Center Pivot Irrigation Systems

• Became the System of Choice on the Texas High Plains. • Why? - You Tell Us • How? - You Tell Us Mid-Elevation Spray Application (MESA) LOW ELEVATION SPRAY APPLICATION (LESA), 5 DEGREE UP (BLUE) PAD, WHAT WE USED TO GET WHERE WE ARE Low Elevation Spray Application (LESA) LEPA BUBBLE (QUAD APPLICATOR) GOT ADEQUATE WATER TO PEANUT PLANTS IN SANDY SOIL. With 3.5 TO 4.5 DAY REVOLUTIONS EARLY IN THE SEASON, SOIL CAPILARY ACTION MOVED WATER LATERALLY TO DEVELOP PLANT ROOT SYSTEMS WHERE WATER WAS APPLIED. AT BLOOM & POD SET, SYSTEM SPEED WAS REDUCED TO 6.5 or 7.5 DAYS TO GET WATER INTO THE PRIMARY PLANT ROOT STRUCTURE WITH LESS. IT WORKED. 4000 LBS & MORE PER ACRE. Irrigation Is About Hourly, Daily & Seasonal Soil, Water & Plant Relationships

• Know/Understand The Soil Type Under Your Center Pivot • Know How Much Available Plant Water Your Soil Can Store To Produce A Crop • Accept Irrigation Application Efficiency is Highest When You Do Not See The Water • You can Identify How Much Water You Apply • Soil Moisture Sensors/ Probes Can Tell You Where Water Applied Went • Soil Moisture Sensors Can Tell You Where Crop Roots Are • Soil Moisture Sensors Can Tell You Where and How Much Available Water is in the Crop Root Zone • Manage Your Crop Root Zone Using Your Irrigation Capacity What Creates Water Application Losses? • Wind Speed • Low Relative Humidity • Temperature

• Evaporation - Mist LEPA LDN Shroud Bubbler@ 30” - Droplet Size • Runoff • Seepage Below Root Zone Irrigation Systems Must Get 90 % or More Of Water To The Crop

LEPA Spray is Tough In Wind • LEPA has been • Do We Lose proven to Get Too Much 95% In Corn Water In Application • Bubble or • Can You Do • Drag Sock Better? We Can Manage Evaporation Losses • Prevent Mist by Low Pressure Design • Applicator Selection • Water Application Control/Placement • Apply Water only on Soil Surface to move into Root Zone. • Use Soil Probes/Devices to Monitor Water Movement Infiltration & Available Soil Water to 48”. We Learned Roots Go To Where Water Is Placed
