## 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.

## Claims

### Claim 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 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.

### Claim 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 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.

### Claim 3 (depends on 2)

The method according to claim 2, wherein the updated time TNEW is T′=Q/PDRY.

### Claim 4 (depends on 3)

The method according to claim 3, wherein the Real Schedule Coefficient RSC≦1.3.

### Claim 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 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.

### Claim 6 (depends on 5)

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

### Claim 7 (depends on 6)

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

### Claim 8 (depends on 1)

The method according to claim 1, wherein the updated time TNEW is T′=Q/PDRY.

### Claim 9 (depends on 2)

The method according to claim 2, wherein the Real Schedule Coefficient RSC≦1.3.

### Claim 10 (depends on 2)

The method according to claim 2, wherein the Real Schedule Coefficient RSC≦1.25.

### Claim 11 (depends on 2)

The method according to claim 2, wherein the Real Schedule Coefficient RSC≦1.2.

### Claim 12 (depends on 3)

The method according to claim 3, wherein the Real Schedule Coefficient RSC≦1.25.

### Claim 13 (depends on 3)

The method according to claim 3, wherein the Real Schedule Coefficient RSC≦1.2.
