Importance of using GIS Software, GPS Importance of using GIS Software, GPS Hardware, and Site Specific Data Hardware, and Site Specific Data
Management for farm managementManagement for farm management
• Create a detailed picture of a farm operation
• More accurately apply fertilizers and pesticides
• Improve productivity and efficiency
• Decrease liability
Variable Rate Fertility
Recommendation
Satellite and Aerial Imagery
Soil Type Data
Consistent Field Boundaries
Soil Test Points
Yield Monitor Data

Accurate Application of Accurate Application of Nutrients by Usage of ImageryNutrients by Usage of Imagery
By using aerial and satellite imagery to determine nutrient deficiencies, you are able to apply the correct amount of nutrients to the appropriate area as determined in the imagery.
Productivity and Efficiency Productivity and Efficiency AnalysisAnalysis
By recording such information as: • Planting Info• Harvest Info• Tillage Info• Scouting• Manure Applications• Fertilizer Applications • Pesticide Applications• Pest Infestation Areas
Farmers are able to analyze recorded data and therefore improve productivity and efficiency.
Decreasing LiabilityDecreasing Liability
• By keeping accurate records of farming operations, analyzing the recorded data, and making sound management decisions, farmers will be able to decrease liability in their operations.
Early AgricultureEarly Agriculture
• PAST-Mechanical Revolution• As agriculture became mechanized,
farmers began to treat “whole-fields” as the smallest management unit
• -Ignores in-field variability• -Results in over and under
application in certain parts of the field
Technological RevolutionTechnological Revolution• PRESENT/FUTURE• -Precision Farming addresses the fact that
small areas of the field are treated as individual management units/areas

Crop Management LevelsCrop Management Levels
What level (resolution) of crop mgmt is feasible?
By Plant?
By Field?
By Mgmt Zone?
By Small Areas?
Implementation of All ThreeImplementation of All Three
Acquire an accurate field boundary!
Drive around the perimeter of the field with a good DGPS unit
Draw (Digitize) the perimeter of the field using a GEOREFERENCED AERIAL PHOTO
(1 meter resolution or less) with an appropriate GIS Software application.

Yield Monitor DataYield Monitor Data
Yield Monitor
Measure flow of grain while recording Latitude and Longitude.
Soil SamplingSoil Sampling
64 Soil Samples
Plot the points of soil samples while in the field, using a GPS receiver.
Software ApplicationSoftware ApplicationSoftware is used as a “glue” for all of the information collected and hardware used. Allowing the different hardware and data to interact with each other.
ConclusionsConclusions
By implementing GIS Software, GPS Hardware, and Site Specific Management, farmers are able to: minimize variability and financial losses, increase profits and productivity, all while keeping accurate and detailed records of farm operations and procedures.
