Abstract Quantifying changes in soil organic carbon (SOC) stocks and other properties is essential for understanding how soils will respond to land management practices global change. Although they are widely used, comparisons of SOC at fixed depth (FD) intervals subject errors when bulk density or matter occur. The equivalent mass (ESM) method has been recommended lieu FD assessing mineral soils, but ESM remains underutilized rarely used properties. In this paper, we draw attention the...
Terrestrial enhanced weathering (EW) through the application of Mg- or Ca-rich rock dust to soil is a negative emission technology with potential address impacts climate change. The effectiveness EW was tested over 4 years by spreading ground basalt (50 t ha-1 year-1 ) on maize/soybean and miscanthus cropping systems in Midwest US. major elements carbon budget were quantified measurements eddy covariance, flux, biomass. movement Mg Ca deep soil, released weathering, balanced corresponding...
Abstract Perennial crops have been the focus of bioenergy research and development for their sustainability benefits associated with high soil carbon (C) reduced nitrogen (N) requirements. However, perennial mature over several years can be negated through land reversion. A photoperiod‐sensitive energy sorghum ( Sorghum bicolor ) may provide an annual crop alternative more ecologically sustainable than maize Zea mays that easily integrate into rotations perennials, such as miscanthus...
Abstract In the age of biofuel innovation, bioenergy crop sustainability assessment has determined how candidate systems alter carbon (C) and nitrogen (N) cycle. These research efforts revealed perennial crops, such as switchgrass, increase belowground soil organic (SOC) lose less N than annual like maize. As demand for increases, land managers will need to choose whether invest in food or fuel cropping systems. However, little focused on C cycle impacts reverting purpose‐grown crops back We...
Abstract Bioenergy production often focuses on the aboveground feedstock for conversion to fuel and other materials. However, belowground component is crucial soil carbon sequestration, greenhouse gas fluxes, ecosystem function. Roots maximize marginal lands by acquiring resources mediating processes through interactions with microbial community. This world challenging observe quantify; however, there are unprecedented opportunities using current methodologies bring roots, microbes, into...
Globally, soils hold approximately half of ecosystem carbon and can serve as a source or sink depending on climate, vegetation, management, disturbance regimes. Understanding how soil dynamics are influenced by these factors is essential to evaluate proposed natural climate solutions policy regarding net balance. Soil microbes play key role in both fluxes stabilization. However, biogeochemical models often do not specifically address microbial-explicit processes. Here, we incorporated...
ABSTRACT Plant strategies to acquire nutrients from limited environments help shape ecosystem carbon (C) and nitrogen (N) cycling response environmental change. The effects of plant on dynamics are largely uncharacterized in bioenergy agroecosystems, where the impacts could determine bioenergy's ability meet its sustainability goals storing C reducing N loss. We used FUN‐BioCROP (Fixation Uptake Nitrogen‐Bioenergy Carbon, Rhizosphere, Organisms Protection), a plant–microbe interaction model...
Abstract Bioenergy could help limit global warming to 2°C above pre‐industrial levels while supplying almost a fourth of the world's renewable energy needs by 2050. However, deployment bioenergy raises concerns that adoption at meaningful scales may lead unintended negative environmental consequences. Meanwhile, full consolidation industry is currently challenged sufficient, resilient, and resource‐efficient biomass supply an effective conversion process. Here, we provide comprehensive...
Cellulosic biofuel production is expected to increase in the US, and targeted establishment of agriculture marginal lands would reduce competition between biofuels food crops. While poorly drained, seasonally saturated lowland landscape positions are for row crops switchgrass (Panicum virgatum L.), it unclear whether species-diverse tallgrass prairie yield suffer similarly lowlands. Prairie yields typically as graminoids become more dominant, but uncertain this trend due greater aboveground...
Abstract Tallgrass prairie restorations can quickly accrue organic C in soil and biomass, but the rate of accumulation diminishes through time is highly variable among more mature prairies. Long‐term carbon ( SOC ) prairies has been linked to edaphic factors such as texture, moisture, content, it unclear how these affect ecosystem processes that are responsible for observed differences rates older We measured belowground plant pools fluxes within 27–36‐year‐old restored tallgrass order...
Abstract Biofuel feedstocks grown on marginal lands, such as those that experience ephemeral waterlogging, reduce interference with food agriculture. As early‐season extreme precipitation events in the U.S. Midwest continue to increase, waterlogging tolerance may play an important role productivity of annual biofuel cropping systems. We assessed establishment and yield photoperiod‐sensitive sorghum [ Sorghum bicolor (L.) Moench] maize ( Zea mays L.) after rainfall central Illinois. used...
Abstract Understanding agroecosystem carbon (C) cycle response to climate change and management is vital for maintaining their long-term C storage. We demonstrate this importance through an in-depth examination of a ten-year eddy covariance dataset from corn–corn–soybean crop rotation grown in the Midwest United States. Ten-year average annual net ecosystem exchange (NEE) showed sink −0.39 Mg ha −1 yr . However, NEE 2014 2015 corn was 3.58 2.56 , respectively. Most loss occurred during...
