The Westsik’s long-term crop rotation experiment was set up in 1929 at the Nyíregyháza Experimental Station (NE Hungary) on a slightly acidic Arenosol. Besides fallow (CR), effects of different organic amendments (lupine as green manure, lupine main crop, straw and farmyard manure (FYM) were studied with or without N NPK-fertilizers. consisted rye, potato, lupine, oat common vetch. soil potato ...

Zeolites have been increasingly used in various application areas such as industry, agriculture, environmental protection, and even medicine. Although, there are no certain figures on the total amount of these minerals the world, some countries e.g. Cuba, USA, Russia, Japan, Italy, South Africa, Hungary and Bulgaria, have important reserves and production potentials. According to reports of 200...
