Hello all, I just got my soil test results back from Logan Labs and I would appreciate whatever help I can get in interpreting the results, and perhaps some ideas for the best ways to make improvements based off these results.
I have attached my results. I am on 1.5 acres on the Mornington Peninsula, Victoria, Australia.
I took 3 samples:
1) the first sample ("West") is top soil at the highest elevation of my block which is on the west side
2) the second sample ("East Top") is top soil from the lowest part of my block which is on the east side.
3) the third sample ("East Sub") is the clay sub soil from the lowest part of my block which is on the east side.
I have just read The Intelligent Gardener so my observations are largely based off what I have learnt there.
My observations:
Sample 1 - A reasonable light (lowish TCEC) and very acidic soil, as I already knew from home testing. Magnesium levels look fine, so mostly looks like I need to add quite a bit of lime to fix pH. Also seems to be like a lot of other imbalances, like very low P, low K, and a lot of Fe.
Sample 2 - TCEC 3 times as high as sample 1 and OM% high as well as I'd expected from looking at the soil. Also very acidic, with magnesium being a bit on the high side, and calcium really lacking. This low part of the block is close to an estuary, about 1km inland from the sea, which get's very wet when we have a lot of rain. I am guessing this is the reason the sodium levels here are so high. Any strategies I can use to make this area productive? Could I make raised or mounded garden beds and hope the sodium will eventually be flushed out, or will it continually wick back up into the soil?
Sample 3 - As mentioned, this is the clay subsoil that is about 1m below in the same area as sample 2. I had been hoping to see a high TCEC in this clay so I could dig some up for use else where, but doesn't appear to be the case.
Another question - My iron levels are apparently very high, is that because iron is very available in low pH soils like mine, and will this be remedied by bringing the pH to a more appropriate level?
Please let me know your thoughts and what actions you would take. Thank you
