Appendix A: Student Farm Project

One of the primary aims of the Agricultural Science course that the student should, through personal experience, become aware of good farming practice and should have enough scientific knowledge to understand the scientific principles behind it.

In schools where direct and regular access to a farm is not available, it is advisable that each student, regardless whether he / she comes from a farm or not, should become thoroughly familiar with one farm that has at least one livestock enterprise, preferably dairy and / or beef cattle. Contact should be made as soon as possible and should be maintained for at least one continuous twelve-month period, through regular visits, voluntary work and frequent discussions with the owner/manager.

It is recommended that the student keep a notebook specially for his / her farm visits.

Some points of attention are listed below that might be helpful in stimulating and guiding the student’s natural curiosity.

While there is no requirement for the student to submit a thesis on this project, he / she should, at the end of the course, be able to participate in an intelligent and informed discussion of the points relevant to his/her ‘adopted’ farm.
