« For 40 years, Scientific research has showed that high quality « living » in compost, rich and balanced in various populations of microorganisms has the power to regenerate soil life, its structure, fertility, as well as its resilience to climate change. Plant’s auto-immune system is present in the soil, and its health is a key factor to protect the plants against pathogenic and disease causing organisms; One aspect for which market products become less cost-effective and inefficient in the long-term. Our laboratory analysis provide producers with a global view over the micro fauna present in their soil and over the progress made using regenerative methods developed together on their land. »

Marc Derelle

Engineer

producer of high quality soil amendements

"For 11 years I have led projects for international corporations and governments in Asia and Australia. I like to support growers managing their soil's fertility, whether it is by running lab experiments for them or to produce tailored soil amendements. Their field experience is very valuable. Our task is to accompany them with our scientific practices towards greater autonomy, profitability and resilience to climate change."

We provide onsite and in-laboratory services

We carry out a diagnosis of the key microorganisms that form the microbiota of your soil, composts and organic amendments.
  • fungi to bacteria ratio
  • nematodes, protozoa
  • parasites, pathogenic microorganisms
  • aerobes/anaerobes
  • % organic matter, pH, nitrates, EC.

Why to assess the microbiota of your soil?

Because the right populations of microorganisms

plays a key role in the immunity and the nutrition of your plants.

MICROBIAL BALANCE

High quality organic soil amendements 

A good soil amendement produces habitats and nutrition for microorganisms to thrive in soil and produce sufficient minerals for your crops, with no need of chemical fertilizer.

 

Our soil amendements are the products of cultures of beneficial microorganisms, balanced in bacteria and fungi with the right amount of natural sources of carbon and nitrogen for them to repopulate your soil and to nourish your crops.

Each batch is monitored in our laboratory and come with its own biological report.

Mise en qualité de composts
Compostage de biodéchets

Pour les collectivités et les industriels, nous améliorons la qualité des composts par des procédés microbiologiques :

  • diagnostic biologiques des composts

  • amélioration de la qualité agronomique des produits finaux

  • suppression des odeurs

  • suppression des pathogènes

  • gestion de la montée en température

  • conservation et minéralisation de l'azote

Activated aerated compost teas and extracts
for large scale lands

Compost extract is a liquid amendement enriched in food for microorganisme to repopulate the soil.

 

Compost tea and extracts are an extraction of beneficial microorganisms En pulvérisation foliaire à raison de 250L/Ha, le thé de compost est un biocontrôle naturel de haute qualité.

Il permet de former une "couche" protectrice et une défense immunitaire contre le maladies et pathogènes extérieurs.

 

Nous produisons le thé de compost"frais" sur site, pouvant être enrichis en minéraux, extraits végétaux et fongiques naturels selon les cultures.

Our workshops

We host practical workshops onsite for farmers, technical consultants and territorial collectivities to observe and regenerate the microbial activity in the soil.

Crop health mirrors soil health

  • pests & diseases

  • weeds

  • loss of nutrients 

  • compactions

  • leaching

  • organic matter < 3%

  • floods

  • and many others

So, how does biological regeneration

  • High quality compost tea sprayed on a plot of large pasture.

  • +6 grazing on the regenerated plot whereas only one on the next plot using in conventional practices.

  • grass richer in protein et minerals.

  • veterinary costs drastically reduced.

What are the benefits for producers?

Reduce your costs
in fertilizers

By enriching the entire chain of microorganisms, their droppings rich in soluble minerals increase in a few months the abundance of nutrients assimilable by plants.

Example:

VS compostbiologically complete (zero fertilizer)

Adventices
Reduce nitrates and weeds sustainably

90% of weeds grow thanks to nitrates; less nitrate, less weeds.

 

By rebalancing your soil in mushrooms, their work is reduced drastically and quickly the nitrates and therefore the work of weeding.

Champignons
Store water in the ground
and reduce leaching

By providing compost rich in a variety of microorganisms, all of the macro-fauna quickly returns to restructure the soil: insects, earthworms, etc. whatquickly reduces erosion and compactionsleaching factors, and significantly increases water retention.

Keep organic matter deep

By spreading a biologically complete compost we bring organic matter rich in minerals but also the complete chain of microorganisms to continuemineralization and deep root development.

Protect against disease

By spraying a liquid compost tea made on your property,it strengthens the protective layer of microorganisms competing with parasitesthroughout the growth of leaves and buds, and reduces treatment costs, even in conventional.

Let's give it a try!

10m x 10m is enough to see the difference

The first practical phase consists of trying several composting recipes slightly varied in fungi and bacteria.

 

We then select the recipe that gives the best results for the production of the liquid compost that will be applied to the rest of the crop.
