The NDICEA model as a learning tool: experiences in 2005G.J.H.M.van der BurgtauthorG.J.M.OomenauthorW.A.H.RossingauthorIn organic agriculture, major part of the plant available nitrogen originates from mineralisation of organic matter. Self-reliance with respect to nitrogen implies limited nitrogen amounts and thus a need for efficient nitrogen management. The NDICEA model is developed to enable assessment of organic fertilization strategies, based on easily obtainable agronomic information. Examples are given on how this model is used in extension work in Holland in 2005.Farm nutrient management2006Conference paper, poster, etc.
