  1. Add fertilizer to soil before or after seeding/planting

    A replicated, controlled study in 2010–2012 in an experimental field in Tuscany, Italy (Vannucchi et al. 2015) found that adding fertilizer before sowing seeds did not alter plant density or diversity compared to sowing alone. Plant density did not differ significantly between areas where compost was added to the soil and seeds were sown, and areas where seeds were sown but no compost was added (no data reported). The same pattern was seen for plant diversity (data reported as diversity indices). In October 2010, eight 2 × 1 m boxes were filled with soil collected from a nearby floodplain. Compost derived from household waste was added to four boxes at a rate of 2 kg/m2, while no compost was added to the other four boxes. In November 2010, seeds of 26 native herb species were sown and the soil was raked. Any weeds that grew were removed. The number of plants in each plot was counted in July and October 2011 and plant diversity was assessed in July and October 2011 and 2012.
