- Variable-rate fertilizer application allows crop producers to apply different rates of fertilizer at each location across fields. The technology needed to accomplish variable-rate fertilization includes an in-cab computer and software with a field zoneapplication map, fertilizer equipment capable of changing rates during operation and the Global Positioning System (GPS). The fertilizer rate at specific locations within fields is based on the georeferenced field zone map on the in-cab computer.The system includes a vehicle-mounted GPS unit to monitor field locations, allowing the computer to change the application rate between zones. Electronic communication between the in-cab computer and the rate controller on the application machine functions to change the fertilizer rate across the field.

Nebraska Cooperative Extension EC 94-737-DGaseous NH3 enters the heat exchanger and then converted to liquid. Liquid NH3 leaves-the heat exchanger and goes to the flow meter, and then to the flow control valve. The flow control valve is electronically controlled from the computer/controller in the tractor cab. Liquid NH3 goes from the controller to the manifold for distribution to the shanks and injectors.

- LiDAR – Light Detection and Ranging . Basically, this technology involves directing laser beams from an airplane to the earth surface, and measuring the length of time it takes for the laser beams to reflect back to a detector on the airplane. This data can be used to quantity features on the surface such as trees and buildings as well as the actual elevation map of the earth surface.Computer technology is used to segregate the laser returns to first returns (used for features other than the ground surface, such as trees) and bare earth returns used for an elevation map.
- Additional reference GIS layers can be displayed in the Fugro viewer. These layers are available without charges for North Dakota from the ND GIS Hub at: http://www.nd.gov/gis/
- Users can select any point on the map to list the elevation for that area.
- John, We have been working with several partners on LiDAR data collects during2010 and 11 for the james river basin and surrounding areas of ND and SD.Unfortunately none of the data has been delivered yet. We are expecting data to begin showing up in the next 30-60 days. Please check back then.
