7 pages, via Online journal, Hair fescue (Festuca filiformis) is a tuft-forming perennial grass that reduces yields in lowbush blueberry (Vaccinium angustifolium) fields. Nonbearing year foramsulfuron applications suppress hair fescue, but there is interest in increasing suppression through foramsulfuron use in conjunction with fall-applied herbicides. The objective of this research was to determine the main and interactive effects of fall-bearing year herbicide applications and spring-nonbearing year foramsulfuron applications on hair fescue. The experiment was a 5 × 2 factorial arrangement of fall-bearing year herbicide (none, terbacil, pronamide, glufosinate, dichlobenil) and spring-nonbearing year foramsulfuron application (0, 35 g·ha−1) arranged in a randomized complete block design at lowbush blueberry fields in Portapique and Stewiacke, Nova Scotia, Canada. Spring-nonbearing year foramsulfuron applications did not reduce total tuft density or consistently reduce flowering tuft density, flowering tuft inflorescence number, or flowering tuft seed production. Fall-bearing year pronamide applications reduced hair fescue density for the 2-year production cycle, although additional bearing year density reductions occurred when pronamide was followed by spring-nonbearing year foramsulfuron applications at Stewiacke. Fall-bearing year dichlobenil applications reduced total and flowering tuft density at each site, although reductions in flowering tuft inflorescence number and seed production were most consistent when followed by spring-nonbearing year foramsulfuron applications at Stewiacke. Suppression extended into the bearing year at each site, and dichlobenil should be examined further for hair fescue control. Fall-bearing year glufosinate applications reduced hair fescue total tuft density at each site and flowering tuft density and flowering tuft seed production at Stewiacke. Fall-bearing year glufosinate applications followed by spring-nonbearing year foramsulfuron applications also reduced nonbearing year flowering tuft inflorescence number and bearing year hair fescue seedling density at Stewiacke, indicating that this treatment may reduce hair fescue seedling recruitment at some sites. Fall-bearing year terbacil applications did not suppress hair fescue and are not recommended for hair fescue management in lowbush blueberry.

7 pages, via Online journal, The mid-nineteenth century Hudson River School of painting reflects artists' views of American paradise, a glorified Hudson River landscape where the disappearing wilderness, agriculture, and human settlements coexisted along the river in perfect harmony. The romantic, peaceful coexistence of nature and humans became an unsustainable illusion as the twentieth century 507 km (315 mi) Hudson River became a major transportation route to the northern and western interior of the United States (figure 1). Like many rivers throughout history, navigation of the Hudson River waters fostered tanneries, paper mills, factories, electrical plants, and other enterprises along its coastline (Rothstein 2019). Rivers, with their abundant water supply and capacity to transport raw materials and finished goods, fueled the Industrial Revolution of the 1800s, and the Hudson River was exemplary in its contributions. Settlements and industries along the Hudson River valley flourished, creating jobs, expanding communities, and bringing economic prosperity to the region and the nation. In its wake, followed an era of industrial pollution that left an ugly mark on the river celebrated for its beauty and pristine waters. In 1984, 321 km (200 mi) of the Hudson River was classified by the US Environmental Protection Agency (USEPA) as the Hudson River PCBs Superfund site—one of the largest in the country.
6 pages, via Online journal, Most agricultural soils are depleted of their soil organic matter (SOM) reserves. A severe loss of SOM content may degrade soil functionality, its capacity for provisioning of essential ecosystem services, and soil health. Therefore, restoration of SOM content in soils of agroecosystems may reverse the degradation trends, enhance ecosystem services (Banwart et al. 2015), and advance Sustainable Development Goals of the United Nations. (Lal et al. 2018a). Increase in SOM content may also partially replace the use of chemical fertilizers and supplemental irrigation, while restoring the environment.
