Economics of Sourcing Cellulosic Feedstock for Energy Production
No full textThis study investigates the economics of supplying wheat straw and corn stover within 100 mile radius of a potential new biorefinery in southeast North Dakota. In particular, straw and stover total delivery costs, potential straw and stover supply sites and least cost transportation routes are identified using a linear programming transport model and a GIS (Geographic Information Systems) mapping system. We show that USDA/NRCS (Natural Resources Conservation Service) future crop residue removal rate policies will be important for determining whether it is economically viable to harvest crop residues as potential feedstock for energy generation. Increase in residue removal rates narrow the size of residue supply areas and consequently result in lowering total transportation costs. There is an economic tradeoff between residue collection density and distance from the biorefinery. Most wheat residues are highly concentrated in the north, some distance from the biorefinery. Relying solely on wheat straw for supply needs require longer transportation distances which increases total cost. Using a combination of wheat and corn residues lowers total transportation costs. Since most wheat/corn residues are densely concentrated in north/south, regional highways would likely be the routes used often to transport the residues, as compared to interstate highways. Increased traffic volumes due to the hauling of crop residues would require additional investment in improving road conditions.Wheat Straw, Corn Stover, Density, Transportation Cost, GIS, Community/Rural/Urban Development, Crop Production/Industries,
A Mary Perks Book #703
No full textApparently Perks Publishing is the successor to American Crayon's Mary Perks series; the latter name appears on the back cover, but not on the title page. One of four bunny stories included is TH. The telling pays attention to some often overloked dynamics. Mr. Hare is careful to give judge Mr. Fox plenty of distance when the two deal with each other. Mr. Fox hopes there will be a prize that he will hold. Binding has been restapled by someone. The version and art here are not those included in (More Than 30 of) American Childhood's Best Books of 1942 or Ten Treasured Tales of 1943.John Sherman Bag

Deterritorialize Yourself! (Four Meta-Musical Vignettes for John Rahn)
No full textI made my first deep dive into both Deleuze and Guattari and J.K. I Randall’s work at around the same time, and through the same source: John Rahn’s seminars on analytical personae and critical theory at the University of Washington in the mid-2000s. It was also in one of these seminars that I first began thinking seriously about how one might go about critically, analytically, theoretically, and politically engaging musical improvisation, as well as, more generally, how to think musically: that is, how to make thinking about music be more like music.1 In order to clarify this last point, we might read four statements of John's alongside one another:
1. All discourse is “committed” to forming the world that it is about, so that it behooves the musician to make discourse about music like music, at least in the essential quality of rich particu-larity, and perhaps in all five of Nelson Goodman’s “symptoms of the aesthetic” . . . : semantic density, syntactical density, relative repleteness, exemplification, and multiple and complex reference.2
2. At the in-time extreme is an obsessive concern for the way in which, at every musical time, events immediately following that time grow out of events preceding that time. Such an explanation would consist of as many explanations as there are moments of musical time in a piece . . . plus an explanation of the way all so-experienced piece-moments integrate into the entire piece.3
3. [following a select list of Heraclitus aphorisms] Musicians, he is speaking to us! The vagabonds of the night, the magicians, the bacchantes, the inspired! Clearly this is a different voice. . . . Music flows, and swirls madly.4
4. The advantage of semigroups and monoids over groups as a general model for machines is that not all machines can run backwards. Indeed, if we want to model musical acts as taking place in irreversible time, we will need to escape groups and inhabit monoids.5
Among many other take-aways, these maxims suggest to me a tem-poral effervescence, a commitment to understanding (and describing) music from within the ongoing practice of its enactment, a productive conflation of rational and mystical, and an attitude toward trans-formational thinking that escapes both the ontological fixity of Being and the formalist apparatus of homomorphic group functions.6 It is important to note that John in no way is taking a hard line with any of the positions articulated or implied in these quotes; each is intended as an image of thought, a provocation to get us thinking about how we think about music, to imagine other perspectives and refine the ones we’re already engaged in. Time and change (and discourse about time and change): these are the themes that have animated the way I think about doing music theory.
What follows are four loosely related meta-musical vignettes, nominally about theorizing music-improvisation (and, to a degree, about Deleuze), but ducking and weaving through many ancillary themes, all rhizomatically connected, but also all forming a single quasi-improvisational narrative.Full Tex
Ten-Year Assessment Encourages No-Till for Corn Grain and Stover Harvest
No full textDeveloping a bio-economy by harvesting crop residues from highly productive corn (Zea mays L.) cropping systems requires science-based management decisions to maintain or enhance grain yield and soil, water, and air resources. Which tillage and stover harvest practices are best for accomplishing these goals? Continuous corn grain yield response to either no-till or chisel plowing with two stover harvest rates (3.4 or 5.1 Mg ha−1 yr−1) was evaluated for 10 yr in central Iowa. Each tillage and stover removal combination was replicated four times. Year-to-year variation affected grain yield more than tillage practice (0.2 Mg ha−1) or stover removal (0.1 Mg ha−1). Grain yields were not statistically different (p = 0.33) between tillage systems. Including machinery costs made return on investment for chisel plow and no-till equivalent even though no-till yields were numerically lower. Net stover income per megagram was US4 greater at the 3.4 versus 5.1 Mg ha−1 harvest rate because of more efficient harvesting. Among the four practices, no-till with 3.4 Mg ha−1 stover harvest met multiple goals, including providing acceptable corn grain yields, positive net income per megagram stover, and sufficient residues to protect the soil.This article is published as Obrycki, John F., John L.

Corn Stover Harvest, Tillage, and Cover Crop Effects on Soil Health Indicators
No full textMonitoring soil health indicators (SHI) will help ensure that corn (Zea mays L.) stover harvest is sustainable. This study examines SHI changes after 5 yr of growing continuous corn with either chisel plow or no-tillage practices and harvesting 0, ∼35, or ∼60% of the stover. Two no-tillage treatments with a cereal rye (Secale cereale L.) cover crop and stover harvest rates of ∼35 or ∼60% were evaluated. All eight treatments were replicated four times in a randomized complete block design at an 11-ha site in Boone County, IA. Soil samples were collected following grain and stover harvest from 0- to 5- and 5- to 15-cm depth increments. Particulate organic matter C (POM-C) decreased when stover was removed or the soil was chisel plowed. No-till with 0% stover removal had 10 mg g–1 POM-C in the 0- to 5-cm soil layer, which was 1.9-fold higher than in other treatments. Potentially mineralizable N (PMN) was greater under cover crop treatments. Average PMN values were 56.9 and 45.5 µg g–1 PMN for no-till with cereal rye at 0- to 5- and 5- to 15-cm depths, respectively, compared with 17.5 and -3.7 µg g–1 PMN for the same no-till treatments without cereal rye. Other soil properties did not respond to increasing levels of stover removal. At this location and at the studied removal rates, 5 yr of harvesting corn stover did not decrease soil health, but POM-C data suggest that changes may be occurring. Long-term monitoring should continue to assess corn stover harvest sustainability.This article is published as Obrycki, John F., Douglas L. Karlen, Cynthia A. Cambardella, John L.
