Drip irrigation hose with emitters having different discharge rates

A method for providing generally uniform irrigation in a field comprising:

• manufacturing a hose having first and second ends, a water supply passage and a plurality of flow regulating channels that are smaller than the water supply passage, the flow regulating channels each comprising:
• a predesignated geometry to provide a desired discharge rate at a given pressure,
• an inlet section comprising one or more openings connecting the water supply passage to that flow regulating channel, and
• an outlet section comprising one or more openings connecting the flow regulating channel to the exterior of the hose,
• wherein the flow regulating channels nearer the first end of the hose have geometries different from the geometries of the flow regulating channels nearer the second end of the hose so that, at a given pressure, the flow regulating channels nearer the second end have a greater discharge rate than the flow regulating channels nearer the first end of the hose;
• placing the hose in the field with the first end of the hose connected to a water supply source;
• and
• introducing water through the hose, whereby the discharge rates of the flow regulating channels are generally uniform over the length of the hose.

A method for providing generally uniform irrigation in a field having different elevations, the method comprising:

• mapping the topography of the field;
• manufacturing a hose having first and second ends, a water supply passage and a plurality of flow regulating channels that are smaller than the water supply passage, the flow regulating channels each comprising:
• a predesignated geometry to provide a desired discharge rate at a given pressure,
• an inlet section comprising one or more openings connecting the water supply passage to that flow regulating channel, and
• an outlet section comprising one or more openings connecting that flow regulating channel to the exterior of the hose,
• wherein the plurality of flow regulating channels have at least two different geometries to provide at least two different discharge rates at the given pressure;
• placing the hose in the field so that the flow regulating channels the produce higher discharge rates are positioned at higher elevations than the flow regulating channels that produce lower discharge rates;
• and
• introducing water through the hose, whereby the discharge rates of the flow regulating channels are generally uniform over the length of the hose.

A method for irrigating a field having different soil conditions, the method comprising:

• manufacturing a hose having first and second ends, a water supply passage and a plurality of flow regulating channels that are smaller than the water supply passage, the flow regulating channels each comprising:
• a predesignated geometry to provide a desired discharge rate at a given pressure,
• an inlet section comprising one or more openings connecting the water supply passage to that flow regulating channel, and
• an outlet section comprising one or more openings connecting that flow regulating channel to the exterior of the hose,
• wherein the plurality of flow regulating channels have at least two different geometries to provide at least two different discharge rates at the given pressure;
• placing the hose in the field so that the flow regulating channels having higher discharge rates are positioned near soil conditions where a higher discharge rate is desired and flow regulating channels having lower discharge rates are positioned near soil conditions where a lower discharge rate is desired;
• and
• introducing water through the hose.
