"In seconds?" You either have an instance of Random Things where the fertilized dirt is configured with a MASSIVE growth buff, or you are engaging in a truly ludicrous level of hyperbole. With just the fertilized dirt alone (and NOT intentionally configured to be obscenely overpowered), you'd still be looking at a few days, if you're just using an initial seed crop with the standard chance of getting a second seed, to get your "infinite ores;" another ludicrous hyperbole because those ores take time (I'll cop to it being slightly less than on regular farm land) to grow, in addition to the time and resources going into their processing. Calling their interaction overpowered, or even more hilariously an "exploit," would be like calling the interaction between Magic Crops and a single Lilypad of Fertility to be overpowered because it gives you a tiny gain in growth speed.
Now, if you combine the fertilized dirt with fertility lilies, you may have a small case assuming you use a metric tonne of of the latter. Combining those with lamps of growth and/or a RotaryCraft fertilizer? Oh yeah, THEN you're talking about something that might be considered a little cheaty, depending on to whom you're speaking. However, the (again, by default) tiny growth increase from fertilized dirt alone isn't anywhere near the realm of an exploit, unless you're somebody like Greg, who would consider a machine that gives you one extra tiny dust out of your ores than what his machine provides an exploit. Once more, you would have to intentionally configure Random Things to be overpowered for it to actually be overpowered.
This isn't an "exploit fix," this is a bug, even if Lumien might (again, don't know, haven't heard his opinion either way on this matter) consider it to be the former. Its just like MFR not natively working with force trees from DartCraft. That was a bug that Skyboy simply refused to fix, so someone else decided to fix it for him with DartPatch, but that whole thing is another gripe for another day.
In the vein of Random Things, fertilized dirt (as of 1.7.10) does need to be tilled to work now. However, once it is tilled, it stays tilled until something actually breaks the block itself. No amount of jumping or landing on it, no matter from what height you do it (I've tested it all the way from build height to sea level) will untill it. A slight annoyance, but one that's easily rectified with a hoe. Also, vanilla crops work on it just fine, it just seems to be mod crops that don't like it. For example, RotaryCraft canola will plant on the dirt, but refuse to grow, even if you apply the beauty of a reinforced watering can straight to its proverbial face. Wheat, potatoes, and carrots, however, work exactly as advertised, so I'm chalking this up to a mod crop bug of some sort.
