1. Economic Evaluation of Automatic Heat Detection Systems in Dairy Farming

Although heat detection makes a relevant contribution to good reproduction performance of dairy cattle, available studies on the economic evaluations of automatic heat detection systems are limited. Therefore, the objective of this article is to provide an economic evaluation of using automatic heat detection. The effect of different heat detection rates on gross margin is modelled with SimHerd (SimHerd A/S, Denmark). The analysis considers all additional investment costs in automatic heat detection.... J.

2. An Economic-Theory-Based Approach to Management Zone Delineation

In both the academic and popular literatures on precision agriculture technology, a management zoneis generally defined as an area in a field within which the optimal input application strategy is spatially uniform.  The characteristics commonly chosen to delineate management zones, both in the literature and in commercial practice, are yield and variables associated with yield.  But microeconomic theory makes clear that economically optimal input application strategies...
