Irrigation is a practice that came to life millenia ago. It made agriculture possible in inhospitable areas and jumpstarted many desert-bound societies. Irrigation is still used today in many fashions, all over the world. Although irrigation originally used to mean artificially bringing water to a patch of land for agricultural purposes, in more recent times the term irrigation is also used in non-agricultural ways. Lawn irrigation has sprung to life and its purpose is strictly to maintain a garden in places where there might not have been enough water originally. So if you were to look at it this way, irrigation itself hasn’t been changed, mere its intended purpose.
There are many types of irrigation, each suited to their own sorts of land. It all depends on the type of soil, available water, differences in geography, size of the land, available laborers and many other factors. To account for all these factors, there are roughly ten different irrigation methods. Most of these methods are suited for farmland only, since they require methods that might ruin the aesthetics of a garden.
Furrows are shallow channels dug from a higher point. They contain water and lead such water to the farms where the water is needed.
Border check systems require paddocks to be divided into parts. On the paddocks’ slopes, water is flowing to keep the farmland properly watered.
Most other methods include the use of sprinklers, some of which are suited for garden use. These methods would include the use of garden irrigation pumps, which are specially designed to irrigate lawns and gardens.
For both agricultural and garden irrigation, it’s important to have a schedule for when to irrigate. First of all it’s important to know which plants you’re dealing with, to avoid underwatering. This is also why it might be worth considering placing plant that require vastly different amounts of water away from each other. Another way to know whether you’re over or under watering your plants is to check the soil for any clues. This method requires a lot more experience, but as a rule of thumb, any brittle, dry or crumbling soil means it might be time to irrigate again.
