Abstract

Throughout history, humans have depended largely on agricultural products for basic survival. As technology continues to develop, new ways of more efficiently cultivating these crops have emerged. People have tried various different techniques: using better soil, changing irrigation schedules and methods, and seed improvements to list a few, in hopes of improving yield. This study explores the effectiveness of subsurface irrigation compared to traditional surface drip irrigation in water conservation whilst maintaining healthy crop growth. Using baby heirloom lettuce as the test plant, both irrigation systems were designed and monitored under controlled indoor conditions, with soil moisture sensors changing irrigation schedule based on readings. By doing so, the study aims at determining how subsurface irrigation and responsive sensor control can improve irrigation efficiency. This offers insights into sustainable, data-driven farming practices, allowing plant growers around the world to have a more optimized and efficient system. The results showed that subsurface irrigation is better for plant growth compared to above surface drip, but uses slightly more water.
