ILVO’s fertiliser spreader calibration lab offers services to farmers, fertiliser spreader manufacturers, and fertiliser-producing companies. Two different approaches are used for assessing the performance of centrifugal and pendulum fertiliser spreaders for specific types of fertilisers: collection trays equipped with anti-reflection grids are used for determining spread patterns in field conditions.
The ILVO testing field is a small field with dry sandy loam soil. The testing field is conveniently located next to our workshop facility, allowing us to test and adapt a prototype in quick succession in a real-world setting. Depending on the intended tests, different crops are installed each growing season.
The CEMOB Bench is dedicated to enhancing the efficiency of spreading processes by optimising both machines and products, such as granules and compost. The CEMOB research bench accurately measures and characterises spreader sheets using traditional transverse measurement methods. The 3D measurements enable detailed analysis of spreading performance, including mapping ground distribution and assessing homogeneity. CEMOB also allows the evaluation of a product’s suitability for wide-area spreading and the impact of optimised spreading devices.
The CEMIB rotating test bench, patented by INRAE, is a high-performance device for measuring the distribution of granular products (fertilisers). It enables quick, reliable, and cost-effective evaluation of spreading patterns. CEMIB scans the spread pattern, angular sector by angular sector, using around 90 sensors recorded at 10 Hz by a synchronous system. It provides precise, disturbance-free measurements of fertiliser distribution in grams/m² and reliable data on projection range and angles.
The experimental plots to study machine-soil interaction offer advanced tools to study machine-soil interactions. The MONROE system measures the efficiency of agricultural tires and machines, assessing traction and soil compaction under various conditions, including tire type, pressure, and soil characteristics. It uses constant torque and traction force methods alongside additional measurements of effort, torque, angular velocity, and actual speed. The SoilXplorer tool provides electromagnetic response maps of soil, based on texture and moisture levels.
The experimental plots for alternative weed control consist of a 4-hectare field, with additional areas available. Depending on the experimental needs, the site is equipped with advanced technology for data capture of soil and plants, an electric power supply using an electric generator for the computer units and charging for electric weeding solutions, as well as remote monitoring of crops and the environment via wireless sensors and a field meteorological station.
The Off-road vehicle and robot mobility tracks in Allier (France) feature advanced testing infrastructure developed by INRAE-TSCF-AGROTECHNOPÔLE for mobile machines and vehicles. The facility offers numerous accessories, including obstacles like mannequins and natural or artificial hedges. The cross-shaped track allows testing from various cardinal points and orientations relative to the sun. Additionally, the inclined profiles enable testing of agricultural machinery on different slope gradients.
Located within a network of real-world testing and validation environments, this facility facilitates collaboration between technological SMEs and agricultural experts. It serves as a platform for developing cutting-edge solutions tailored to address specific challenges in the sector. The space supports businesses by bridging the gap with expert advice, specialist training, and networking opportunities, ensuring innovative ideas are rigorously tested and refined.
It excels in soil and crop characterisation through advanced 3D mapping and field scanning techniques. The lab employs a variety of sensors and imaging tools to assess vegetation health and soil conditions, enabling precise measurements of geometric and structural parameters. Key features include remote sensing drones for aerial imaging, precision phytosanitary applicators, and variable-rate sprayers designed to optimise fertiliser and pesticide application.
