Description

Shallow well jet pumps are practical for wells or reservoirs that require a total pumping lift of less than 5.5 m (18 ft). Industry Highlights. The three main components of the shallow well jet pump are an electric motor, an impeller and a jet assembly. Although a simple centrifugal pump would pump water at this lift, including a jet assembly will greatly increase the discharge pressure and suction. This combination makes the shallow well jet pump suitable for use in farm water pressure systems.

Description

Reports on the results of a series of focus groups with farmers held by Alberta Agriculture, Food and Rural Development to examine whether global climate patterns and more extreme weather events across the Canadian landscape were concerning producers. Discussions focused on the producers' risks, opportunities, and capabilities due to climate change. Also discussed were their views on what support they need in the management of risks associated with climate change.

Description

Dust and harmful gases can cause immediate and long-term respiratory problems. Wearing protective equipment is vitally important when working in a situation where there is the potential for respiratory hazard: working in dusty buildings or fields; entering silos or manure pits; handling mouldy hay; applying pesticides or fertilizers. Depending on the specific hazard, failing to wear the proper respirator, or wearing it improperly, can result in health effects ranging from temporary discomfort to long-term lung problems and even death.

Description

Sarcoptic mange, or barn itch, is a disease caused by the parasitic mite, Sarcoptes scabiei. Mange produced by this mite can be severe because the mite burrows deeply into the skin, causing intense itching. Cattle affected by sarcoptic mange lose grazing time and do not gain weight as rapidly as do uninfected cattle.

Downy brome control in direct seeding systems

Description

Downy brome is a winter annual, grassy weed that is becoming increasingly troublesome in southern Alberta. Its rapid increase in density and distribution on cropland is associated with fall-seeded crops and minimum tillage systems. Key control practices for winter wheat or fall rye include leaving an interval of at least three to four years between fall-seeded crops and adding an oilseed or pulse crop to the rotation. For minimum tillage systems, glyphosate applied in late fall or early spring provides better control than tillage, especially under cool, wet conditions. Higher rates of glyphosate are necessary to control downy brome after heading.

Assessing the carbon content of the AESA benchmark sites from 1998 to 2004

Description

The Alberta Environmentally Sustainable Agriculture Program (AESA) Soil Quality Resource Monitoring Program has provided a data set containing soil organic carbon (OC) values and associated characteristics. These have been used to assess both the total amount, and changes in soil OC at these sites. The program consists of 42 sites distributed throughout the province and covering the major agricultural regions. Each site is intended to represent the ecodistrict where it is located. At each site, upper, mid and lower slope positions were sampled to evaluate the influence of topography on soil. The sites have been monitored since 1998. This monitoring included yield measurements and annual analysis of surface soil. These soil test results, combined with the total soil profile data from an initial pedological investigation, provide a unique opportunity to examine soil OC under a broad range of soils, climate and management practices.

Description

Dugouts provide water for a variety of purposes. They can be used as a source for domestic (household) water supplies, livestock watering, as well as raising fish for enjoyment or profit. If the dugout is constructed properly and in a suitable location, very little maintenance is required. If algae, vegetation or suspended solids become problems, then control can be either chemical (copper sulphate, diquat, aluminum sulphate, etc.), mechanical (uprooting weeds with chains) or biological (grass carp). Care must be taken in dugouts used for fish culture, as some of the chemical applications are directly toxic to the fish or result in decomposing plants that ultimately deplete the oxygen needed by the fish.

Description

Cysticercosis is an infection caused by the pork tapeworm, Taenia solium. This parasite is found worldwide and is common in countries where raw or undercooked pork is eaten. Although incidences of infection are extremely rare in Canadian and American swine herds, over 1,000 human cases of cysticercosis are reported annually in the United States. Many of these human cases result after travel outside Canada and the United States.

Description

Tall fescue (Festuca arundinacea Schreb.) is used for forage and turf purposes around the world. Native to central Europe, the plant was introduced to the U.S. in the late 1800s and into Canada in the early 1920s from England. Before the early 1980s, tall fescue varieties were developed mainly for forage production, but since that time, more turf-type varieties have been developed for recreational uses.
