Crop trays are used for above-ground cultivation, mainly in urban agriculture projects.
Trays can be designed to respond to various problems: optimize water retention, the bottom being filled with clay balls for instance, or respect weight constraints per m2, in the case of roof gardens for instance, imposing very strict standards to meet. Farming in trays also makes it possible to control the potentially invasive cultures, to manage their proliferation. The composition of the soil can also be adapted tray by tray to the needs of the plants.
