Irrigated cotton growers stand to make substantial savings in fuel and greenhouse gas emissions in tractor operations if appropriate tractor engine and ground speeds are used and tillage depth is kept to the shallowes

Lifting and moving water around farms with pumping systems for irrigation consumes plenty of energy as water is a heavy liquid. Every litre of water has a mass of one kilogram.

A pump efficiency trial at Goondiwindi has highlighted the importance of testing individual pumping set-ups to identify the optimum operating point to achieve maximum efficiency.

Excessive wheel slip and engine speed can waste fuel.

Pumps are simple machines that turn pump shaft rotational speed and torque into fluid energy in the form of elevation, velocity and pressure energies.
