Students will explore technical careers in agriculture and learn how GPS and GIS technologies are used to improve agricultural production.
Geographic Information Systems (GIS): a computerized data management system used to capture, store, manipulate, analyze, manage, and display spatial information
Global Positioning Systems (GPS): a space-based satellite navigation system that provides location and time information in all weather conditions anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites
precision agriculture : an information technology-based site-specific farm management system that collects and responds to data ensuring that crops receive exactly what they need for optimum health and productivity
Global Positioning Systems (GPS) and Geographic Information Systems (GIS) are areas of emerging technology in agriculture. In this lesson students will learn how GPS and GIS technology is used to improve agricultural food production.
GPS and GIS are both used in precision agriculture for many purposes including farm planning, field mapping, soil sampling, crop scouting, and yield mapping. GPS technology also provides tractor guidance and allows farmers to operate tractors and equipment in low visibility situations.
These advanced systems enable farmers to accurately manage their crops by applying the precise amount of pesticides, herbicides, and fertilizers to crops. Farmers can also monitor problem areas in a field where crops may be struggling with weeds or disease. Once farmers have collected important data about their land, GPS technology allows them to precisely navigate their field and manage crops year after year. The precision that comes from using GPS and GIS technology reduces expenses for farmers, increases yield, and produces a more environmentally friendly farm.1
