Cattle grazing increases microbial biomass and alters soil nematode communities in subtropical pastures (2006, background): “However, mammalian grazing for two years in semiarid grassland in Kenya decreased soil microbial biomass in sites of both high and low fertility, despite the fact that grazing stimulated aboveground production in nutrient-rich sites and depressed it in nutrient-poor sites (Sakaran and Augustine, 200”
Factors controlling decomposition rates of fine root litter in temperate forests and grasslands (2014, background): “…root decomposition directly by altering the plant species composition and soil decomposer communities (Bardgett et al. 1998), or indirectly through changes in soil properties such as bulk density and soil moisture (e.g. through trampling) (Sankaran and Augustine 2004; Taboada and Lavado 1988).”
Defoliation and patchy nutrient return drive grazing effects on plant and soil properties in a dairy cow pasture (2009, background): “…have also been shown to affect microbes and animals that control decomposition of dead organic matter in soil (Holt 1997, Bardgett et al. 2001, Sankaran and Augustine 2004, Patra et al. 2005), with consequences on soil nutrient mineralization (Hassink 1992, Frank and Groffman 1998, Frank et…”
Trampling and Spatial Heterogeneity Explain Decomposer Abundances in a Sub-Arctic Grassland Subjected to Simulated Reindeer Grazing (2009, background): “However, waste patches only influence a small proportion of the grazed area (Augustine and Frank 2001), and as herbivory can also have negative effects on plant production and microbial activity (Olofsson and others 2001, 2002; Sankaran and Augustine 2004 ), other mechanisms are also needed to full”
Grazing history effects on above- and below-ground litter decomposition and nutrient cycling in two co-occurring grasses (2008, background): “Moreover, prior grazing history may either accelerate or retard nutrient release from litter by altering the soil environment for decomposition (Shariff et al. 1994; Bardgett et al. 1998; Sankaran and Augustine 2004).”
