Abstract

The present invention provides an automatic nutrient supplying system. This system is provided with an inflowing air intercepting device (40) for almost completely preventing atmospheric air from undesirably flowing into a fertilizer pipe (31b) when a liquid-fertilizer tank (30) is empty during a nutrient supplying operation of the system. This system is also provided with a valve means (50) for controlling the flow of liquid fertilizer within the fertilizer pipe (31b) and removing negative pressure from the pipe (31b). Both the inflowing air intercepting device (40) and the valve means (50) are mounted to the fertilizer pipe extending from the tank (30) to a feed pipe (15), with an air pipe (31d) connected to the valve means (50). The valve means (50) may comprise one or more two-way valves (91 and 92). The air pipe (31d) may be opened to the atmosphere at a position higher than the fertilizer tank (30) and may be provided with a manual valve (99). The system effectively prevents atmospheric air from undesirably flowing into the fertilizer pipe (31b), and effectively supplies water to plants even when atmospheric air flows into the pipe (31b). The system normally performs its desired operation when new liquid fertilizer is being refilled into the empty tank (30). The system is thus free from malfunctioning during a nutrient supplying operation and is free from damage to a pump (60).
