  1. pre agro - Management system for site specific crop production- to increase the profitability of agriculture and to enhance the benefits for the environment -

  2. site characterization soil, relief, water, climatic conditions deriving yield potential general planning of crop management crop species, variety, quality-goals specific planning of verification of measures crop stand management sowing harvest herbicides actual situation of the crop stand N 1 N 3 N plant growth regulators 2 fungicides Information flow for site specific management of winter wheat according pre agro

  3. Intentions of the German joint R+D-project pre agro for site specific crop management
