The Excel program LIMP is used to calculate ETo rates, determine landscape coefficients (KL), estimate evapotranspiration (ETL) of landscape vegetation, and determine irrigation schedules. In addition, there is another program DU that is used to calculate the application rate and distribution uniformity of sprinkler irrigation systems from system evaluation data. It also contains a worksheet on determining distribution uniformity of sprinkler systems. To obtain a copy of the program using English units, click on LIMP_e.
