Precision Agriculture |
This unit was developed under the assumption that most schools would not have access to the sophisticated tools used in precision agriculture. Therefore the activities make use of the web, computer programs that you can download for free, and activities that demonstrate PA techniques without the tools. Teacher's that can gain access to PA technologies from the agricultural community or local colleges are encouraged to expand the activities beyond those suggested. The teaching outline includes Web links for use by teachers and students as additional resources.
