An agripreneur has used waste plastic bottles to set up an aerial vegetable farm. Anthony Mutugi has grown 294 spinaches and kales on a 4m by 5m by 3m space.
The 294 crops may require about 0.02 acres on a flat ground.
The Kiambu’s Juja area farmer has suspended six crops in the one-and-half-litre bottles with a wire string in a shed net wooden structure that creates greenhouse effects for quick growth.
Each of the bottles is lying horizontally with its bellies ‘scoped’ slightly to accommodate about three quarters of a kilo soil and the kale or spinach.Each of the crops is one and half feet away from the other and the space of one row to the other is about one and half feet.
The crops depend on irrigation. The excess water can drain via the uncapped opening of the bottle. Wedding is done by hand in this aerial farm. Soil nutrients are not leeched since the bottle is non-porous.
It is a perfect example for urban farmers, who do not have permanent residences.
They can move with their crops any time by unhooking the strings and dissembling the wooden farm. source
