Sown after the corn harvest, oat or rye coverings do not always have time to develop and capture little residual nitrogen. Seedlings of RGI-clover growing in maize serve the purpose of covering the soil but are difficult to remove. Seeding tests using the forage harvester will be carried out this year at the Kerguéhénnec experimental station. The drone, by its ease of intervention, before harvesting, has its card to play. It has already proven its worth on the application of trichogramma (against the European corn borer) and phytosanitary products, with booms. He must prove his ability to sow homogeneously.

The majority of the seeds should reach the ground. Measures carried out ...
