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)
