Why is soil better than hydroponics?

The difference is that the nature of soil based minerals is slow release whereas hydroponic minerals are fast release with fast up-take, thus optimal results & faster growth. In soil, a plants roots must go in search for nutrient. This is why typically a soil based plant has a much larger root system than hydroponic.
