About key messages

Key messages provide a descriptive index to studies we have found that test this intervention.

Studies are not directly comparable or of equal value. When making decisions based on this evidence, you should consider factors such as study size, study design, reported metrics and relevance of the study to your situation, rather than simply counting the number of studies that support a particular interpretation.

Supporting evidence from individual studies

  1. A replicated, randomized, controlled study in 2012–2013 in an irrigated squash field in the Central Valley, California, USA, found more soil-nesting bees in plots with no tillage, compared to deep tillage. Pollinator numbers: More Peponapis pruinosa squash bees emerged from nests in plots with no tillage, compared to deep tillage (11 vs 8 bees/cage). Methods: In August 2012, bee nests were established in 20 plots (3 x 3 x 1.8 m field cages), each of which contained drip-irrigated squash plants. Deep tillage (disking, ripping, and subsoiling: 41 cm maximum depth) was used on 10 of these plots, in autumn 2012. Emerging bees were collected in blue vane traps (26 May–26 September 2013).
