- The advantages of hydroponics over soil based farming
1.Saves space
- The hydroponics' vegetable are being grown on trays stacked on top of one another so hydroponics farming does not need a large plot of land.
- While soil based farmimg needs alot of land.
2. Saves water
- The water is in a tray below the tray that the vegetables are on and the roots of the plants are just left dangling in the space between and the tip of the root touches the surface of the water to suck the water up.
- Whereas, for soil based farming, the water can seep into the ground thus the plant may not absorb 100% of the water. Hydroponics farming therefore requires a smaller amount of water then soil based farming.
3. Does not cause pollution to the environment
- In hydroponics farming, no fertilisers are being used as the nutrients for the plants are in the liquid form.
- Whereas for soil based farming, the fertilisers that are used will emmit a type of green house gas called nitrous oxide which contributes to global warming.
- And no pesticides are used in hydroponnics as the plants are either in greenhouses or are being protected by netting.
- But for soil based farming, pesticides are being used to prevent insects from destroying them which also contributes to pollution of the environment.
Disadvantages
Although hydroponics farming requires a huge amount fo capital investment for the computers, and the building of greenhouses, it is worth it does not does harmul things to the environment. Furthermore, the quality of crops from hydroponics is high and has more vitamins,
