Innovative technology in arable farming systems
On the part of practical agriculture, there is the question of how innovative seeding, tillage and fertilization methods may further contribute to optimize the nitrogen utilization by North German agricultural systems. In particular, for cash crop farms who want to take farm manure from surplus regions, innovations in tillage, seed and fertilizer technology are in demand. There is already experience with individual procedures in other regions of Europe, but they have not been tested or verified in SH. On a sample representative of SH arable land, the OG intends with the help of demonstration trials to examine new techniques in practical operation (normal drilling, precision drilling, strip tilling and fertilization, combination of strip tilling + precision drilling). The objectives are as follows: Stabilization of crop yields, increased N-use- efficiency in arable farming systems, increased nutrient utilization rate for farmyard manure, protection of groundwater by reducing N leaching, protection against wind and water erosion, improved GHG balances in arable farming systems, improved efficiency in water and nutrient use and optimizing costs.
Due to the extreme weather events in the project years, the original project idea could not be fully implemented. The results do not show a clear advantage in favour of a particular sowing technique or fertilization strategy in terms of the yield achieved.
A key finding from the project is the great importance of the time factor for the sowing date. Under the conditions of extreme weather (especially in 2017 and 2018), the trials have shown that seeding methods are hardly feasible in practice in Schleswig-Holstein. They double the working time required and therefore stand in the way of timely fall tillage - especially in years with narrow weather windows.
Particularly on farms with large areas, this would require a significantly higher machine capacity, which is not justifiable from an economic point of view.
