Soil based agriculture is more practical than hydroponics because: soil does not leak or evaporate; the fish used to provide nutrients, utilized in some cases, are more fragile than soil; chemical hydroponic nutrients require supply chains, whereas it is possible to transform barren land into soil anywhere; hydroponics requires an uninterruptible source of electricity; and setup and operational costs for hydroponic systems are significantly higher. Soil, arguably, provides more nutrients and micro-nutrients than hydroponic fluids.
