Measured Irrigation for Smallholders – Consume 50% less water using a bucket and a steel pipe.
I have recently posted a new YouTube video “Measured Irrigation for Smallholders – Consume 50% less water using a bucket and a steel pipe”. It is important that this video is seen by thousands of poor farmers in developing countries.
It would be greatly appreciated if you could LIKE and SHARE the video.

The most commonly used scheduling method is programmed scheduling but this method wastes a lot of water because it does not respond to the prevailing weather conditions. By upgrading from programmed irrigation scheduling to measured irrigation scheduling, water consumption may be reduced by 50% or more without affecting the yield. The cost of upgrading to measured irrigation is just the cost of a bucket (or evaporator) and a steel pipe
The supporting documentation “Measured Irrigation for Smallholders” can also be downloaded from the Measured Irrigation website www.measuredirrigation.com.au
Any comments would be greatly appreciated.

7 年Hi Bernie, This is a clever application of the Class A pan evaporator for calibrating water delivery to plants. I believe the key component here is the slotted pipe for water front detection. While there is a relationship between daily evaporation from a Class A pan and crop ET, it gives no indication of the depth of wetting front in the soil. The required depth of wetting front will vary considerably with plant growth stage and rooting depth, thus some knowledge of this is needed by the user. Also the volume of water needed to advance the wetting front will vary with soil type. Are you familiar with Richard Stirzaker's wetting front detector device? Advance of the wetting front in soil causes a rod in the device to pop up above ground indicating visually when enough water has been applied to the rooting zone. This detector requires no pan evaporator or control emitter. It indicates depth of watering via rainfall or irrigation. I learned of the device in "Out of the Scientist's Garden" but I have no relation with Stirzaker. Thanks for sharing this.
