Title:
IRRIGATION AND FERTIGATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/101542
Kind Code:
A1
Abstract:
The present invention relates to an irrigation and fertigation system. A turbidity sensor is installed between a discharge pipe and a first branched pipe, and turbidity of ground water flowing in from a well by means of a feed pump is measured at the discharge pipe, and when the value of the measured turbidity exceeds a reference turbidity value for ground water, a conversion valve (30) is activated downward to drain the ground water, and when not exceeded, a conversion valve (26) is activated upward to allow the ground water to flow through to a distribution pipe, thereby preventing small spray holes of a drip pipe from becoming blocked. A transparent pipe is provided to one side of the discharge pipe (22) to allow turbidity of the ground water to be visually determined, and when the water discharged from the feed pump is confirmed via the transparent pipe to be mixed sandy water in which sand is mixed in, the conversion valve (30) is activated downward to drain the ground water, and when no grains of sand are seen via the transparent pipe in the ground water discharged from the feed pump, the conversion valve (26) is activated upward to allow the ground water to flow through to the distribution pipe, thereby preventing small spray holes of the drip pipe from becoming blocked. A liquid fertilizer feed pump is installed to one side of a liquid fertilizer inflow pipe to facilitate smooth supply of liquid fertilizer thereinto, regardless of whether a liquid fertilizer supply tank is at the same level as or lower than the irrigation and fertigation system.
