Innovative Farmers was established in 2012 by the Soil Association with the aim of bringing scientific rigour to on-farm trials co-designed by farmers and researchers. With a focus on sustainability and resilience, groups come together on discrete topics and on-farm trials addressing the topics that matter to them.

Nitrogen is required annually by most crops (except pulses) to achieve yield and quality. Judging how much N to apply is a key part of nutrient management.

On Farm Experimentation (OFE) is increasingly being recognised as having transformative power in improving performance in agricultural systems across the world.
