Advanced agricultural techniques employ various methods of using land. Some time back when machines came into popular use in agriculture, folks were eager to create straight rows of plantings as far as the eye could see. They forgot how earlier methods were beneficial to the land being tilled or used to grow things.
Some of these methods included following the contours of the soil, some used natural waterways and found ways to transport stuff from there without changing their course. Center pivot irrigation system belongs to a more recent development in which farming methods turned back to making use of its resources with a view to following their natural character or devise more efficient methods.
The center pivot system does not create ditches and canals which tended to mire plowed and planted land into marsh like consistency. These would have been good with plants which utilized this kind of ground, like rice. However, the temperate zone and most of the agricultural lands in this country need some irrigation but not too much of it.
For instance, the grains that could be grown on soils in this country belong to a family of hardy grass belonging mostly to savannahs or steppes. The use of water is also considered, and there used to be a time when abundance for this concern was thought excellent. And making this a fact became the object of irrigation projects, a matter of more is good, while the best idea is enough works.
Water resources now are better known, and these have underground sources called aquifers. These are the primary things that need to be accessed when any kind of extraction for use on irrigation is needed. That is, without using the natural courses that may be in the surrounding areas.
Usually, for agricultural purposes, water is either extracted from the ground or channeled with any number of methods. Pipes are expensive to use, and are mostly inefficient and even risky when they have to run on or under the ground. Since extraction and channeling are usually combined to make irrigation work here, a better system was soon devised.
This became the center pivot system, which relies on central piped in sources to water plants within a reachable radius. This is an innovation or an evolution of ground based sprinkler systems. Many thought how this was really inefficient and used the method sparingly, although sprinkling is basically a more natural process, an imitation of rain.
Rain is the best way to irrigate plants, that is, when it is not too heavy or work with strong winds. Later on, the concept of rain became the central idea to the dome like system that is being discussed in this article. A dome is above ground and when the water is sprinkled from the top, it become more like natural rain.
Irrigation today then accesses ergonomics, efficiency and friendliness to the environment. These are all modern and current values which has caused less wastage or resources like water. The central pivot sprinklers do not need to load maximum volumes in order to work, but only use a certain amount to precisely address the daily needs of plants within its radius.
