Basic Principles of Water Irrigation Systems

Before we discuss the various types of water irrigation system available, let us first discuss what irrigation basically mean?
Irrigation can be scientifically defined as the artificial way of applying water to the land or soil. They are basically used on farms to assist growing crops, and are also used in re-vegetation of disturbed soils in dry and hot areas, may be when a particular region is facing a drought. Irrigation can also be defined as the practice of transporting water from one location to the other location under drought. They are usually used on farms to water crops, at home to water gardens and lawns.

The water irrigation system was invented thousands of years ago. Back then, irrigation was done by attentively placed channel and they depend upon the gravity power to push the water. Most of the locations still use this ancient technique.
The main factor a farmer has to think of is how efficiently he can make use of water resource availability. If there is no sufficient water then it results in dead and dry fields while more water can lead to soil erosion and hence destroy the crops. So the farmer has to plan carefully before he starts cultivation.
Most of the farmers make use of modern water irrigation system these days. Some of them are given below.
  • Surface irrigation: In this method, one has to rely on gravitational power to push the water from one location to another. In such extreme cases where gravitational power cannot push the water into the required location, pumps can be used as an alternative.
  •  Seepage Irrigation: It is a type of irrigation, where crops get water from underground resources. These types of irrigation can be expected in such places where there high water table exists.
  • Sprinkler Irrigation: It is a type of irrigation where the water is passed through a series of pipes and then sprinkled over the crops. These sprinklers will be made rotational so that equal amount of water can be sprayed.
  • Drip irrigation system: It is a typical irrigation system, where as the name suggests water falls on the crop drop by drop over the roots directly.

The ancient method of soil probe and feel method to know the moisture content in the soil have been replaced by the new technology called as the soil moisture meter. This instrument determines the moisture level in the soil and hence helps us in efficiently managing water

Uses of Soil Moisture Meter in Agriculture


Moisture is very important for any kind of soil  in order to for good crops. Soil moisture meter is a device which is used to measure the percentage of water content present in the soil. Soil moisture meter is an essential device for any person involved in the field of agriculture and its related fields. This device can measure the moisture content present in the soil and thus give the person an idea of how much amount of water need to be supplied to the plants that are grown at that time. This ensures healthy growth of the plants.Any farmer involved in agriculture or any person who maintains a garden can have a soil moisture meter to measure the humidity of the soil. It is not very costly and is quite a user friendly device for anyone to use it efficiently. When put to use, this device shows different ranges of water content in the soil by color indicators and each color denoting a particular range.There are various models available for the meter and each one of them work on a different principle. There are meters which use electrical resistance blocks and thermal dissipation blocks. A farmer uses a sensor called the electrical resistance block and the latter temperature sensors.

Commercial farmers grow different types of crops on a very large scale. They cannot afford to bear huge losses. For the plants give a better yield  and generate more profit,  maintaining a healthy soil and environment are the main criteria  that should be made available. One of the factors that determines soil health is its dampness. It is very important to monitor the dampness  throughout the life of the plant to make sure that the right amount of water is supplied when it is dry and follow a dry period if the soil dampness has increased sue to some reasons.

Soil moisture meter is a must have device for for any person involved in agriculture or any related field as this device guides  how much and when to water the plants to ensure their healthful development continuity.
