Pixel cropping is about letting ecology be the guide in the design of productive arable farming systems. Human and non-human ecologies (plant, soil, arthropod, fungi, machine) intersect on the pixel field and must all be given equal weight in the design process. Monocultural farming is highly productive but also the source of copious planetary problems. We need to find new ways of growing crops that have a positive impact on the environment rather than negative. We already know that in-field plant diversity is a promising route to achieve this aim, but what we don’t fully know yet is to what extent ecological complexity can be amplified in an arable agriculture setting without sacrificing production levels. Where is the limit? The pixel cropping project is designed to test the potential of cultivated complexity: can planting crops in a high resolution mosaic of mini-fields (‘pixels’) create a system that produces both good yields and ecological benefits? What is the optimal design for such a mosaic?
