Aeroponics is considered one of the best methods to grow plants in a soil-free environment and the need for this method has been growing due to a clear need for a more convenient way to grow plants. Plant roots are hung in the air in a grow chamber in a closed-loop system. The roots are sprayed with nutrient-rich water or fine, high-pressure mist containing nutrient-rich solutions at certain intervals.

Advantages:

• Maximum nutrient absorption for plant roots due to no growing medium
• With this type of modular system, you can maximize the use of limited space.
• Considerably fewer nutrients and water used on average compared to other systems because of higher nutrient absorption rate.

Multilayer farming is a modern integrated farming system in which 4 to 5 different crops are cultivated in the same crop-field in a specific time. In this farming technique, farmers come up with multilayer seed sowing in which different vegetable and fruit crops are being sown in deep, middle, top, topmost layers of soil, according to their respective root zone, simultaneously in a single crop field.

Advantages:

• In Multilayer farming, the cost of cultivation is 4 times lower, whereas the advantage is eight times higher than another farming system.
• In the Multilayer farming process, the total amount of fertilizer and water for cultivating four crops is as much as the cultivation of one crop.
• Prevents water evaporation from the soil as an effect, 70% of water is saved.
