Thanks Stephen- I am not sure if there is a link missing there.
Perhaps the micronized pelleted lime is the right choice. John mentioned before that calcium carbonate is really what I should be looking for.
I could really use some clarification on calcium type and application in general, I think. In my mind, pelletized lime or similar would just sit on the surface of the soil until water dissolves it or? I would also expect to see irregularities in a soil test if there are larger particles of CaCo2 captured in the sample. In this context, it won’t be tilled in. To my way of thinking, what I really want is a homogenous blend of calcium across and through the soil profile as a whole, so in that way of thinking I feel like a liquid application really seems like the ideal mode of applying the material. Are there pieces of this that I am missing?
Another thought I have here is regarding the keyline vertical tillage I am doing. We have this sandy, seemingly structureless soil here- I am considering rigging up a tank to drip calcium into the rips, because I have some concerns about the sand just immediately collapsing back into the rips. Perhaps adding some calcium into those rip lines will prevent that from happening to some degree- maybe the pelletized lime is the right answer for that operation. I am not sure how that fits in to my broader overall calcium application, as I do want a homogenous calcium blending as I said earlier.
Another aspect I am unclear on about the GSR calcium is how the application rates tie in with desired values- there is something I am not understanding there. If my ppm calcium on a field is at 350 ppm, that would mean that I need to apply 1300 lbs Ca/acre to reach 1000 ppm. According to Soilworks, application rates of their product are in the 1-2 lb arena, rather than being measured in tons. Is that because it is down into the 1 or 2 micron size, and therefore extremely available? How does that fit in with the physical soil structuring and flocculation?
Thanks for the conversation- there are quite a few things I’m trying to figure out right now, and I’m leaning heavily on those Kind Harvest members who are much smarter than I am!
