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 T_NEW is defined as T_NEW=Q/P_DRY. P_DRY 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.

Claims

1. 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 T_NEW is defined as follows;

T_NEW=Q/P_DRY; and

wherein P_DRY 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.

8. The method according to claim 1, wherein the updated time T_NEW is T′

=Q/P_DRY.

2. 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 P_DRY as the PR (%) of lowest values of the N measurement;

defining an improved Real Schedule Coefficient RSC=P/P_DRY; and

determining an updated time T_NEW=T*RSC.

3. The method according to claim 2, wherein the updated time T_NEW is T′

=Q/P_DRY.

4. The method according to claim 3, wherein the Real Schedule Coefficient RSC≦

1.3.

9. The method according to claim 2, wherein the Real Schedule Coefficient RSC≦

1.3.

10. The method according to claim 2, wherein the Real Schedule Coefficient RSC≦

1.25.

11. The method according to claim 2, wherein the Real Schedule Coefficient RSC≦

1.2.

12. The method according to claim 3, wherein the Real Schedule Coefficient RSC≦

1.25.

13. The method according to claim 3, wherein the Real Schedule Coefficient RSC≦

1.2.

5. 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 T_NEW=Q/P_DRY, wherein P_DRY 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.

6. The irrigation setup according to claim 5, wherein said irrigation device is a sprinkler.

7. The irrigation setup according to claim 6, wherein said irrigation setup comprises a plurality of irrigation devices arranged in an array.
