In this article we will discuss about the advantages and disadvantages of sub-surface drip irrigation. Sub-surface drip irrigation (SDI) is a low pressure, low volume irrigation system that uses buried tubes to apply water. Applied water moves out of the tubes by soil matrix suction. Wetting occurs around the tube and water moves out in […]
