Abstract

ROTOR is an agronomic planning tool used by farmers and consultants to generate and evaluate crop rotations, which are crucial to organic farming systems in terms of their projected yields, humus-, nitrogen- (N), phosphorus- (P), and potassium-(K) balances, considering weed infestation risks and phytosanitary restrictions. ROTOR has been developed since 1997 at the Leibniz-Centre for Agricultural Landscape Research (ZALF). A rule-based static approach is used to determine crop sequences and to assess their yields.
