Objective
- To investigate the precision needed for sensing biological
parameters in the landscape including crop residues, soil
nutrients, crop yield (for grain crops and root crops),
and soil moisture.
- To develop machines and assist others in developing machines
for use in precision farming activities.
- To investigate the economics of using variable-rate technologies.
Need or Impact
There is a need for a better understanding of the precision
of sensors used to measure grain flow on combines. The work
from this project gives insight into the confidence of grain
yield measurements from any area in the field. To date, most
data from yield monitors is accepted as absolute when this
is not the case. Farmers will be better informed as to the
precision of the data presented by their yield mapping software.
Project Status
In progress.
