rotation—Complete Transformation: V101 hedges plus intensive 3-year vetiver rotations through farm quarters (11,750 plants/ha in rotation sections). Produces 80-130 tons organic matter per cycle, eliminates nematodes (90-95%), and rebuilds devastated soil. For severely degraded land or ASAL livestock operations. Yield improvement: 80-150%. This model needs farmer-researcher documentation.
VFF Food Forest—Climate Resilience: Vetiver as living carpet under fruit trees and agroforestry systems (25,000-30,000 plants/ha initially). Temperature reductions of 7-10°C, massive carbon sequestration (71 tons CO₂/ha), exceptional drought resilience. Vetiver thins naturally 40-60% as tree canopy matures over 10-20 years. Long-term farmer-researchers needed.
VPGS Plantation Grid—Retrofitting Existing Orchards: Infrastructure hedges plus 6×6 meter grid between existing crop rows (6,000-9,000 plants/ha). For established coffee, tea, citrus, avocado plantations/orchards where contour hedgerows can’t be retrofitted. Creates beneficial insect corridors for pest control while providing complete mycorrhizal coverage.
What Should You Record?
Research doesn’t require expensive equipment. A notebook, measuring tape, (a soil moisture meter can be pretty handy) and attention to detail generate valuable data:
Before planting: Current crop yields, pest problems, fertilizer/pesticide use and costs, labor days, erosion observations, soil condition photos.
During establishment: Planting date, number of slips, spacing pattern, whether you used mandatory dip treatment (critical!), survival rate after 8 weeks, challenges faced.
Ongoing (Years 1-3): Water behavior changes, soil moisture patterns, crop yields from same areas as baseline, pest and disease pressure, input use changes, temperature differences, beneficial insect observations, drought resilience.
Economic data: Total costs, income changes, input savings, labor requirements, payback period.
Partner with Local Agricultural Professionals
Don’t document alone. Invite your local agricultural extension officer or agronomist to collaborate. Offer them real-world field data from your working farm—more valuable than controlled experiments. They can provide soil testing, technical guidance, measurement protocols, and credibility. You maintain the system and do daily observations; they provide professional support and testing facilities. Your farm becomes a demonstration site. Their reports and training materials use your data. Both benefit from credible, field-validated research.
Start with a simple invitation: “I’m establishing a vetiver system and plan to document results carefully. Would you help with soil testing and measurements? This could give you field data from a real farm under typical conditions.”
The Non-Negotiables
These systems depend on three critical factors:
Mandatory Dip Treatment: Every slip must be dipped in microbial solution (AMF and beneficial bacteria) before planting. Without this, establishment mortality can jump from 2% to 50%, particularly in hot, dry, and degraded soil situations, establishment time can double, and mycorrhizal networks fail to form properly (these networks help transport nutrients and moisture to adjacent crops).
Accurate Contouring: Hedges must follow true contour lines within ±2 degrees. Water flows laterally along hedges spreading water, improving infiltration and reducing erosion.
Aggressive Early Weeding: Weed weekly around young plants for weeks 1-8. Competition during establishment kills more vetiver than drought, pests, or poor soil combined.
Join the Movement
Imagine five years from now. Your farm transformed. Your soil darker, richer, more alive. Your crops surviving droughts that devastate neighbors. Your yields climbing while fertilizer bills fall. But more importantly, you have knowledge.
You understand the timeline, the challenges, the solutions. You have notebooks filled with observations, yield records showing improvements, economic calculations proving the investment paid off. You have credibility. Other farmers come to you. You become a teacher, sharing proven local evidence.
The Vetiver Network International and your country needs farmer-researchers like you in every agricultural region. The six models provide the framework, but you provide the ground truth. Your observations refine recommendations. Your measurements validate projected benefits. Your economic data helps others make informed decisions.
You’re not volunteering for someone else’s research—you’re investing in your farm while generating knowledge that makes you a local expert. The data you collect serves your decision-making. The documentation you create builds your credibility. The transformation you achieve becomes a demonstration site neighbors can see.
Choose your model. Plant with care, using mandatory dip treatment and proper contouring. Observe carefully. Record honestly. Share generously. Join a global community proving that degraded land can be restored, that farming can be both productive and sustainable, and that agricultural knowledge often comes from farmers willing to experiment, document, and teach. Especially work with and for the betterment of your local community.
Remember you don’t have to commit your whole farm – you can if you want just start on a small area and then expand as you gain confidence.
Your farm is your laboratory. Your observations are your data. Your transformation is your research. Welcome to the movement.
