An Intelligent Water-Saving Irrigation System

Abstract

With the rapid growth of the world’s population, the shortage of freshwater resources becomes increasingly serious. Farmland irrigation would not survive without fresh water which comes from river nearby. The low irrigation efficiency of the existing irrigation system needs to be tackled for efficient and effective usage of freshwater with low-cost. It is recognised that the water-saving irrigation technologies, such as the drip irrigation, sprinkler irrigation, micro-irrigation, furrow irrigation in horizontal direction, plastic film mulching, ditch irrigation technology, etc. should be strongly promoted in order to develop water-saving agriculture. However all these measures require cutting-edge technologies and heavy investment, which poses a big problem particularly for the developing countries. On the other hand, if water and nutrients can be applied directly to the crop at root level, the positive effects on yield and water savings can be achieved, thereby increasing the irrigation performance. The water-yield relationship has been investigated using different methods of limited water applications and programs. Therefore, designing and fabricating technological irrigation system of low cost with maximising yield that can reasonably use water for agriculture is an urgent issue to today’s world. The intelligent irrigation system provides a potential solution to solve the water shortage problems. In this study, an intelligent water-saving irrigation system is designed using Solidworks and some parts of the system are fabricated using a home-made fused deposition modelling (FDM) 3D Printer. The intelligent irrigation for different plants is successfully achieved and the irrigation efficiency is significantly improved. The employment of the home-made 3D printer not only substantially reduces the manufacture costs, but also makes it possible to fabricate any “ad hoc” irrigation system.
