The scientific fields of tillage, crop production and the related soil science, agro-chemistry, agro-meteorology, plant physiology and engineering have undergone major changes in the last four decades. These changes primarily revolve around the practical application of scientific results. Long-term experiments are of national and even international value. The importance of long-term experiments was particularly appreciated in the development of precision agriculture. Long-term experiments serve to scientifically substantiate important goals such as adaptation to climate change, its promotion in land use, crop production and the development of environmentally friendly, sustainable production technologies, and the complex study of the long-term biological, agronomic and economic efficiency of cultivation. The long-term field experiments at the Faculty of Agricultural and Food Sciences and Environmental Management of the University of Debrecen were established in 1983 at the Látókép Experiment Site. Field experiments in Debrecen provide excellent foundations for environmentally friendly sustainable land use, crop production, development of production techniques, tillage, irrigation, fertilisation, variety and hybrids selection.
