A new device developed by a team of Lithuanian and Spanish researchers allows detection of the alteration produced by drought on certain key parameters of the plant's physiological state
Among weather events, in the Netherlands, drought reduced yield by 24% compared to the average, rain during sowing lowered it by 18%. Photo: Paul van de Velde Attribution 2.0 Generic CC BY 2.0 DeedPaul van de Velde Attribution 2.0 Generic CC BY 2.0 Deed

Two Dutch studies reveal the impact of weather on crop yields

,
The reduction in crop yields following extreme weather events such as drought and heavy rain has been accurately quantified for the first time. Depending on the type of crop and the phenomenon, the decrease ranges between 13 and 36%.
In acidic soils such as red clay soils, the use of rock dust for CO2 capture produces disappointing results.

Rock dust helps capture CO2 but not in acidic soils

,
The dispersion of rock dust in the soil is generally an effective way of storing carbon. But in acidic soils, according to an Australian study, this mechanism does not work
