Abstract
The present invention relates to an apparatus controlled by computers, for applicating fertilizers through automatic water-spray in a golf link, farm, garden, indoor garden and flower-vegetable garden on a terrace and roof of a building. The apparatus comprises a storage pump for pumping up water from a water source; filter devices for filtering the thus pumped-up water; injector devices for mixing fertilizers, agricultrual chemicals, bacteria and the like with the water; pressure regulating valves for uniformalizing the pressure of the water mixed with fertilizers and the like in a plurality of branched paths; water-spray devices for spraying the water thus uniformalized in pressure; and a control device for organically controlling the above devices.
