GPS Soil Sampling Data collected would be :
GPS
map field
boundaries using ATV with GPS mounted to create field outlines and
field areas.
Soil
samples collected from within each ha of field with sampling grid in
same direction as planting.
GPS
soil samples analysed for pcn.
GPS
soil results
presented on field outlines, with deepest colours showing greatest pcn egg numbers: see opposite.
Sampling data normally presented on map.
Eggs from soils with very large egg numbers were speciated to
determine pcn species, ie G.rostochiensis or G.pallida.
Summary: GPS soil sampling for Potato Cyst
Nematode pre potato cropping, GPS soil testing gives fullest picture
of any problems on fields. And at same time soils can be used for
GPS Soil Sampling for fertilizer needs. |
