Applying UAV-based crop height to monitor biomass, N-concentration, and N-uptake in winter wheat

The TephAta database collects information on volcanic ash layers from the Atacama Desert, including their physical properties, geochemical composition, and age. The dataset provides a basis for identifying the same volcanic ash layers in different sediment deposits making it possible to link and date sediments It also supports studying how ash spread and understanding the region’s volcanic past.

Leaf water potential was at certain thresholds, depending on soil type, water treatment, and weather conditions. In rainfed plots, the lower water availability in the stony soil resulted in fewer roots with a higher root tissue conductance than the silty soil. In the silty soil, higher stress in the rainfed soil led to more roots with a lower root tissue conductance than in the irrigated plot. Crop responses to water stress can be opposite, depending on soil water conditions that are compared.
