Summary:Effects of raw brown coal ("Kohletrübe"), brown coal modified with ammonia water, NH3, ("Ammonkohle") and composted brown coal ("Biomineraldünger") on plant yield and on selected soil fertility characteristics of a colloidpoor and a coal-bearing dump soil are tested in a pot and field experiment. The results confirm already published results. Therefore chemical modified nitrogen enriched brown coal is a humus fertilizer the influence of which sustained the water and nutrient storing capacity as well as the nutrient transformation ability of colloid-poor dump soils. Soil improving and yield increasing effects of coal fertilisation depend on particular conditions.
