10. 8/10/2015 What is Drip Irrigation?  Drip is a Production Tool used to precisely and uniformly deliver:  water  plant nutrients  protection chemicals  Drip can maximize crop yield with minimal waste of inputs which equals greater PROFIT !

11. 8/10/2015 What Makes Drip Work?  Low volume water application  Frequent irrigation: every day or several times a day  Application of nutrients through system  Wet only soil about roots  Low operating pressure: 7-15 psi  Highest efficiency & uniformity possible

12. 8/10/2015 The Benefits of Drip: Water Savings Minimize deep percolation Irrigate to match Daily Crop Water Use Uniformity

13. 8/10/2015 Water Use Efficiency Evapotranspiration or ET E T

14. 8/10/2015 Water Use Efficiency Best Described as Unit of Production/Unit of Water E T Typically see 30 to 50%

15. 8/10/2015 Improved Yield, Quality & Earliness Optimal balance of water, air and nutrients enhances top growth over root growth Plant doesn’t wilt so more sugars for growth
