Abstract
A method for determining irrigation time across an area with a predetermined size S and based on desired precipitation quantity Q and precipitation rate P. The irrigation setup has a fluid output LPH≧S*P. The new irrigation time TNEW is defined as TNEW=Q/PDRY. PDRY is a representative sampling precipitation average based on an indicative percentage PR of lowermost precipitation measurements selected out of a plurality of precipitation measurements taken across the area S.
Claims13
A method for determining irrigation time across an area with a predetermined size S, based on desired precipitation quantity Q and precipitation rate P;
- wherein the irrigation setup has a fluid output LPH≧S*P;
- wherein the new irrigation time TNEW is defined as follows:
- TNEW=Q/PDRY;
- and
- wherein PDRY is a representative sampling precipitation average based on an indicative percentage PR of lowermost precipitation measurements selected out of a plurality of precipitation measurements taken across the area S.
A method for determining irrigation time across an area with a predetermined size S, said method including the steps of:
- providing a desired precipitation quantity Q and a desired precipitation rate P across the above area;
- determining a desired irrigation time T=Q/P;
- determining an initial fluid output LPH′=S*P;
- choosing, from a variety of available irrigation arrangements, an irrigation arrangement with a minimal fluid output LPH≧LPH′;
- obtaining a plurality N of measurements across the area S including;
- choosing a percentage indicator PR (%);
- obtaining PDRY as the PR (%) of lowest values of the N measurement;
- defining an improved Real Schedule Coefficient RSC=P/PDRY;
- and
- determining an updated time TNEW=T*RSC.
An irrigation setup for irrigating an area with a predetermined size S, said irrigation setup being configured for providing at least a precipitation quantity Q and a precipitation rate P and comprising at least one irrigation device having a fluid output LPH≧S*P and an irrigation time TNEW=Q/PDRY, wherein PDRY is a representative sampling precipitation average based on an indicative percentage PR of lowermost precipitation measurements selected out of a plurality of precipitation measurements taken across the area S.
