What are UAVs? Why would a farmer be interested?
UAVs are Unmanned Aerial Vehicles often referred to as drones. They are whattheir creator makes them to be.
UAVs for the purposes of precision agriculture can aid a farmer in assessing crophealth, precisely locate epicenters of pest infestation, aid in fertilizer application
etc. Applications are numerous and continuously are being discovered.
However, this is not the Holy Grail.

What can a UAV do for me?
When used to aid in field analysis, UAS in precision agriculturecan promote a higher field health awareness.
When used in conjunction with good field work, recordkeeping, and test/trial analysis it can be highly useful.

Comparing Zone and Grid Sampling
Zone sampling takes advantage ofapplication history maps or soil mapsfor dispersed sampling.
Grid sampling can promote accurateresults at a granular level, however,are costly in time and expense.
UAV generated maps can takeadvantage of this and merge the
two sampling techniques.
