Abstract Slowing crop yield increases despite high fertiliser application rates, declining soil health and off-site pollution are testimony that many bioproduction systems require innovative nutrient supply strategies. One avenue is a greater contribution of organic compounds as nutrient sources for crops. That plants take up and metabolise organic molecules ('organic nutrients') has been discovered prior to more recent interest with scientific roots reaching far into the 19th century. Research on organic nutrients continued in the early decades of the 20th century, but after two world wars and yield increases achieved with mineral and synthetic fertilisers, a smooth continuation of the research was not to be expected, and we find major gaps in the transmission of methods and knowledge.

Background
Slowing crop yield increases despite high fertiliser application rates, declining soil health and off-site pollution are testimony that many bioproduction systems require innovative nutrient supply strategies. One avenue is a greater contribution of organic compounds as nutrient sources for crops. That plants take up and metabolise organic molecules (‘organic nutrients’) has been discovered prior to more recent interest with scientific roots reaching far into the 19th century. Research on organic nutrients continued in the early decades of the 20th century, but after two world wars and yield increases achieved with mineral and synthetic fertilisers, a smooth continuation of the research was not to be expected, and we find major gaps in the transmission of methods and knowledge.

Scope
Addressing the antagonism of ‘organicists’ and ‘mineralists’ in plant nutrition, we illustrate how the focus of crop nutrition has shifted from organic to inorganic nutrients. We discuss reasons and provide evidence for a role of organic compounds as nutrients and signalling agents.

Conclusion
After decades of focussing on inorganic nutrients, perspectives have greatly widened again. As has occurred before in agricultural history, science has to validate agronomic practises. We argue that a framework that views plants as mixotrophs with an inherent ability to use organic nutrients, via direct uptake or aided by exoenzyme-mediated degradation, will transform nutrient management and crop breeding to complement inorganic and synthetic fertilisers with organic nutrients.
