Ten most frequently studied conservation land management interventions (1984–2014). The figure shows notable increases in the absolute number of studies occurred between 2008–09 and again between 2011–12. In particular, from 2011 to 2012, the number of assessments of mulching increased c. 4.5-fold (21–91), organic fertiliser increased c. threefold (19 to 69) and studies measuring the impact of alternate tillage regimes almost doubled (29–57)
