Cultivation of soy without land competition through mixed cultivation in wheat and silage maize








  • Potential demand for land in Hesse for the production of soy for feed and food purposes exceeds the current area under soy cultivation many times over; the majority is imported from third countries.
  • High cultivation risk of soy, preference for "safe" crops such as cereals or common grain legumes
  • Due to the scarcity of land, a noticeable increase in soybean acreage would mean a corresponding reduction in the cultivation of other crops.
  • Problem of pigeon damage to soybean seedlings


Planned innovation & aims 


The aim of the project is to develop a cultivation system that increases the cultivation security for soy and does not require any additional land while simultaneously increasing biodiversity.

  • Mixed cultivation of soya in winter wheat and silage maize; soy in addition to the wheat yield from the same area ("on top").
  • Improved utilisation of the growing season and harvesting of the products at different dates ("wide row")
  • Creation of a basis for regional value creation in this area 





  • Procedure implementation and sampling/monitoring, analysis and scientific preparation and presentation.
  • Implementation in practice: Testing of existing technology for the process; formulation of modifications and development requirements compared to agricultural technology in the areas of sowing technology, maintenance technology, harvesting technology.
  • Specification of wheat and soybean varieties: Elaboration and provision of varieties for the detection of the requirements for the procedure mixture partner wheat
  • Communication: creation/maintenance of project homepage, organisation of practical events, coordination of the creation of publications/practical media; networking
  • Agricultural technology: if necessary, bringing in partners from the agricultural technology sector (sowing technology, control, maintenance technology, harvesting technology).
