Features of Usage of Electromagnetic Field of Extremely Low Frequency for the Storage of Agricultural Products

Abstract

The way of increase of storage period of agricultural raw materials under the influence of low frequency electromagnetic field (EMF LF) has been considered in the article. Existing developments of the EMF LF usage on the base of patents have been examined. The results of EMF LF processing of wood, wine, seeds, vegetative, fish and meat products have been presented. The magnetic field as an active factor in agriculture has more than 50-year history. Important applied investigations were made in Russia, the results of which were the creation of technological lines of magnetic systems for pre-processing vegetative plantings seeds. Conditions under which the application of the magnetic field shows stable results stimulation-increase of the yield by 12%-30%, depending on the culture, the initial quality of the seeds and growing conditions of plants-were found out. The main application results with the help of gradient magnetic field (GMF) application have been obtained. Low energy consumption of GMF-processing of seeds in combination with a low intension of magnetic field (1-12 mT), absence of noise magnetic field outside the zone of seeds processing (a level of tension equals 0.01 mT at a distance of 0.5 m from the processing zone) makes these plants absolutely safe for service personnel. Non-high price of GMF-plant complements the advantages of this equipment. Almost all the scientific works devoted to the impact of electromagnetic field of EMF LF or of GMF, were intended to stimulate the vitality of plants.
