Test your soul in different areas for PH. Mix up your sulfuric acid and water in different ratios then apply it to the different soil areas tested. Give it a few days and test the soil ph again in each area that you previously tested, which one worked best?

I've done sensor measurements with my hydroponics setups and haven't done them in soil, but I can give some insights especially regarding pH sensing. To quickly answer your question: up to you how much you want to spend on how many sensors. Moisture/Temp/EC can be useful at all levels and the tiering detailed in the photos make sense. There are more sensors ...

It's amazing how many people on these forums try to take an upper hand and worry about pointless garbage coming from a total lack of experience. I was a molecular biologist for 20 years and I have had more years of botany labs than I care to remember. dilute Sulfuric acid is the quickest and safest way to lower pH - elemental sulfur is great if you want to ...

It doesn't look like a fungus or mushroom to me. I think you have slime mold, something in the Arcyria genus. Mycelium doesn't usually grow above the top inch of soil--but slime mold colonies will come up if conditions are right. They're really cool and most species are benign to plants. They're not a mold, actually related to amoebas! They live as single-...

Very few plants can tolerate much salt in the soil. There are some exceptions in costal areas like mangrove. But it requires a lot of salt ; the amount you put on food will have no effect. If a large amount of salt is used, plants will not grow, or grow poorly until rain rinses the salt away, which may take years ; depending on the relative amounts of salt ...

I would plant it in the ground and train it to grow up and over ...

You can't usually just "dump topsoil" on top of what is already there, because if you add enough topsoil to make any difference (i.e. 100 to 200mm) you will raise the ground level enough to cause problems. For example the new soil will get washed over existing paths and driveways, or cover the damp course layer in the house foundations. Note, I am ...

In my opinion (and you can probably get as many opinions about this as there are posters on this site), what you do depends upon what the builders did. The big question is: Did the builders spread spoil from the apartment across the top of the topsoil that was already on the site? If the builder did remove most of the spoil, gravel, and debris, then you can ...
