The efficiency of natural foliar fertilizers

In the light of the agricultural development, microbiological products have increasing significance, since it is possible to improve soil fertility and tolerance of cultivated crops, and the use of chemical fertilizer can be reduced. The efficiency of natural foliar fertilizers was examined in a three-year long analysis (2006-2008) in the southern production area of Hajduszoboszlo on meadow chernozem soil. During the examinations, the primary question was whether the foliar fertilizers Natur Vita (Chlorella vulgaris and Spirulina platensis), Natur Plasma (Chlorella spp.), and Amalgerol Premium (alginate, mannitol, laminarin etc.) provide further yield increase on top of basic fertilisation in maize population and stubble field treatments. The efficiency of products was tested in hybrid seed production, and the examinations were extended to potato production, too. During the statistical evaluation of the research results, it was established that the use of the tested foliar fertilizers improve the vital conditions of the hybrid seed production. Depending on the applied treatment, foliar fertilizers provide further yield increase on top of basic fertilization, and their combined use does not result in significantly higher yield than in the case of applying products individually.
