Urban Farm DB summary
In spring and summer 2018, in a rooftop greenhouse near Barcelona, coir, vegetable compost from urban organic waste, perlite, and a mixture of compost and perlite substrates were evaluated over three consecutive crop cycles of lettuce. This study aimed to assess the use of substrates made from local materials as an alternative for urban agriculture during periods of water supply cuts. Results showed that compost and the mixture yielded similarly to perlite, and organic substrates increased crop resilience to water restriction.
