The LTAR Integrated Common Experiment at Upper Mississippi River Basin-Platteville.

Alternative agronomic practices are needed to address the various climatic, agronomic, edaphic, and water quality related challenges faced by the dairy farmers of the Driftless Area (DA) in the Upper Mississippi River Basin (UMRB). These practices should be innovative in nature, inclusive of regional stakeholders, and sustainable to meet the future food and climate related challenges of Wisconsin agriculture. Here, we outline our Integrated (grazing and cropland) Long-Term Agroecosystem Research Common Experiment at the University of Wisconsin-Platteville Pioneer Farm (UW-P PF) in the UMRB and describe our collaboration in this USDA network.

Effects of combined nitrogen and phosphorus application on soil phosphorus fractions in alfalfa ( L.) production in China.

Nitrogen (N) and phosphorus (P) fertilizers change the morphological structure and effectiveness of P in the soil, which in turn affects crop growth, yield, and quality. However, the effects and mechanism of combined N and P application on the content of P fractions and the transformation of effective forms in alfalfa ( L.) production is unclear.

Key traits for ruminant livestock across diverse production systems in the context of climate change: perspectives from a global platform of research farms.

Ruminant livestock are raised under diverse cultural and environmental production systems around the globe. Ruminant livestock can play a critical role in food security by supplying high-quality, nutrient-dense food with little or no competition for arable land while simultaneously improving soil health through vital returns of organic matter. However, in the context of climate change and limited land resources, the role of ruminant-based systems is uncertain because of their reputed low efficiency of feed conversion (kilogram of feed required per kilogram of product) and the production of methane as a by-product of enteric fermentation.

Management of primary mycotic aneurysms and prosthetic graft infections: an 8-year experience with in-situ cryopreserved allograft reconstruction.

Background: Primary mycotic aneurysms and prosthetic graft infections are traditionally managed by resection of infected vascular tissue and revascularisation with an extra-anatomical bypass. Long-term patency for this method has been reported to be poor with associated high reinfection and limb amputation rates. The aim of this study was to analyse the outcomes of those patients in our department between 2010 and 2018 whom had revascularisation with in-situ arterial reconstruction using cryopreserved allograft as a conduit.

Supplementary calcium ameliorates ammonium toxicity by improving water status in agriculturally important species.

Fertilization of agricultural plants with ammonium [Formula: see text] is often desirable because it is less susceptible to leaching than nitrate [Formula: see text] reducing environmental pollution, risk to human health and economic loss. However, a number of important agricultural species exhibit a reduction in growth when fertilized with [Formula: see text] and increasing the tolerance to [Formula: see text] may be of importance for the establishment of sustainable agricultural systems. The present study explored the feasibility of using calcium (Ca) to increase the tolerance of bell pepper (Capsicum annuum) to [Formula: see text] fertilization.

Outcomes of covered expandable stents for the treatment of TASC D aorto-iliac occlusive lesions.

Introduction: Aortoiliac arterial occlusive disease is frequently encountered in the management of lower limb vascular insufficiency. We report our experience with covered balloon-expandable stents for treatment of TASC D lesions of the abdominal aorta and common iliac arteries.

Methods: A retrospective study of 30 patients who underwent aortoiliac stenting with the Atrium Advanta V12 from March 2010 to September 2012 was conducted.

Controlled release fertilizer increased phytoremediation of petroleum-contaminated sandy soil.

A greenhouse experiment was conducted to determine the effect of the application of controlled release fertilizer [(CRF) 0, 4,6, or 8 kg m(-3)] on Lolium multiflorum Lam. survival and potential biodegradation of petroleum hydrocarbons (0, 3000, 6000, or 15000 mg kg(-1)) in sandy soil. Plant adaptation, growth, photosynthesis, total chlorophyll, and proline content as well as rhizosphere microbial population (culturable heterotrophic fungal and bacterial populations) and total petroleum hydrocarbon (TPH)-degradation were determined.

Short-term biodegradation of petroleum in planted and unplanted sandy soil.

A greenhouse experiment was conducted to determine the effect of microbial populations and biodegradation of petroleum hydrocarbons in Lam. 'Passerel Plus' planted and unplanted contaminated sandy soil. Plant adaptation, growth, photosynthesis, rhizosphere microbial population, and total petroleum hydrocarbon (TPH) degradation were determined.
