The impact of crop rotation on soil microbial diversity: A meta-analysis (2016, background): “The historical adoption of crop rotations was largely motivated by the associated yield increase in the cash crop (Bullock, 1992) attributed to enhanced agroecosystem function in terms of increased soil fertility (particularly when leguminous plants are used in rotation), maintenance of soil structu”
Breeding Annual Grain Legumes for Sustainable Agriculture: New Methods to Approach Complex Traits and Target New Cultivar Ideotypes (2015, unknown): “The assumption that crop diversity may have implications for positive roles in ecological and sustainable cropping systems has often been proposed but requires further study (Santalla et al., 2005; Smith et al., 2008).”
Crop rotational diversity enhances belowground communities and functions in an agroecosystem. (2015, background): “At this site, increased rotational diversity has led to increased corn yields, with highest diversity rotation yields 100% greater than monoculture corn (Smith et al. 2008).”
Weed–crop competition relationships differ between organic and conventional cropping systems (2009, background): “…for the apparent increase in crop tolerance to weed competition in the organic systems could involve changes in soil resource quantity, quality or temporal availability that occur with increasing diversification of cropping systems and delayed planting (Liebman & Davis, 2000; Smith et al., 2008).”
Biological Diversity in Agriculture and Global Change (2010, background): “GIS: geographic information system from the interactions with soil nutrient management of varied crop species in rotation (69).”
Corn yield response to winter cover crops: An updated meta-analysis (2017, background): “…early season N was positively correlated with yield increases up to 2.6 Mg ha –1 (1.16 tn ac –1 ) for corn that followed more than one legume WCC (Smith et al. 2008), which could be explained through ecological mechanisms hypothesized for the over yielding capacity of non-N fixing species…”

Wheat improves nitrogen use efficiency of maize and soybean-based cropping systems (2015, background): “…al., 2005; Meyer-Aurich et al., 2006a), decrease in yield potential and increased yield instability (Grover et al., 2009; Katsvairo and Cox, 2000; Lund et al., 1993; Meyer-Aurich et al., 2006a,b; Singer and Cox, 1998; Smith et al., 2008; Stanger and Lauer, 2008; Varvel, 2000; Yamoah et al., 1998a).”
Resilience in Agriculture through Crop Diversification: Adaptive Management for Environmental Change (2011, background): “A growth in production has also been seen in field experiments manipulating diversity in crop rotations (crops, cover crops, and chemical inputs), showing significantly greater corn grain yields with increased diversification over time (Smith et al. 2008).”
Does agricultural crop diversity enhance soil microbial biomass and organic matter dynamics? A meta-analysis. (2014, background): “…relationships between crop yields and crop rotations have been well-established (Copeland and Crookston 1992, Bullock 1992, Gurr et al. 2003, Smith et al. 2008), rotation effects on SOM dynamics, soil microbial populations, and other belowground dynamics remain uncertain (Drinkwater et al.…”
