GPS yield processing uncovered the following details:
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
>3t/ha. A loss in excess of £180 per acre versus the cost of
preventing this damage.
Lower
yielding area in peninsular of north west field: rabbit damage.
Evaluate lost yield versus cost of prevention.
Heaviest 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
