Following
is the problem statement for my Webquest:
You are a farmer who owns 2000 acres of
farmland. All of your land is irrigatable. Wells
are present on all fields, which are capable of
providing an ample supply of water for
irrigation. In the past you have used,
primarily, furrow irrigation whereby you lay
gated pipe across the end of the field. As the
gates are opened water flows down the rows or
furrows, watering the corn on the way to the end
of the field. You do have one field with a
center pivot. You enjoy it very much, because it
is much less labor intensive and appears to
develop a stronger, healthier plant.
You have also noticed during harvest time, that
the yield seems to be better on the "pivot"
ground. Therefore, you are contemplating the
transition of the furrow system to a pivot
system. The present wells will support either
system. However, the purchase of a pivot system
is a large investment, so you want to be sure
yields are higher with such a system. You decide
to do an official statistical study, to
determine whether the center pivot irrigation
method produces significantly higher yield.
