Hi-flow unpowered Measured Irrigation controller (HUMIC)

/در /توسط

Omodei, B. 2018. Hi-flow unpowered Measured Irrigation controller (HUMIC). AgroTechnology, 4, 26-30.

The Unpowered Measured Irrigation Controller (UMIC) has a limited flow rate because the magnetic valve is quite small. HUMIC uses a much larger magnetic valve. HUMIC uses an Irritrol 2400 Series solenoid valve with 25mm BSP inlet and outlet. The water supply pressure should be between 69 kPa and 1034 kPa (10 – ۱۵۰ psi). Provided you have a continuous water supply to HUMIC, you can leave your irrigation application unattended for weeks on end.

Unpowered Measured Irrigation Training Manual for Smallholders (more crops per drop)

/در /توسط

Omodei, B. 2018. Unpowered Measured Irrigation training Manual for smallholders (more crops per drop). AgroTechnology, 3, 26-41.

It is assumed that the smallholder is using drip irrigation (either pressurised or gravity feed) on a garden or a small plot of land. Using the Unpowered MI Controller (UMIC), you can upgrade your drip irrigation system so that all your plants are irrigated automatically. You can leave your garden unattended for weeks. This will allow you to become involved in other activities away from the garden; for example, travelling to the market to sell your produce.
Measured irrigation is a new method of irrigation scheduling that responds to the prevailing weather conditions. This means that you use much less water without affecting the yield.

Improvement in crop yield per liter using Measured Irrigation

/در /توسط

Omodei, B. 2018. Improvement in crop yield per liter using Measured Irrigation. AgroTechnology, 2, 8-13.

A gravity feed pilot trial in Adelaide evaluated the crop yield per liter using Measured Irrigation (MI) scheduling compared with programmed irrigation scheduling as recommended by Amiran in Kenya.
The results indicate that for medium soils MI scheduling may improve the yield per liter by more than 100%, and for sandy soils MI scheduling may improve the yield per liter by more than 400%.
The results are for a preliminary trial only, and further independent trials are needed to more accurately estimate the improvement in crop yield per liter for various crops under various conditions.
