Abstract
Fungal flora of four crops, cultivated with and without nitrogen fertilization was investigated. Samples of legume and grass leys were taken from the standing crops on harvesting as well as from the dried hay. Samples from oats and barley were taken from the standing crops at harvest and from the same plots after conventional harvest and drying. Storage was carried out in a barn for about six months. Field fungi dominated on greenstuff and grain, irrespective of the method of harvesting the grain, while small amounts of storage fungi were seen on hay. This field flora remained in general unchanged after storage. Only in the material with a water content of about 20%, which was harvested aseptically from standing crop and stored without access to air, the field flora had disappeared and besides a surface population of fungi, an internal growth of Aspergillus, Penicillium, Paecilomyces and yeast species in the kernels had occurred. The difference between material from nitrogen fertilized and non-nitrogen fertilized soil was, also after advanced statistical analysis, insignificant in all treatments, and nothing in the experiment indicates that nitrogen fertilization impairs resistance to fungal attack during storage, if the material has been dried and stored carefully.
