| Abstract:
Ornamental plant production can cause the contamination of the environment with fertilizer and pesticide residues. This has already led to first regulations by the European Community and, first of all, by the government of West Germany. Closed cultivation systems, which prevent the loss of water and nutrients, should help the greenhouse industry to comply with the restrictions set by the government. Depending on the cultivation system, different types of closed systems must be taken in consideration. Closed cultivation systems result in appreciable consequences concerning plant nutrition and plant pathology. | |
