Robin Boom has worked as a self-employed agronomist for the past 32 years, providing independent soil fertility advice to approximately 450 pastoral farming clients through Agronomic Advisory Services. He has a strong understanding of the soil-plant-animal health interrelationships, particularly in livestock farming. He also offers soil fertility advice for maize and kiwifruit production, has conducted various trials for fertilizer and seed companies, and has advised on land reclamation post-mining and land disturbance for two companies as part of his business.

Before this, he worked for the MAF Research division as a field technician in the Agronomy section at Whatawhata Hill Country Research Station for eight years after graduating from Lincoln College. He is currently a member of several organizations, including the New Zealand Society of Soil Science, the New Zealand Institute of Agriculture and Horticulture Science, the New Zealand Grassland Association, the British Society of Soil Science, and the Institute of Professional Soil Science.

Robin grew up in Hamilton but has been involved in pastoral agriculture since leaving school. He has been married to Sally for 30 years, and they have three children in their 20s. Throughout their married life, they have lived in the country on small farm lifestyle blocks. They currently operate a small hill country farm (140 acres) on the edge of Taumarunui, where they run sheep and cattle. Robin enjoys riding classic motorcycles and has a strong Christian faith that motivates him to support charities in third-world countries. Together with his wife, he established The Caring Heart Foundation in India, focusing on providing food for the poorest and setting up sewing workshops and water wells in tribal villages.
