Ricardo Bemfica Steffen, Gerusa Pauli Kist Steffen, Joseila Maldaner

Abstract
The advances in productivity and product quality observed in world agriculture lead to the use of new technologies capable of meeting current demands. The use of low frequency electromagnetic fields has shown significant results. In this context, the objective of this study was determine the effects of Penergetic technology on the direct stimulation of beneficial soil microorganisms under in vitro conditions. Mycelial growth and conidial formation of Trichoderma asperelloides, mycelial growth of ectomycorrhizal fungi Pisolithus microcarpus and Suillus sp. and the multiplication of bacterial cells of Bradyrhizobium japonicum species in culture medium with and without the addition of Penergetic. Significant increases in fungal and bacterial growth were observed when using the commercial biostimulator in culture medium. The use of sustainable technological tools represents a viable path because it consists of a solid and efficient management alternative capable of increasing the stimulus to biological development in the soil and, consequently, to agricultural productivity in an environmentally and sustainable safety.
