Roots for the City, for tomorrow

    Young plantations.

Need To boost reliability on your plantation?
The root anchoring of a young plantation determines its success in the medium and long term.

Guide root recovery with appropriate watering


Prepare the manager to take over: you have a tool for sharing information on the evaluation of plant root recovery.

Make your recovery observations more reliable: you can use indicators and quantitative data to prove the root growth of plants.

A step ahead against water stress


Prepare the manager to take over: thanks to the indicators, you can identify high-risk situations almost 14 days before the leaves wither.

Differentiated information in case of difficulty: when a risk for plantations is identified, a dedicated message allows you to be informed instantly.

Easy to use and functional guarantee


Prepare the manager to take over: you’ll receive weekly recommendations in the unit of your choice: millimeter, watering time per sector or as a percentage of a reference program.

The Urbasense team works with you : to ensure set up, maintenance and any repairs on our stations. Our packages include all communication costs for the sensors.

Do not dwell in the past, do not dream of the future, concentrate the mind on the present moment. Never be bullied into silence. Never allow yourself to be made a victim. Accept no one's definition of your life; define yourself. Don't go around saying the world owes you a living. The world owes you nothing. It was here first. If you don't like something, change it. If you can't change it, change your attitude. Change will not come if we wait for some other person or some other time. We are the ones we've been waiting for. We are the change that we seek.

Avant de faire appel à Urbasense, nous arrosions un peu à l’aveugle, de manière non différenciée entre les espèces, sans maîtriser vraiment les quantités apportées. Nous avions une tournée d’arrosage manuelle, avec un passage à la tonne environ toutes les deux semaines. D’une manière globale, nous avions l’impression de trop arroser. Dans la mesure où les signes sont les mêmes lorsque les plantes reçoivent trop d’eau ou en manquent, nous étions en permanence dans l’incertitude

Lorsque j’ai entendu parler pour la première fois de tensiométrie, en 2013, j’ai été tout de suite intéressé. Cette technologie semblait en effet permettre non seulement de diminuer considérablement les volumes d’eau utilisés, mais aussi d’optimiser la reprise des végétaux. Malheureusement à l’époque, notre direction générale des services n’a pas été convaincue par l’outil. Ce n’est qu’en 2016 que les choses ont commencé à bouger. Et pour cause, nous envisagions de mener beaucoup de projets neufs sur la ville, incluant la plantation de gros sujets. Par ailleurs, dans la mesure où la ville d’inscrit depuis 4 ans dans une dynamique d’économie d’eau, l’aspect financier était évidemment important. C’est pourquoi nous avons décidé de faire appel à Urbasense. Notre objectif : éviter les pertes de jeunes sujets et donc d’argent et de temps. Et nous n’avons pas été déçus.

Le suivi tensiométrique nous a permis de diminuer très clairement les programmations d’arrosage : d’un arrosage programmé toutes les deux semaines, nous sommes passés à un arrosage avec la juste quantité d’eau si préconisation. Concernant l’arrosage à la tonne, même si les choses sont un peu plus compliquées, nous observons tout de même un espacement des passages et un arrosage par essence là où nous arrosions tout uniformément. Nous sommes donc convaincus que plus nous aurons de sites équipés, plus nous pourrons affiner nos arrosages à la tonne."

Understanding the service : some details

How long do you follow the new plantations?

For optimal results, the plantations are monitored from the year of completion until sufficient water autonomy is achieved. It is therefore necessary to ensure that the root system is sufficiently developed in depth and outside the root ball.
In practice, monitoring usually lasts between 2 and 3 years.Meaning the first year for completion and one to two years for strengthening, depending on the situation and nature of the plantations.

How are the recommended doses and watering frequencies calculated?

To establish our recommandations, we first rely on the state of development of the root system: roots contained within the root ball require a smaller volume of water than an active root system on the periphery. This is the estimate of the optimal dose of each watering.

For calculating frequency, we first estimate the number of days remaining before the plant enters into water stress. Then we take into account a series of criteria such as its water behaviour, the nature of the soil explored by the roots, the sensitivity of the planting pit to precipitation, or the meteorology to come.

This analysis is summarized and sent each week in a summary email recommending watering.

I already have a take-back guarantee on plantations: what is the point of an additional service?

Because the "take-back guarantee" ensures the replacement of a dead tree by a young tree... which has not taken up again!

At Urbasense, we believe that the best guarantees of a vigorous, resistant and inexpensive plant heritage in the medium and long term are the care and maintenance of the crop. These guarantees are generally provided for planting contracts or by the authorities.

Finally, the administrative tool of the "take-back guarantee" is by nature limited on time compared to the length of tree’s life.

Understanding the equipment : some details

What is the autonomy of your sensors?

It increases every month. Today, it is between 18 and 24 months. In concrete terms, we carry out an annual maintenance that includes a change of batteries.

How do your sensors comunicate?

Several telecommunications technologies are used depending on the availability of networks at each site: GSM, SigFox, LoRA. WiFi and BlueTooth are not used today, for practical and energy reasons.

Are your sensors guaranteed?

Yes, our sensors are guaranteed for the entire duration of the contract when they are rented (global functioning guarantee). They are guaranteed for two years when they are sold.

What is your perspective on the reliability of your sensors?

The first sensors developed at the end of 2014 are still operational in the field. More broadly, we assemble and test all our devices ourselves and we control this assembly line, which is a critical point for sensor reliability.
