LEPA and LESA are alterations on a center pivot where the sprinklers are moved much closer to the ground, the spacing between sprinklers is reduced (more sprinklers), and water is emitted at very low pressures. It saves water (18%), it saves energy (less water pumped and pumped at a lower pressure), and it helps growers get better yields especially in areas where water is limiting. However, it has an increased propensity for runoff, and the sprinklers operating below the top of the canopy can require some management changes. In many cases energy savings alone can pay for the increased costs of the additional sprinklers and drop hose. However, the largest profit potential lies in the ability to get improved yields in areas that are water short or have large water losses to wind drift and evaporation.

Step by step instruction on how to use a pressure chamber as a tool to help you schedule irrigation in wine grape vineyards. Dr. Alexander Levin walks through the steps of using a pressure chamber to measure leaf water potential and stem water potential. Part 2 of 2
How to use a pressure chamber as a tool to help you schedule irrigation in wine grape vineyards. The two most important questions you need to answer for irrigation scheduling are “How much?” and “When?” The pressure chamber is an important tool that can be used to determine when you should irrigate....
