Intentions of the German joint R+D-project
pre agro for site specific crop management
Goals:
acquiring of soil science, crop growing, business management, and
ecological fundamentals of site-specific measures in crop production
developing of algorithms, modules, and software taking into account site-specific and environmental quality-goals in:
 soil cultivation
 seeding
 fertilizing (N, P, K, organic fertilizer)
crop protection
Basic research concept of pre agro for developing
management systems in precision agriculture
Management of
Information
software for farms, contractors:
site specific crop management with soil tillage, N, P,
K-fertilization, herbicides, crop growth regulators,
fungicides
Practical farming
application and testing of
concepts,.algorithms, rules and software
