I am a Grower and I want a tool to water my fields easily because watering tranplants quickly is important to for good establishment

Often, water supply is domestic with low pressure. Therefore, only few stationary sprinklers can be used at a time requiring lots of shifting of sprinklers down a planted area. The result is that to water a newly planted area, a lot of effort and time is used. Watering is not consistent as sprinklers make a round profile and beds are rectangular. They need to overlap creating areas which are watered twice while other sections are missed.

What functionality solves this problem?
