Summary
Fertile soils are one of the most valuable non-renewable resources on earth and agricultural production must preserve their natural status without interfering with other ecosystems. At the same time, agricultural production must feed the world population of tomorrow with high quality food. Site-specific fertilisation promises to meet both demands, but after more than a decade since precision agriculture technologies have been available, their implementation on farms is low, because they do not satisfy economic returns. Other problems are the efficient capturing of geo-coded soil and crop information and the development of tailor-made algorithms for the variable input of different nutrient sources such as mineral, organic and secondary raw material fertilisers. It was the objective of this contribution to give an overview of agronomic, ecological and economic aspects of site-specific fertilisation.

 
Relevance
One promising way to reduce nutrient inputs into the Baltic Sea is the development of tailor-made algorithms which allow a variable site-specific application of different inorganic and organic nutrient sources. Hence, one aim of the project BALTIC Manure will be the development of such algorithms for manure to present one feasible method to reduce the nutrient run-off from agricultural land.
