But Gueberts yield monitor
showed surprisingly high numbers this fall, and his thoughts have returned to where his crops are going to go.
data, collected at harvest with an AgLeader system (AgLeader Technology, Iowa, USA) linked to a differentially corrected global positioning system (GPS), were available for 38 of the 64 wheat crops grown on the farm during the study period.
"Indeed, one of our independent adjudicators, Rob Forrest, who was with me on the combine at the time, had to take a picture of the yield monitor

The hay yield monitor
(Model 880) of Harvest Tec USA was installed on a large square baler (Claas 3000) to record the harvested yields.
units that track bushels per acre during harvest, range from $6,000 to $10,000.
A yield monitor
system is a good example of an IDI because it has both sensors and controllers.
Corn grain yields were measured and spatially located by a combine equipped with a calibrated yield monitor
and differentially corrected global positioning system (GPS).
By attaching a yield monitor
and data logger to mechanical grape pickers fitted with a global positioning system (GPS), it has been possible to construct yield maps of vineyards.
According to the firm's quarterly Rent and Yield Monitor
, office rents nationally have fallen by an average of 10.9 per cent while traditional office centre rivals such as the City of London and the West End have seen even bigger drops of 12.6 per cent and 21 per cent respectively.
In his combine, Uphoff has a yield monitor
