Differential effects of conifer and broadleaf litter inputs on soil organic carbon chemical composition through altered soil microbial community composition
A strategic selection of tree species will shift the type and quality of litter input, and subsequently magnitude and composition of the soil organic carbon (SOC) through soil microbial community. We conducted a manipulative experiment in randomized block design with leaf litter inputs of four native subtropical tree species in a Pinus massoniana plantation in southern China and found that the ...
متن کاملSoil moisture and soil-litter mixing effects on surface litter decomposition: A controlled environment assessment
Recent studies suggest the long-standing discrepancy between measured and modeled leaf litter decomposition in drylands is, in part, the result of a unique combination of abiotic drivers that include high soil surface temperature and radiant energy levels and soil-litter mixing. Temperature and radiant energy effects on litter decomposition have been widely documented. However, under field cond...
متن کاملSoil fauna alter the effects of litter composition on nitrogen cycling in a mineral soil
Plant chemical composition and the soil community are known to influence litter and soil organic matter decomposition. Although these two factors are likely to interact, their mechanisms and outcomes of interaction are not well understood. Studies of their interactive effects are rare and usually focus on carbon dynamics of litter, while nutrient dynamics in the underlying soil have been ignore...
متن کاملPlant Litter and Soil Reflectance
The presence of plant litter on the soil surface influINTRODUCTION ences the flow of nutrients, carbon, water, and energy in Ecological Importance of Litter terrestrial ecosystems. Quantifying plant litter cover is Litter is senescent (or dead) plant material that gradually important for interpreting vegetated landscapes and for decomposes into soil. It is difficult to classify litter beevaluat...
متن کاملSpecies diversity and chemical properties of litter influence non-additive effects of litter mixtures on soil carbon and nitrogen cycling
Decomposition of litter mixtures generally cannot be predicted from the component species incubated in isolation. Therefore, such non-additive effects of litter mixing on soil C and N dynamics remain poorly understood in terrestrial ecosystems. In this study, litters of Mongolian pine and three dominant understory species and soil were collected from a Mongolian pine plantation in Northeast Chi...
