Goals:
acquiring of soil science, crop growing, business management, and ecological fundamentals of site-specific measures in crop produc-tion
developing of algorithms, modules, and software taking into ac-
count site-specific and environmental quality-goals in: soil cultivation seeding fertilizing (N, P, K, organic fertilizer)

precision agriculture are applied and verified
2.official recommendation (LUFA) (averaging soil and uptake values)
N - fertilisation: felxible (mit Sensor)
3. official recommendation (LUFA) (soil nutrient content values and yield) 4. fertilisation according previous uptake (replacing just the crops uptake)
general fertilisation (P, K, lime) driving tracs
N - fertlisation combination
N - fertilisation: constant
1. none
