New systems are set at the services of agriculture. At the conclude of August, a drone vegetation protect take a look at was analyzed on a cornfield.

In purchase to preserve the fields between the crops, a person procedure consists in rising grass there. This lets, among the other items, to restrict the loss of nitrogen, to stimulate organic activity and to protect soil erosion throughout the wintertime.

Problem: in the circumstance of maize in unique, the crops are produced in Oct, a period of time with a local weather not favorable to the shoot. It&#39s not a extensive time back, and the agronomists considered to fix the dilemma by anticipating the seed of a handful of weeks, right before the harvest, to let time for the germs to occur out of the earth, getting gain of the very last rays of sunshine of the summer season and the irrigation of maize, devoid of competing with its development.

For sowing right before harvest, farmers use straddling or helicopters, but the to start with have the fault of damaging the soil, the next not to distribute the seeds evenly in the fields. The answer could then occur from drones. In purchase to answer these queries, tests ended up carried out on a corn subject in the commune of L&#39Isle-de-Noé, in Gers, at the conclude of August.

Ultimate success expected in March

It will get some time right before we know if the take a look at has been reworked, but a dozen days afterwards, the to start with conclusions are promising. “The cover has germinated in a homogeneous way,” claims Stéphane Ballas, task manager at Ovalie Innovation, a subsidiary of the two agricultural cooperative teams Vivadour and Maïsadour. It will be essential to wait around to see how the grass resists at the time of the harvest, then throughout the wintertime. The conclusions will be produced in March when the maize cycle resumes. “

Meanwhile, the time is to the fulfillment of the Reflet du Monde, the enterprise primarily based in Mérignac and specializing in drones, who collaborated on the task: “We had predicted, but items ended up performed promptly , in fewer than a few months, simply because we had to be all set by the conclude of August, claims Patrice Rosier, co-founder and co-manager of the SME. It was essential to be exact so that the distribution of the seeds does perfectly, with constraints of embedded mass. We are content with the result. “


Eco-friendly and useful

The seeds are dropped to 15 meters of the ground on a diameter of twelve meters. The drone weighs twelve kg, with a load of 4 kg of seeds on board, for which the refill is produced in “fewer than a person minute”. Many hundred hectares of subject can be protected for every day by a solitary drone, electric powered, thus fewer polluting than an agricultural equipment or a helicopter. Its use only mobilizes a person human being throughout a typical operating day (2×4 several hours).
