Evaluating early‐season hail damage in corn and its interaction with Goss's wilt

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Hailstorm losses are associated with plant defoliation, stand losses, and reduced crop canopy capacity to compete with weeds. Additionally, hail wounds in plants might favor disease development, potentially further reducing corn yields. Corn yield losses due to hailstorms early in the growing season are considered minor due to an expected ...

Unmanned Aerial Vehicles

2021
Last January, the General Secretariat of the Council of the European Union produced an estimate that, by the year 2035, the drones' sector will create up to 100,000 new jobs and, in addition, will have an economic impact of more than ten billion euros per year. This chapter takes its cue precisely from the central importance of unmanned aerial vehicles,
