Development of a corn stover yield monitor
… developed a sensor to measure the mass flow of corn stover through a combine and determine what harvest parameters affected the response of the sensor. A sensor was developed by installing a curved plate behind the rotor discharge beater of the combine to intersect the flow path of the stover …

Techno-Economic Feasibility of Distributed Torrefaction Systems Using Corn Stover Feedstock
… torrefaction biorefining systems using corn stover feedstock to generate value-‐added products. Distributed torrefaction systems have the potential to operate on private agricultural enterprises as well as community-‐scale processing facilities, similar in scale to local grain …

TGA-MS studies of the pyrolysis of corn stover for charcoal production
… (TGA-MS) was used to study the pyrolysis of corn agricultural waste with the aim of improving understanding of the carbonization process. Non-isothermal mass loss data from TGA was obtained for three types of corn waste, cobs, husks, and stalks; and used to calculate proximate analysis in …

Effect of treating corn stover with aqueous ammonia and urea on nutritional value
… the effect of treatment of rectangular bales of corn stover with aqueous ammonia and urea solutions. The stacks were covered with polyethylene sheets for 129 d, after which they were uncovered, aerated and sampled for laboratory analyses.

Effects of AFEX Pretreatment, Denisifcation and Storage on Ethanol Yields of Corn Stover, Switchgrass and Prairie Cordgrass
… with pretreatment, densification and storage of corn stover (CS), switchgrass (SG) and prairie cordgrass (PCG) were addressed as part of a cellulose-to-ethanol process. It is most cost-effective to transport densified cellulosic materials; however this can be cost prohibitive. AFEX pretreatment …

Influence of treating corn stover and sorghum forage with different nitrogen sources on nutritive value for ruminants
… and in vitro dry matter digestibility (IVDMD) of corn (<i>Zea mays</i>) stover treated with different sources of N; 2) digestibility, N utilization and palatabi1ity in sheep fed corn stover treated with different N sources; and 3) fermentation characteristics and nutrient utilization by sheep of …

Characterization of chemical composition, milling properties and carbon dioxide diffusivity resulting from early harvest corn and corn stover
The increasing demand of corn as food and fuel sources has increased the competition for feedstock between livestock and ethanol industries. Developing an effective corn harvesting, storage and utilization system can help reduce the competition for the limited corn supply in the current period. The …

Impact of lignification of corn stover fractions on cell wall degradation by rumen microorganisms and response to ammonia treatment
… wall composition and in vitro degradation of corn stover fractions (leaf, upper stem and lower stem) with advancing maturity and in response to NH; treatment were determined, and possible inhibitory mechanisms of lignin were evaluated. With advancing maturity, IVDMD decreased (P<.001), …

Environmental and economic tradeoffs of feedstock usage for liquid fuels and power production
… fermentation jet (AF-J) fuel from sugarcane, corn grain and switchgrass. We find that ERO₁ 1 for conventional jet fuel from conventional crude oil ranges between 4.9-14.0. Among the alternative fuel pathways considered, FT-J fuel from switchgrass has the highest baseline EROI₁ of 9.8, followed …

Effects of supplement type and forage type on ruminal metabolism and diet digestibility of cattle
… quality forages, including crop residues like corn stover, do not usually meet the animal’s nutrient requirements (NRC, 2000). Corn stover is the fibrous portion of the corn plant left on the field after corn is harvested (i.e. the stalks, leaves, cobs, and husks). Though it is one of the most …

Effects of feeding CaO treated modified wet distillers grains with solubles or corn stover to cattle on performance, carcass characteristics, and ruminal metabolism
Traditionally, feedlot cattle have been fed corn grain; however, recent competition for corn grain for fuel has made it an expensive feed option for cattle producers. Therefore, alternative feeds, like corn co-products, are being considered as energy sources for cattle. Two such co-products are …

Enhancing the feeding value of corn crop residues to improve beef cattle production
Corn has been used in cattle diets for more the 50 years in the United States. However, since 2005 when the “Ethanol Era” started, the demand for corn to be converted in to ethanol has been increasing. The increased demand for corn to be converted into ethanol, led to increased corn prices. When …

Mixing for Suspension of Solids
… to produce downward flow. Sand, wheat straw, corn stover, activated carbon, and activated carbon-sand mixture were studied in this system. Several concentrations of the wheat straw, corn stover, and activated carbon were examined. The liquid level was equal to one tank diameter and the …

Biomass to ethanol : potential production and environmental impacts
… of ethanol produced from three feedstocks; corn grain, corn stover, and switchgrass. A life-cycle assessment approach with an integrated Monte Carlo uncertainty analysis is applied to each of these three bioethanol pathways. Incorporating a Monte Carlo uncertainty analysis within a …

Effects of Corn (Zea mays L.) Stover Removal and Leaching on Soil Test and Whole Plant K Levels in Corn and K Fertilization/High-Input Treatments on Soybean Using Site-Specific Management to Increase Soybean (Glycine max) Production in South Dakota
<p>Potassium is important for crop production. Corn stover removal has the potential to reduce exchangeable and soluble soil potassium (K+) needed for optimal plant growth in addition to grain yield. An experiment was conducted in Aurora, SD, USA, to observe the effects of corn stover removal on …

Effects of replacing corn in beef feedlot diets with chemically or thermochemically treated corn stover and distillers grains on growth performance, carcass characteristics, and ruminal metabolism
… in the U. S. has increased the competition for corn grain to be used as food, fuel, and feed. Although this has increased availability of ethanol co-products, such as modified wet distillers grains with solubles (MWDGS), finding reduced-cost alternative feeds when corn grain and ethanol …

High-performance liquid chromatographic methods for quantitative assessment of degradation products and extractives in pretreated lignocellulose.
… fuels. Herbaceous agricultural residues, such as corn stover, represent a major source of lignocellulosic material with considerable potential for use in biomass-to-ethanol schemes. Currently, the technology for conversion of biomass to ethanol involves dilute acid pretreatment of lignocellulosic …
