  1. Optimal Usage of WaterTAIA Lubbock Regional Meeting Jay Yates Extension Program Specialist III Risk Management Lubbock, TX

  2. Texas Southern High Plains Irrigation Situation • Declining capacity • Increased efficiency • Increasing energy costs • Varieties with higher potential yields

  3. FARM Assistance Analysis • Looked at the following cotton alternatives: • Fully irrigate 120 acre pivots with 300 gpm each • Irrigate 1/2 pivots, treat the rest as dryland • Irrigate 2/3 pivots, treat the rest as dryland • Drill new wells to irrigate entire pivots on owned land with 600 GPM • Drilling 4 new wells for the 4 pivots on owned land at a cost of $40,000 each • Water ½ pivots on rented ground * None of the alternatives included DCP Program Direct Payments

  10. Observations From 2011 • TTU Lubbock Mesonet Site • 45.75” Cumulative Reference ET from 4/15 – 9/15 • 2.36” Rainfall during the same period • 98 days of 95 degrees or more • 58 days of 100 degrees or more • Official Lubbock record of 48 breaks old record from 1934 of 29 • 3 bale cotton in 2011 took from 21-35 ac/in with 4-5 gpm per acre capacity • Well irrigated pivots and drip had significantly higher net returns

  11. Petersburg, Texas Dryland planted May 4 – Picture taken August 25, 2011

  12. Shallowater, Texas Pre-watered Only Planted May 4 – Picture taken August 25, 2011

  13. North of Petersburg, Texas Yield .9 BPA Sub-Surface Drip, 1.5 GPM per acre – Picture taken August 25, 2011

  14. Petersburg, Texas Yield 1.5 BPA Sub-Surface Drip, 2.5 GPM per acre – Picture taken August 25, 2011

  15. Lubbock, Texas Yield 3.3 BPA Sub-Surface Drip, 4.1 GPM per acre – Picture taken August 25, 2011

  16. Sandhill, Texas Yield 3.5 BPA Sub-Surface Drip, 4.5 GPM per acre – Picture taken August 25, 2011

  17. South of Shallowater, Texas Yield 3.95 BPA Sub-Surface Drip, 6 GPM per acre – Picture taken August 25, 2011

  18. Not Much Better in 2012 • TTU Lubbock Mesonet Site • 41.13” Cumulative Reference ET from 4/15 – 9/15 • 6.24” Rainfall during the same period • 69 days of 95 degrees or more • 25 days of 100 degrees or more • Official Lubbock record prior to 2011 was 29 from 1934 • Official Lubbock record of 24 tied for 5th most with 1924 • 3 bale cotton in 2012 took only slightly less irrigation than 2011 • Well irrigated pivots and drip had significantly higher net returns

  19. Not as Hot and Dryin 2013But still above average • TTU Lubbock/Reese Mesonet Site • 42.09” Cumulative Reference ET from 4/15 – 9/3 • Would expect another 2.5” over next 2 weeks based on forecasts, making 2013 as high of ET as 2011 • 7.82” Rainfall during the same period • Normal rainfall is 11.24” for this period • 33 of top 36 driest periods on record for Lubbock come between 9/15 and 4/15. (That’s why winter wheat is not as successful here) • 48 days of 95 degrees or more • 13 days of 100 degrees or more • Still warmer than average (~10 days/year), but closer to average temperature compared to the past 2 years.

  20. Comparative Profit Analysis 2011 • Interviewed area farmers • Collected data from AgriLife Research & Extension Projects

  21. The Study Group • 31 Cotton Farm Sites • 17 Sub-Surface Drip (all on 80” centers) • 13 Center Pivots • 2 MESA • 1 LESA • 10 LEPA • 1 Furrow • GPM/Acre ranging from 1.5 to 6.0

  22. 2011 Cotton Yields vs. Water Applied Cotton Yield lbs/acre Inches of Water Applied per Acre

  23. 2011 Returns Above Direct Costs at $0.90/lb vs. Water Applied at $9/in Returns Above Direct Costs > 4 gpm/ac Inches of Water Applied per Acre

  24. 2011 Cotton Net Profit at $0.90/lb vs. Water Applied at $9/in Returns Above Direct Costs > 4 gpm/ac Inches of Water Applied per Acre

  25. 2011 Returns Above Direct Costs at $0.52/lb vs. Water Applied at $9/in Returns Above Direct Costs Inches of Water Applied per Acre

  26. 2011 Cotton Net Profit at $0.52/lb vs. Water Applied at $9/in Returns Above Direct Costs Inches of Water Applied per Acre

  27. 2011 Returns Above Direct Costs at $0.90/lb vs. Water Applied at $15/in Returns Above Direct Costs Inches of Water Applied per Acre

  28. 2011 Cotton Net Profit at $0.90/lb vs. Water Applied at $15/in Returns Above Direct Costs Inches of Water Applied per Acre

  29. What Does It Take To Apply 20-25 Inches of Irrigation? * Assumes 125 acre pivot and irrigating season from April 15 to September 15

  30. Conclusions • In 2011 with virtually no sub-soil moisture or rainfall during the growing season, it took at least 4 gpm/acre to make a profitable cotton crop. • Long term analysis shows that systems with the ability to deliver less than 3 gpm/acre would be more profitable cutting irrigated acreage back to that level. • Irrigation profitability is more sensitive to lower cotton prices than higher energy prices. • Expected price level for 2013 would indicate that profitable irrigated yields are still attainable.
