SOWAP (the Soil and Water Protection project) represents a collaborative attempt by industry, NGOs, academic institutions and farmers to address the environmental, economic and social concerns arising from the practice of conventional agriculture and cultivations. Working in the UK, Belgium and Hungary between 2003 and 2006, SOWAP has tested and demonstrated a range of site-specific soil management methods, based on the concept of Conservation Tillage. It looked at the economics of the operations as well as effects on soil erosion and fertiliser run-off. Birds, earthworms and aquatic invertebrates are some of the biodiversity indicators the project measured.
