Agronomica Limited
was  incorporated in May 2003.  It is an independent firm, entirely owned by its two founders.  

Within Europe and more widely, public concerns about food safety and quality, demands for more environmentally-friendly farming systems and higher standards of animal welfare are all generating intense pressures both on policy makers and on key stakeholders in the food chain.

So, too, are difficult rural economic and social problems – made even more challenging by the imminent expansion of the EU and the potential impact of further trade liberalisation.

Against this background,  Agronomica has been established by Philippa Guest and John Landell Mills with the aim of providing comprehensive services to private and public sector clients covering:-

The firm’s founders believe that technological innovation is a key enabler of sustainable agriculture and are committed to a science-based approach to evaluating the economic, environmental and social impact of new agricultural technologies and practices.

We are also committed to promoting dialogue and partnership between key stakeholders in the food chain through the sharing of ideas, experience and best practice

Agronomica offers the services of its own core staff plus those of an international network of experts covering the food chain from input supply to food processing and marketing.

As a recently established firm, Agronomica’s main credentials at present are those of its two founders:-
