Soil Moisture Sensors and Precision Agriculture

The video discusses precision agriculture technologies, focusing on soil moisture sensors developed at the University of Georgia. These sensors help optimize irrigation by measuring soil moisture at different depths and transmitting data wirelessly. The technology aims to save water and costs for farmers. Additionally, yield and profit mapping tools are introduced to help farmers make informed decisions, highlighting areas of profitability within fields. The sensors are expected to be commercially available by 2015.

What is one of the main goals of precision agriculture technologies for Georgia farmers?

• To eliminate the use of fertilizers

• To increase the number of crops grown

• To reduce the need for farm labor

• To optimize farm output with fewer inputs

Why are soil moisture sensors important for irrigation in Georgia?

• They help in understanding soil water conditions and variability

• They ensure uniform water distribution across all fields

• They help in predicting weather patterns

• They increase the speed of water absorption

What is a unique feature of the soil moisture sensors developed at UGA?

• They measure soil moisture at three unique depths

• They are made from biodegradable materials

• They require no maintenance throughout the year

• They can be powered by solar energy

How do the new soil moisture sensors transmit data?

• Using a mobile app directly

• Through a wired connection to a local server

• Via a low power radio to a web server

• By sending signals to a satellite

What is the estimated water savings when using the new soil moisture sensors?

• 30 to 40 percent

• 20 to 30 percent

• 10 to 20 percent

• 5 to 10 percent

What additional technology is being developed alongside soil moisture sensors?

• Genetically modified seeds

• Variable rate irrigation technology

• Automated pest control systems

• Solar-powered tractors

What is the purpose of yield sensors in precision agriculture?

• To measure the height of crops

• To generate yield maps

• To monitor pest activity

• To calculate soil pH levels

How do profit maps differ from yield maps?

• Profit maps highlight pest-infested areas

• Profit maps show the cost of seeds

• Profit maps indicate the profitability of different field areas

• Profit maps display the water usage

What percentage of a field is typically found to be unprofitable according to profit maps?

• 30 percent

• 40 percent

• 20 percent

• 10 percent

What is the main benefit of precision agriculture according to Dr. Velitas?

• It brings farming into the information age

• It increases the size of farms

• It reduces the need for human labor

• It eliminates the use of pesticides
