Dewatering structures are a common feature used to identify melt-out till, and the lack of such structures in till could preclude deposition by melt-out.To assess the conditions under which melt-out till can be deposited without forming dewatering structures, I use geotechnical data and a quasi-two-dimensional model of geothermal melt-out. Critical discharge determined from geotechnical data su...

The author identified three Late Wisconsin tills in Logan County in 1956, related them to soils in 1965, and named them the Marysville, Bellefontaine, and Pickrelltown in 1967, but included no correlations, which have since become established and are reported here. The Marysville Till is the youngest, is clay-rich and almost pebble-free, and has a shallow soil (Morley-Blount). Next older (south...

Little is known about the effect of management practices on net global warming potential (GWP) and greenhouse gas intensity (GHGI) that account for all sources and sinks of greenhouse gas (GHG) emissions in dryland cropping systems. The objective of this study was to compare the effect of a combination of tillage, cropping system, and N fertilization on GWP and GHGI under dryland cropping syste...

or no-till. Those who oppose this notion argue that no-till is equated with an abusively high use of herbicides and even genetically modified organisms (GMOs) are synonymous with unsustainable agriculture, with no-till taking all the blame. Unfortunately, both sides are right, and therefore, to get closer to the answer of the initial question, we have to take a deeper look into no-tillage syste...

to be the biggest problem associated with stand establishment. Previous work has indicated that drought Planting rhizoma peanut (Arachis glabrata Benth.) directly into stress, particularly in the 3 mo postplanting is one of grass sod may be practical for producers [e.g., cow-calf (Bos taurus) the main reasons stands fail to establish or establish production, low maintenance roadside or turf sit...

My commentary takes up two points raised by Drs. Torres and Bergner: first, the social context in which humiliation takes place and the way such behavior is normalized; and second, the question of face, and in this context, the loss of face and its impact on identity. For me, the key concern in relation to humiliation is not so much loss of entitlement status, but a loss of identity. Humiliatio...

Case studies are presented of three HIV-infected patients, one heterosexual, one bisexual, and one homosexual, who continued to engage in unsafe sex. Western countries have seen an increase in unsafe sex practices since the early 1990s, raising the specter of a new wave of HIV infections. Increasing rates of sexually transmitted diseases are already being reported in case studies and by the Cen...

Accurately determining productive water use ( i.e. , transpiration T, component of evapotranspiration ET) is crucial to improve ecosystem efficiency (EWUE) and develop water-saving management practices. High frequency (10 Hz) eddy covariance data for the 2016–2017 growing season (November 2016 – May 2017) conventional till (CT) no-till (NT) canola Brassica napus L.) fields were analyzed partiti...
