Scope of the Symposium:
- The 25th CIEC symposium was thematically dedicated to the significance of sulfur in high-input cropping systems. The reason is simply that one of the global competence centers of sulfur research is located in Groningen. Beyond this sulfur deficiency causes worldwide avoidable yield losses, diminishes the nutritional quality and reduces nitrogen utilization efficiency of crops. The Netherlands are characterized by extremely high levels of agricultural production and big animal enterprises, which induce substantial environmental problems such as release of trace gases contributing to climate change, contamination of ground- and drinking water with nitrate and non-sustainable use of the finite resource phosphorus. Besides the implementation of GAP (Good Agricultural Practice) codes and the strict compliance with rules of balanced fertilization, novel technologies such as the acidification of slurries with sulfuric acid for reducing the release of nitrogenous gases are required urgently in order to tackle these problems. Recycled fertilizer products as for instance digestates from biogas plants offer a way to utilize manures and slurries. However, aspects of phosphorus speciation, risk of contamination with organic xenobiotics and heavy metals, and infectivity by pathogens need to be evaluated in the course of fertilizer value and soil protection.
The Symposium addressed various topics of global interest and the presentation of innovative data in fertilizer research is appreciated explicitly. The major subjects are: Sulfur metabolism in crops, mechanisms & applications to food security • Increase of fertilizer efficiency by optimized nutrient ratios & nitrification inhibitors • Strategies of efficient use of nutrients from manure, slurries & secondary raw materials • Efficient use of phosphorus • Balanced fertilization & nutrient balances • Secondary nutrients: silicon & micro-nutrients!
- The symposium brought together 48 scientists from 19 different countries.
Submission of full papers for publication: any time after the symposium!
- Authors of contributions accepted for presentation at the symposium are invited to accomplish a full paper. The manuscripts can be submitted to the Journal for Cultivated Plants (Eugen Ulmer KG, Stuttgart) after the Symposium. All manuscripts are subjected to peer reviewing.
