No..... Fert needs are pretty low. I’m guessing a lot of what is happening is due to my really low CEC soils. I kind of wonder if the soil test folks aren’t recommending too much lime to be applied at one time on this kind of soil. Ideally on this sand, I bet you would probably be better to apply something like 500-1000 lbs every 6 months for several rotations rather than dumping one big load out in one dose. I don’t know though. I’m not sure what it happening to the rest of that lime. I have good infiltration on this field and don’t have much runoff so the lime doesn’t have much choice but to leach down. If it’s leaching into that subsoil and making it a more hospitable growing environment, then that wouldn’t be a bad thing. Like I was saying in the other post…it may be 3,000 lbs of lime but the cubic feet of dirt we are talking about conditioning is pretty massive if the lime is leaching into the subsoil.

When I first made this a foodplot and broke it up for the first time, I had a balanced pH of 6.8 with 1200 lbs/ac of Ca. It used to be a horse pasture so I assume it got horse manure applied on the regular. It had been fallow for several years when I bought the place. When I brought it back to 900 lbs with that first application of lime, I wasn’t far off from being back where I started. The difference now though is I figure I’ve probably built more holding capacity than I had originally had with all the OM I’ve added….. so it will likely take me having closer to 1500 lbs of Ca to balance. Maybe this application will get us there.
