Sugar beet time series experiment (V465) for collecting holistic data for modeling (1972, Bad Lauchstädt, Germany)

To create a holistic data set for the verification of sugar beet yield models, a time series field experiment was set up in 1972 in Bad Lauchstädt (Germany), a location in the Hallensian Börde Plateau with loess soils up to 1,5 m depth, which is predestined for sugar beet cultivation. The soil is divided into horizons as follows: Arable topsoil (up to 25 cm depth), humic lime-free horizon (up to 40 cm depth), calcareous mixed horizon (up to 60 cm depth) and calcareous loess (up to 125 cm depth). In a block design experiment with four replicates, the test factors irrigation with two levels and fertilization with three levels were studied. Intensive holistic data collection on the most important plant and soil parameters was carried out at weekly intervals until final harvest at the end of September. In the case of sugar beet plant, the fresh and dry biomasses of the leaf and the body and some plant contents such as nitrogen, phosphorus, potassium, magnesium, calcium and sodium contents as well as sugar and ash contents were measured or determined. In addition some ontogenesis and stand density parameters were observed. Soil parameters such as nitrogen, soil water, pH as well as phosphorus, potassium, magnesium and sodium contents were measured for two 25 cm soil layers up to a soil depth of 0.5 m. The meteorological variables temperature and precipitation were registered to a daily accuracy and aggregated to monthly values. All agro-technical measures are presented in detail.
