BACKGROUND Pretreatment is an essential step in the enzymatic hydrolysis of biomass for bio-ethanol production. The dominant concern in this step is how to decrease the high cost of pretreatment while achieving a high sugar yield. Fungal pretreatment of biomass was previously reported to be effective, with the advantage of having a low energy requirement and requiring no application of addition...

Short harvest window of corn (Zea mays) stover necessitates its storage before utilization; however, there is not enough work towards exploring the fast pyrolysis behavior of stored biomass. This study investigated the yields and the physicochemical properties (proximate and ultimate analyses, higher heating values and acidity) of the fast pyrolysis products obtained from single-pass stover and...

Greenhouse gas (GHG) emissions from crop residue management have been studied extensively, yet the effects of harvesting more than one in a rotation not reported. Here, we measured short-term changes methane (CH4), nitrous oxide (N2O), and carbon dioxide (CO2) response to removal continuous corn (Zea mays L.) (CC) corn–wheat (Triticum aestivum L.)–soybean (Glycine max L. Merr.) (CWS) rotations ...

Iron (Fe) deficiency in humans, particularly pregnant women and children, is caused by inadequate dietary Fe intake a global nutritional problem. Foliar fertilization cost-effective agronomic approach to increase bioavailability the human diet. We evaluated effects of different formulations (Fe-citrate, Fe-EDTA, FePO4, nano-Fe oxide, humic acid (HA) with without Fe) on growth, yield, accumulati...

The potential of conservation practices to maintain soil organic C (SOC) and reduce climate change impacts on yields is unknown. This study aimed validate the DayCent model with observed yield data CQESTR measured SOC in two agroecosystems, predict best sustain under projected change. Data were from a conventional tillage (CT) wheat (Triticum aestivum L.)–fallow rotation without N or 135 kg ha–...

Corn (Zea mays L.) stover, the residue left after harvest, is an abundant biomass source for producing cellulosic ethanol in the United States. Corn has been bred for increased grain yield but not for stover quality for cellulosic ethanol production. Our objective in this study was to assess the feasibility of breeding corn for grain yield and agronomic traits as well as stover quality traits f...

Feedlot performance and mass balance were evaluated on steers fed either 5% untreated corn stover (CON), 20% untreated corn stover (NONTRT), or 20% calcium oxide (CaO) treated corn stover (TRT) when fed with or without saponins (Micro-Aid) in a 3x2 factorial. In both WINTER and SUMMER experiments, ADG, F:G and HCW were improved (P < 0.01) in CON and TRT fed steers compared to NONTRT fed steers....

Dilute H(3)PO(4) (0.0-2.0%, v/v) was used to pretreat corn stover (10%, w/w) for conversion to ethanol. Pretreatment conditions were optimized for temperature, acid loading, and time using central composite design. Optimal pretreatment conditions were chosen to promote sugar yields following enzymatic digestion while minimizing formation of furans, which are potent inhibitors of fermentation. T...

This study investigated the effects of corn stover as a supplemental feed on anaerobic digestion of dairy manure under different hydraulic retention times (HRT). The results elucidated that both HRT and corn stover supplement significantly influenced microbial community and corresponding anaerobic digestion performance. The highest biogas production of 497 mL per gram total solid loading per da...
