Overview

Simulation reveals micro-sprinkler systems lower groundwater contamination risk in strawberry crops, suggesting better irrigation methods.

Key Points

  • This research aims to evaluate the impact of different micro-sprinkler systems on groundwater contamination within Florida's strawberry production.
  • Used HYDRUS-1D simulation with parameter inversion to analyze irrigation systems.
  • Conducted Sobol global sensitivity analysis to quantify water dynamics in various sprinkler systems.
  • Compared infiltration rates of four micro-sprinkler systems and conventional impact sprinklers.
  • Residual water content was the dominant factor affecting model predictions (sensitivity index ST = 0.88).
  • Cumulative furrow infiltration varied significantly, with micro-sprinklers reducing percolation by 89% compared to conventional systems.
  • Implementation of the Mini Revolver system could prevent substantial deep percolation, enhancing water-use efficiency.
