Companion planting is the planting of different crops in proximity (in gardening and agriculture), on the theory that they assist each other in nutrient uptake, pest control, pollination, and other factors necessary to increasing crop productivity. Companion planting is a form of polyculture.
Companion planting is used by farmers and gardeners for many reasons. For farmers using an integrated pest management system, increased yield and/or reduction of pesticides is the goal.For gardeners, the combinations of plants also make for a more varied, attractive vegetable garden, as well as allowing more productive use of space.
The greenhouse in the rooftop UrbanFarm is for me the best discovery related to rooftop agriculture. When we talk in ways of yield and sustainable city agriculture, a greenhouse is the perfect solution.
It is an easily controllable mini ecosystem, protected from wind (on the rooftops this is an important factor for drying the containers and plants) and with its own humidity metabolism. The ‘tropical ecosystem’ it creates is much more ecological in use of water (a lot is in the air)and as a closed circuit it can also be controlled by sensors on the level of (too much) sun or UV, and fertilizers.
