Jessica Hollever
Farm Sustainability Services
Farm Sustainability Services Senior Specialist

Jessica has always been connected to the agricultural industry after growing up on a dairy farm on the plains of North Otago and South Canterbury, although she loves the land and agriculture she got enough dairy experience growing up to know to not fall in love with a dairy farmer.

While at University of Otago, Jessica had a summer internship at Environment Canterbury in their water quality team. After graduating in 2015 with a Bachelor of Science, Jessica travelled to parts of Canada and America.

With some travelling under her belt, it was time to return home and find a job she could be passionate about. Since joining Ballance in September 2016, she has returned to her roots in the agricultural industry and loves providing support to farmers, and helping them to farm within limits due to the ever increasing regulations.

Lisa Adams
Farm Sustainability Services
Farm Sustainability Services Specialist

Lisa has always had an affinity for the agricultural industry after growing up on a Sheep and Beef Farm in the King Country, Waikato.

This passion lead her to Lincoln University to complete a Bachelor of Science (First Class Honours) in Animal Science and Agricultural Science. Her honours project focused on the oestrogenic effects in sheep grazing Lucerne. At university, she met a dairy farmer from the Bay of Plenty and together they have set up home in Mid-Canterbury. Although she refuses to milk cows, she enjoys the farming lifestyle and being involved in their business as they progress through the dairy ranks.

Lisa started at Ballance in July 2017, after working at Fonterra in a customer-focused role. She enjoys working in farm sustainability and helping farmers navigate the challenges that Farming Within Limits present so they can continue to farm for many generations.

Outside of work, Lisa can either be found in the kitchen, exploring the South Island or getting out and about in the outdoors usually with her dog Bo and occasionally also with her farmer -  if she can get him to leave the farm for long enough.

Erica Leadley
Farm Sustainability Services
Farm Sustainability Regional Manager - South Island

Erica lives, breathes and loves everything arable farming. Her passion for the industry and its success, has fostered from growing up in Mid Canterbury on her family’s intense spray irrigated and lamb finishing business. Now living on her partner’s South Canterbury arable property Erica remains very in touch with the pressures of farming businesses.

Driven from a need to understand and report her home farms environmental footprint Erica stepped back from her day to day on farm involvement to upskill in the nutrient management space. This led her to joining the Farm Sustainability team in September 2017. Erica enjoys engaging with farmers, using her practical farm systems knowledge to provide a quality service.

Out of work Erica is never far from a cook book and is planning her next food creation. She loves spending time cooking for and entertaining family and friends. Her love to travel, also ties in quite nicely with her love of food with trips to Italy and Vietnam to gain new skills. Erica will also take up any opportunity she can to be out on the farm, especially doing her part over harvest.
