HOW IS OKLAHOMA NRCS ASSISTING WITH IRRIGATION AND SAVING WATER? INSTALLING MORE EFFICIENT IRRIGATION SYSTEMS DEVELOPING IRRIGATION WATER MANAGEMENT PLANS PROMOTING IRRIGATION SCHEDULING USING EVAPOTRANSPIRATION (ET) PROMOTING WELL DECOMMISIONING
HOW CAN WE MAKE SYSTEMS MORE EFFICIENT? CONVERTING FROM LESS EFFICIENT FURROW OR SIDE ROLL IRRIGATION SYSTEMS TO MORE EFFICIENT CENTER PIVOTS OR LINEAR SYSTEMS CONVERTING LESS EFFICIENT SPRINKLER SYSTEMS TO GREATER EFFICIENCIES OR REPLACING WITH SUBSURFACE DRIP SYSTEMS
GENERALLY SPEAKING, WHAT TYPES OF INEFFICIENT SYSTEMS ARE WE REPLACING? Furrow Systems Hand Move Systems Side Roll Systems Conventional Impact Systems Conventional Spray Systems
FURROW IRRIGATION
FURROW IRRIGATION USING SIPHON TUBES
FURROW IRRIGATION USING GATED PIPE AND SURGE VALVE
Furrow Irrigation Using Collapsible Gated Pipe
Hand Move Sprinkler System
CONVENTIONAL SIDE ROLL IMPACT SPRINKLER Side Roll Sprinkler System
CONVENTIONAL IMPACT
CONVENTIONAL SPRAY
WHAT TYPES OF SYSTEMS ARE WE PROMOTING TO REPLACE THE OLDER LESS EFFICIENT SYSTEMS? LEPA - Low Energy Precision Application LESA - Low-Elevation Spray Application LPIC - Low Pressure In-Canopy MESA - Mid-Elevation Spray Application Subsurface Drip Irrigation Systems
