Today we’re talking all about nitrogen-fixing biologicals. What's the best definition of a biological or biostimulant? Are they fertilizers, pesticides - or neither? In what ways do they interact with nitrogen in the field? Where and how are biological products tested? Which environmental factors might impact biologicals? How should they be properly transported and stored? How can farmers assess whether biostimulants might be right for their operation? All this and more on today's episode.
