Long-Term Comparison of Organic and Conventional Crop Production Systems (1994–2023) in Osiny, Poland

Long term experiment on comparison of different crop production systems established in 1994. Data compares 2 different farming systems: organic and conventional. Data is available from 1995/1996 season up to 2022/2023 season.The experiment is conducted without replication (8ha in total - 1ha per rotational field). All crops of the rotation within one system are grown at the same time (all crops from the rotation present in the field each year). Size of single rotational field is 1ha. Crop rotation (general design - there are some differences between years)Organic Farming System: Potato xx ; spring wheat + undersown red clover ; red clover 1st year ; red clover 2nd year ; winter wheatConventional Farming System: Oil seed rape; winter wheat ; spring wheatThis dataset is part of the database compiled as an outcome of Work Area 1 in project OrganicYieldsUP.
