ROSENQVISTS MOBILE BOOM IRRIGATION -- A SHORT DESCRIPTION
Today, boom irrigation machines are by far the most flexible mobile irrigation systems on the market. Other technologies such as drip irrigation and solid set small sprinkler systems which are time-consuming to assemble. These systems serve specified fields and cannot be moved without considerable effort. They also involve high investment.
The idea behind a mobile boom system is that you can move your irrigation unit to the fields which need it, when they need it. Crops need an increasing amount of water as their growth accelerates. If you are practicing precision farming, boom irrigation is among the irrigation systems that will deliver the most even and effective application of irrigation. Compared with other technologies such as pipe systems with solid set sprinkler and conventional irrigation machines with big gun sprinklers , boom irrigation proves itself to be the superior mobile irrigation system.
Boom irrigation uses less energy and water per hectare compared with big gun sprinkler machines. This results in greatly reduced irrigation costs compared with big gun sprinkler machines.
