Different chemical additives are used for rising productivity of plants and animals. Their application causes the contamination of raw materials for food production with toxins that is dangerous for consumers’ health. On-farm safety for fresh produce needs developing and implementing new methods for quality assurance. The influence of physical factors as microwave and laser radiation, magnetic field and ultrasound treatment is an alternative of soil additives and fertilizers. The substitution of chemical amelioration by physical one can reduce the toxins in raw materials and thus – raise the food safety. The use of some physical factors (laser irradiation; ultrasound influence; irradiation with microwave electromagnetic rays; magnetic field influence, gamma irradiation) for stimulation of seed vitality in Bulgarian agriculture has been discussed. |
