Non phone link. Looks pretty decent for $60. I saw these for the super cheap route.

watering Every day is important. dirt is a sponge. Ever notice how a really dry sponge lets water roll right off it? dry dirt leaks water too fast, the dirt has to be semi moist already to really soak up your waterings.
That.s why I get watering systems. this is my favorite:

it looks ridiculous, but works THE BEST.
Corrosion is always going to be a problem when you have probes in soil and water. And typically, it builds up more on one of them. Some project I saw once, used a H-bridge or similar to alternate the direction of the current between measurements. However, in the end the problem remains.
Personally, I've given up on moisture sensors because they're way too inaccurate. They will vary based on the type of soil, the type of plant (and its roots), and like you've seen, corrosion. Measurements are all over the place, whether you just watered or if it's been dry for a week. (And don't get me started on the relays which brake, water pumps which jam, Arudino which crashes. Been there, done all that).
In the end, nothing beats looking after the plans. When away, use some self-watering probes like these to delay the dry-out. Or ask a neighbor or friend to come by.
Sorry to rain on your project..
