This booklet, the first of a two part Lincoln College Farm Budget Manual is revised and published biennially. Whilst no claim is made that the contents are exhaustive, they are quite compreshensive. Users of this manual will note that it is fully metricated even though the agricultural sector has not yet reached that point, but the areas of discrepancy are few. Acknowledgement must be made of the work of Mr B. Brook and Mr B. Bulmer ofr their conscientious work in revising this edition.
