Shut Off the Runoff

Overview

This project’s question was - Is there a simple cost effective way to reduce agricultural runoff? A hole w as cut at base level of a tin foil pan, placing 45 oz inside and compacting the dirt, and shaping the dirt to form an upward slope in relation to the hole. The d irt was then moved to fit the specifications of the trial : a control group, terracing away from the waterway, building a mound at base level of the slope, and contour lines. Two teaspoons of red dye - to represent fertilizer would then be spread evenly across the surface area. 0. 48 L of water would be applied gently to the surface area to represent the watering of fields in increments of 0.06L, 0.12 L, 0.18 L x1 0.12 Lx2, 0.24 L. This would allow the determination of which trial is the most effective for heavy rains, light rains and rain overall. A bowl is placed b eforehand directly underneath the hole with 0.12 Lof water to collect dye. This allows the substance to be diluted to give a better representation of what shade it produces in comparison to the 9 point scale that was used to evaluate. Every 15 minutes the water shade was evaluated and replaced. Once 45 minutes has passed, 0.12 Lof water was added to simulate rain. Building a mound was the most effective, terracing away from the water (hypothesized as the most effective) came in second and parallel lines allowing more runoff than the control.
