Case Study of GPS Yield Mapping and GPS Crop Yield Data Processing
A Farmer in Essex had been collecting GPS crop yield data for over 5 years for GPS yield mapping the details of high and low areas within fields and farms. But he wants more from his GPS crop yield data than the software was allowing him to process. He wanted to have his GPS yield data processed to highlight the important differences that his yield data shows, to better understand how the data can be used in field management to maximise benefits of GPS mapping services.
GPS Yield Mapping with GPS Crop Yield Data
Processing the GPS Crop Yield Data into GPS Yield Maps highlighted the following:-
- Yield monitors create huge amounts of
GPS data that needs to be
processed.
Exact and useful differences between field cultivations, non
inversion cultivations versus plough within the same field.
- Field
areas around southern edges rabbit & duck grazed, reducing yields by
more than 3t/ha. A loss in excess of £180 per acre versus the cost of
preventing this damage.
- Lower
crop yielding area in peninsular of north west field: rabbit damage.
Evaluate lost yield versus cost of prevention.
-
Heaviest crop yielding areas identified. Suggest GPS soil sampling
to identify fertility of high yielding areas of fields versus low
yielding areas.
- Compile
several years yield maps to identify field areas that consistently
produce heavier yields, medium yields or lower yields. For example
map to right shows a single years data versus average for 3 years
data.
Summary of Case Study of GPS Yield Mapping and GPS Crop Yield Data Processing
Case study of GPS yield mapping from combine harvest yield mapped data and how GPS crop yield data processing can convert the mass of combine yield data into more manageable, understandable maps, that can be used to aid management decision making on farm.
