Using Water Precisely When Water is Scarce By: Cody Konen

 First introduced in U.S. in 1960 (Dew Hose)  Has become very popular since 1995  Showed significant advantages ◦ Increased Water Use Efficiency ◦ Less water required ◦ Precise placement of water and nutrients to plant roots

 Close to water source and pumped by diesel or electric motor  Filter arrangement chosen by GPM of system  Fertilizer injection, and or acid injection  Final filter to catch fine particles

 Depending on field size decides your water rate, zone size, and how many zones in the field  Inches of water applied per hour = ( ) X (flow rate, in GPM) / (# acres)  Lot more knowledge of where we are applying and how much than previous method of irrigation

 Usually runs at least 10 days on normal year, on a hotter year may never shut it off  During this operation, we can fertilize crops with nutrients besides phosphorus due to our pH of water and contents will not mix  Apply chlorine for prevention of clogging each emitter  Weekly flushing of PVC and tape lines from debris

 Uses less water and less labor while keeping the same or better yields  Very expensive initial cost on a per acre basis  Only way we can no-till our crops used from this water source.
