Soil Sensors help variable systems of cultivation

Variable system of irrigation refers to using sensors for determining the portions of land which have sufficient water content so that agricultural activities can be taken according to water availability and plant crops requiring a less amounts of water in other parts where the water content is slim.

Through this methods farmers are encourage to install the sensors and discourage them from dumping water throughout the field, while restricting it to only areas water is needed most. Farmers using such methods have vouched that they are now saving quite a lot of water.

It should be noted that variable systems of cultivation can save as much as fifteen percent of water used over a field. Such saving can bring you two crops annually by which the farmers can benefit monetarily as well. This system is being followed in many states world wide as a new choice for “center-pivot” agricultural system. Apart from saving the scarce water resources, you will be asking yourself a question where is the need to water such portions of farm land where water is not required.

It is estimated that as many as 250,000 “center pivot” agricultural systems are now operating throughout the world and it is left to our imagination as to how much improvement can be brought about. Scientists have pointed out that in the present instance, the variable irrigation system completely relies on the static maps of the farms, without taking into consideration the soil conditions and it is here the soil sensors come into play.

As these sensors will help us to gauge the water content through proper scientific methods, it has become possible to change the way the farm maps look. The soil sensors have been tuned to send the data to the farmers' home computers or the landowners, avoiding their daily or periodical visits to the field. These technological advancements have helped the farmers in a big way.
