  1. Hi Kathy.

    Could you ask the researchers if the increased conductivity of the manure-treated soil might be due to higher levels of organic carbon and water-stable aggregates? It would seem like the soils with these two characteristics would likely also hold more water molecules, which make me think they would have higher conductivity. (as opposed to assigning blame to higher salt content).

  2. I don’t have full access to the article but wanted to do some extra reading. I don’t doubt the results, but I am curious – how did the nutrient (NPK at least) content of the manure compare to the fertilizer? Again, I don’t doubt the benefits to soil in terms of WSA, OM, and pH…but comparing soil N is not particularly meaningful if the nutrient levels applied was significantly different between forms. Kathy, got a link to the PDF itself, or can you write a bit about that? Thanks!

  3. Kathy, Thanks for sharing this long term study, ’03 to ’15.
    At our local farm coop last Sept, the manager was pushing me hard to apply his inorganic fertilizers to my pastures vs. the chicken litter we typically use.
