dc.description.abstract |
Abstract In California, the application of compost has been proposed as a management strategy to increase forage production and soil carbon sequestration in semi-arid rangelands. However, given semi-arid rangeland’s highly variable climate, having a holistic knowledge of the impacts of composting practices is imperative for sustainable management. Arbuscular mycorrhizal fungi (AMF) are known to confer many benefits to their vascular plants symbiotes, largely through nutrient acquisition, and have also been proposed to be important to manage in agricultural systems. The body of knowledge surrounding the influence of compost and rainfall variability on AMF, however, is very limited. The purpose of this study is to explore the AMF-plant relationship with the application of fertilizer or compost across a precipitation gradient. Our results show that AMF colonization under compost treatment alone was not affected, but in combination with high precipitation, AMF colonization was significantly depressed when compared to the ambient precipitation. Additionally, AMF colonization negatively correlates with plant root biomass under the same conditions, suggesting that plant hosts reduce C delivery to AMF under low stress and high resource conditions. |
