The guide stems from the desire to offer all beekeepers a practical tool, gained through decades of experience in the field, as a beekeeper, in the laboratory, as a passionate pollen producer and trader, and in the classrooms of the many conferences and courses that the author has held throughout Italy over the years. The reader will find therein, illustrated in detail, all the particularities of the "Metalori method," the story of how the idea of designing a new trap came about, and the necessary directions for collecting, preserving and marketing pollen.In the second part of the volume we read original contributions from scientists and doctors who delve into the different aspects of the food use, preservation and even the usefulness of pollen for our organism, the true promise of "nutraceutics," and who make the volume a complete guide unique in its kind in Italy.
