Production data refers to information which is collected each year, such as Planting, Application and Harvest.
Each of these operations provide either direct information or allow derivatives to be created that prove useful in analysis and decision making.
Planting and application provide information that can be related to many issues immediately after the operation has taken place.
Examples include chemical application where you don’t have to wait for the pest to die (or not die) to know there is a problem. Or planter problems where you don’t need to wait for emergence before you see a problem.
Yield data is the only way to measure yield spatially. Imagery (NDVI) is qualitative not quantitative and there are no algorithms that convert satellite data to yield no matter what you’re being told.
There are many forms of remote sensing from Satellite, Airborne, UAV and machine crop sensors.
Mostly they do similar things and provide the same solutions at the agronomy and field level.
Satellite offer cheap large coverage and PCT Service use SataMap to deliver data from Landsat and Sentinal.
Airborne is still a favorite of PCT and customers mainly due to the expertise of our provider Specterra Systems and the professional collection services of Rohan Lloyd at ImageAir.
UAV’s are becoming a dime a dozen but the main issues are still quality of data and limitations in the amount of data collected.
Machine based sensors are great in some countries for automated incrop application but is probably risky in most Australian farming systems.
PCT specialise in collection of high quality soil and topographic layers.
Using multi depth Electromagnetic sensors from DualEM, 4 depths of EC are collected and analysed in conjunction with RTK elevation derivative layers and in some case Gamma Radiometrics.
Base data layers are the ‘go to’ data layers to create reliable management zones.
We also survey storages and farm wet or dry with RTK GPS and depth sounding equipment.
