Installation of sensors for precision crop nutrition

To measure the availability of nitrogen (N) and potassium (K), RMA also installs nutrient sensors this growing season. The aim of the setup is to use the fertilizers N and K as economical and useful as possible. And don’t forget that precision nutrition contributes to maximum crop quality. RMA measures nutrients in potatoes, onions and flower bulbs such as lilies and gladioli.

LoRa data loggers are installed in the fields of the participating farms that continuously measure the moisture and nutrient content in the soil. The growers can use the smart dashboard to determine whether and when irrigate and what the effect will be on the nutrients in the soil. The nutrient sensors are manually calibrated by regularly absorbing moisture from the soil and analyzing this with a speed tester.

The project of installation of sensors for precision crop nutrition is made possible in part by the Future-oriented Agriculture scheme of the Province of Drenthe.

Start demonstration project to improve irrigation in Poland

The Dutch companies RMA, Loonstra & van der Weide, Irriwatch and the Polish farm Cena are starting a cooperation project in Poland.

In the project, the techniques of soil scans, sensors and satellite images come together. What we do during the growing season is to compare the advices for different irrigation techniques such as drip tape, pivot and reel. This gives us insight into the possible savings and yield increases. The Polish growers are very interested after the very dry years of 2018 and 2019.

The project is partly supported by a contribution from the subsidy scheme for demonstration projects, feasibility studies and investment preparation projects (DHI) of the Netherlands Enterprise Agency (RVO)).

From flooded fields to agricultural drought

From floods to drought in a very short time: many farmers have already starting irrigating again. But what is the best timing and how much water should be applied?

Irrigation management contributes to profitable and sustianable crops. RMA supports growers with novel sensors, a smart dash dashboard and expert guidance. Read more about our approach in this brochure.

RMA has 25 years of experience and can be characterized by a personal way of working and a no-nonsense approach. Our methodology not only ensures confidence in the technology, but above all the human aspect in it.

Nutrient sensors adjust nutrition to crop demand

Nutrient sensors continuously measure the concentration of minerals in the soils. “The readings will help growers to adjust their fertilizer application rate and timing to match with what the crop exactly needs.”, says Peter Raatjes, director of RMA. In an article in Dutch agricultural magazine ‘de Boerderij’ Peter explains that the effect of irrigation on concentration of nitrate and potassium in the soil available water can really be measured.

Introducing our new colleague

RMA is growing. We will expand our team with Bas Hengst on 1 March 2020 in the position of Field Service Engineer.

Bas will be responsible for the installation and maintenance of telemetry and sensor systems at our customers. The intention is that the United Kingdom becomes an important area of ​​attention for Bas. RMA recently concluded a service contract here for a large weather station network.

Bas has experience in agriculture and he knows what he is talking about when speaking about technical installations. Bas gained experience with crop growing in Australia and worked in South Africa as a product specialist for water quality sensors and data loggers.

“I am looking forward to working at RMA, gladly roll up my sleeves and take this opportunity in precision agriculture with enthusiasm,” says Bas. Preparations for his arrival are now in full swing. We wish Bas every success with RMA!

A wonderful 2020

Between Christmas and New Year it is the time to reflect on the year gone by and look out into the year to come.

The highlights of 2019 in a nutshell: being awarded the Adcon Distributor of the Year award, extension of our dashboard with weather forecast, introduction of nutrient sensors to growers in the Netherlands and the successful organisation of our first international conference in Dwingeloo.

For 2020 many exciting new developments are being lined up. From demonstrations with growers till new product developments for an even wider application of our products and services.

The New Year will kick off with an expansion of the team: Wendy van Barneveld will join the company as coordinator business operations and take care of organisational and administrative matters.

A big thank you for all our clients and partners for their trust of RMA. In 2020 will do our utmost to be successful together once again. Wishing you all the best for a wonderful 2020!

International conference in Dwingeloo very successful

On August 29 and 30 RMA organised her first international conference. A group of 25 delegates travelled from the Netherlands and abroad to Dwingeloo to exchange information and ideas on sensortechnology, sustainable agricultural watermanagement, drip irrigation, fertigation and precision agriculture. On the 29th a range of presenters shared experiences from their country and application followed by lively discussions at Hotel Wesseling in Dwingeloo. On the 30th a field visit was made to see the RMA sensor technology live in action in the province of Drenthe.

Jorg Tönjes wrote a report on the meeting which can be found at Akkerwijzer.nl (in Dutch).

Sensors manage soil moisture well despite extreme temperatures

Extremely high temperatures in the Netherlands over the past week with five days over 30 degrees and an all-time high of 38,9 measured at our RMA weather station. Despite the harsh conditions our sensors were able to help the growers to manage their soil moisture levels well without getting into drought stress.  The examples below show that both the trickle tape (left) and the rain gun (right)  were able to maintain the readings in the safe, green zone.
