The goal was to see how nutrient deficiencies affect soil fertility and harvest yields in sandy soils. In 1949, long-term field experiment D4 was split into two subfields: D41 and D42. Due to their different treatments, the datasets for these two subfields are available separately.\nD41 has maintained the same treatments since the beginning of the experiment, reducing the number to four replicates in 1949, so that D42 could be given an alternate treatment (further information in the field description for D42 https://doi.org/10.20387/bonares-eprk-bj95). \nSince 1957, the crop rotation has been potatoes - spring barley - silage corn \u2013 spring barley. In 1959 the accumulation of nematodes led to the decision to include silo corn (previously not farmed) to be included in the crop rotation extending the period between potato seasons to three years. The crop rotation continued afterwards according to the original plan.\nThe harvest plots in the geodata represent the standard harvest plots for root crops and grains, which have maintained their size since 2000 (excluding in 2018).

The experimental site was founded in 1936 by Prof. Kurt Opitz is located about 30 kilometres south of Berlin. This site represents typical farming conditions of the young moraine landscapes of the Weichselian glaciation of Northeast Germany. According to the German classification of soil-climate spaces, the experimental site is located in the area of \u201cdry-warm diluvial soils of East German lowlands\u201d (diluvial: soils developed in glacial sediments). Within this area, soil values of the \u201cGerman soil taxation framework\u201d of less than 30 out of a maximum 100 are common.\nThyrow is located at approximately 42 m above sea level on the southern edge of the Teltow, a Weichselian ground moraine plateau. The slope is predominantly flat at 2 %. The dominant soil type for this is location is a Retisol developed in a sand over a deep loam. As typical for ground moraines the boundaries between the sandy and loamy layer vary intensely between 60 cm to 200 cm. This causes small-scale differences in water and nutrient resources especially of the subsoil. The plant available water capacity of the soil in the effective root zone (60 \u2013 80 cm deep) fluctuates between 50 to 150 mm. These soils are at high risk of nutrient leaching, acidification and surface siltation because of the low clay and humus content of the topsoil.\nDue to the soil\u2019s low water-holding capacity, the crop yields at the Thyrow Field Station show great fluctuations dependent on weather conditions. The climatic water balance during the growing period is negative and the overall low water availability at this location limits the crop yields. Mean annual temperature for the period 1991-2020 was measured to be 9.7\u00b0C, with annual precipitation 533 mm. Annual crop yields are particularly negatively affected by low precipitation from April to June.\nThe two areas that are managed by the research station are separated by the Thyrower Dorfstra\u00dfe (Landesstra\u00dfe 795). The main experimental area, where the long-term experiments are conducted, is located on the farm (Hof) side, along with two other trials for the implementation of field experiments. Northwest of the Landesstra\u00dfe there is another experimental area (Schlag 3), where other experiments are conducted to answer questions about differing agricultural systems, soil management, cultivar suitability, and fertilization.\n\nSoil classes according to German Soil Taxation: \tS4D, Sl5D, Sl4D\nSoil textural class: \tsilty sand\nMean annual temperature: 9.7\u00b0C (1991-2020) / 9.2
