Project Description

Subsurface drip irrigation (SDI) is becoming of increasing interest to irrigated field crop producers in Alberta. In addition to improving water use efficiency, SDI can be used for nutrient management during the growing season.

  • There is no study on effect of fertigation frequency during growing season on nitrogen used efficiency and nitrate leaching loss. This study aims to investigate the efficacy of SDF for crops grown in Alberta.
  • The results of the proposed study will help producers who operate SDI systems, or those who consider SDI, make evidence based decisions on SDF strategies for their crops.
