Which farm management practice can involve the use of biotechnology?

Embryo transfer represents a farm management practice that directly utilizes biotechnology. This technique involves the surgical removal of embryos from a donor female and their subsequent transfer into the reproductive tract of a recipient female. By leveraging genetic selection and reproductive technologies, embryo transfer allows for the rapid improvement of livestock genetics. It enhances the efficiency of breeding programs by enabling the production of multiple offspring from superior animals in a shorter timeframe.

This practice demonstrates the integration of scientific advancements in reproductive biology and genetics, making it a clear example of biotechnology in animal breeding. Other options, while equally important in farm management, do not inherently involve the manipulation of biological systems at the genetic or cellular level that characterizes biotechnology. Crop rotation, soil tillage, and harvesting are more traditional agricultural practices that focus on crop management and land use optimization rather than genetic or reproductive interventions.
