Farming - 10 years agoBasic Premise: A field was treated as a unit >Tillage was uniform across the field >Seeding involved one variety >Applied one rate of fertilizer >Applied one rate of pesticide >Yields were estimated based on volume
![Page 15: Remote Sensing Seminar - Purdue University€¦ · Items to consider for a Seminar Presentation: • Colors that you can use: Depends on the background • Size of “font” •](https://reader034.vdocuments.site/reader034/viewer/2022042807/5f7c0b923b5a3918cc0c8773/html5/thumbnails/15.jpg)
Farming Today
Basic Premise: Specific variations withinthe field are a potential unit
• Variable tillage by soil type, relief, etc• Adjust seed variety and rates on the go• Adjust fertilizer rate according to soil tests• Apply variable rate of pesticides• Scouting accomplished by walking the fields –
known variations• Remote Sensing images through the season –
scouting, nutrients, drainage, yield, etc.• Yield maps showing variation by location

Farming Tomorrow
Sensors to measure soil and plantcharacteristics to vary inputs
Crop specialty – bred for specific newcharacteristics
Timed release of fertilizer, chemicals, and otherinputs
Variable harvest techniques Improved software for automating management
decisions
Basic Premise: If you can measure it, it’sa potential management unit
