“…The results generally indicated that the total colony counts and viability ratios of the Bacteria and fungi strains for the EMR exposed samples decreased with increase in exposure periods from zero (0) to ninety (90) days compared to the EMR unexposed samples (Table 1 and Table 2). Though, bacterial species have been reported to differ in their susceptibility to EMR inactivation [22], the results however, were consistent with the findings of [23][24][25], that an increase in magnetic strength caused mortality in E. coli with the organism losing its ability to form colonies and consequently grew at a slower rate than the control. This observation have be attributed to non-thermal (athermal) effect, which has been suggested to have an important role in the suppression of microorganisms in suspension [26], though; the mechanism of action has not been fully reported.…”

Effect of electromagnetic radiations (EMR) from mobile phones on some soil bacterial (Bacillus, Micrococcus, Staphylococcus, Corynebacterium and Enterococcus) and fungi (Saccharomyces, Penicillium and Geotrichum) strains were studied. At the study periods of 0, 30, 60, and 90 days, the total colony counts (CFU/g) and viability ratios of Bacteria and fungi strains were determined on both the EMR unexposed and exposed soil samples. At the exposure periods of 30, 60, and 90 days, the mean total colony counts of all the organisms in the EMR exposed samples were statistically (p<0.05) lower than those of the EMR unexposed samples. The percentage changes in total colony counts of the EMR unexposed and exposed soil samples between 0 to 90 days for

“…The soil is a lossy dielectric, whose losses are strongly dependent on the water content and can therefore be increased after irrigation. The dissipation in MWs applying generates heat that can be conducted to insects, weeds, or fungi, for example, Fusarium Oxysporym and Sclerotium rolfsii (Abate, ; Brodie et al, ; Vitale et al, , ), leading to hyperthermic conditions and then to death of noxious species, ensuring an augmented crop yield (Komarova et al, ; Vela et al, ; Vela & Wu, ).…”

The use of electromagnetic fields to solve issues related to agriculture is an interesting, costeffective, and eco-friendly possibility to be explored. One of the most promising applications is the disinfection of soils obtained by microwave-induced heating. This work deals with the nonlinear computational modeling of such microwave heating of soils in metal raised bed cultivations within a greenhouse. By modeling the dielectric properties of soil, in terms of composition, moisture content, and actual temperature, and accounting for the exact thermal and electromagnetic conditions in raised beds inside the greenhouse, several realistic and nonlinear multiphysics simulations were carried out. The disinfection is directed to fungi, such as Sclerotium rolfsii, and weeds, for example, ryegrass and fleabane. The effectiveness of the proposed procedure is quantified and critically discussed exploiting analytical thermal death kinetics of soilborne plant pathogens and compared to the solarization technique.
