Precision Agriculture Technologies for Dry Area
All kind of measures have been taken to increase the water use of people and industries. But which technologies are available to increase the water use in agriculture and still can rely on better harvests?
We learned form Israel the ‘drip by drip’ irrigation method. Drip irrigation is an increasingly popular way to improve irrigation efficiency over this traditional approach.
This technology disperses water in small, flexible water lines, either above or below ground. In most cases, an “emitter,” or opening positioned at each plant, releases water at a measured rate based on the plant’s need.
These methods have been improved. And with more water issues in the world, the amount of high tech agriculture drop methods has been exploded. Let’s have a look.
Smart Grid Agri Project California, USA
Look at this Smart Grid Project web to wireless controller for irrigation pumps for an agricultural demand response program in Calfornia (USA). Technology and investment in Smart Grid Infrastructure including sensors, smart meters, and monitoring equipment: A case study including results and lessons learned.
Rubicon Water is developing surface irrigation as efficient as drip using an approach ‘high-performance surface irrigation’
The basic principle involves flooding fields at a faster rate and with more limited quantities of water than used by traditional methods.
It seems counter-intuitive, but it works because the speed and precision provided by soil-moisture sensors and automated canal gates means the water doesn’t have an opportunity to run off the field or soak deep into the ground where the crops can’t use it.
Smart Water Monitoring With Your Phone reduces costs to over 90%
MWM developed the Mobile Water Tracker (software and technology) to analyze information from thousands of water meters to improve communication with farmers and water managers,
With a press on the button, the Tracker finds leaks, institutes rate changes, analyzes and send utility managers and farmers better manage support on their water management.
The Mobile Level Tracker allows users to measure water levels with the click of a button. The inaccuracy of the measurement is less than 10 mm when using a metric staff gauge and less than 0.15 inch when using an English staff gauge.
Satellite crop monitoring
The next step, is to equip a drone with a thermal-imaging camera. In partnership with colleagues at NASA and the U.S. Geological Survey, Professor Daniel Howes is working to turn remote-sensing data from satellite imagery into measures of evapotranspiration on farms.
The team is producing satellite photos with 30-meter resolution showing water use by crops in varying color codes. The photos show farmers at a glance which area of a crop needs more or less water. Read more
A Saltwater Greenhouse Grows Vegetables In Deserts
The greenhouse has a cardboard screen at one end with hundreds of small holes in it. Saltwater trickles down from above and evaporates as it meets hot air coming in from outside. The air indoors becomes humid and up to 15 degrees Celsius cooler than normal, while the moisture condensates on the plants, helping them to grow.
At the same time, the greenhouse also has a series of pipes full of cold ocean water. When warm air hits the pipes, droplets form on the surface, which are captured and used for irrigation. Read more
