This podcast is a follow up to our earlier conversations (make this a link) with Bill McKibben. Bill is the author of The Art of Balancing Soils, and when it comes to this particular art, he is undeniably a true master. He talked about the importance of soil chemistry and how it can affect soil physics. This week we invited the EarthWorks Chemist, Lawrence Mayhew, to the conversation to discuss the third leg of the three-legged stool: the one that focuses on soil biology. Lawrence, also a master of his craft, helped us better understand how sodium works in the plant and ways we can buffer excess sodium using soil biology. He explained his thought process when he helped us formulate our newest liquid product, and rising star, KVantage. “Sodium can work like high blood pressure in the plant” according to Lawrence, and excesses will lead to sodium-induced wilt stress. Many sources of irrigation waters in the turf industry are very high in sodium, and the constant flush through the soil profile causes plant and soil issues. Lawrence talked us through ways we can offset these problems with biological buffering, backed up as always by a deep well of research. He is always an EarthWorks Podcast favorite, and this conversation will not disappoint.
