Irrigation
The goal of irrigation scheduling is to ensure the crop is never under water-induced stress that would limit yield potential. It involves determining the correct amount of irrigation water to apply to a crop at the right times to achieve optimum yield.
Pivot irrigation is by far the most common method of irrigating crops in Western Canada. Over 80 per cent of the 1.7 million acres of Alberta’s irrigated land uses pivot systems. Low pressure pivots with drop tubes and spray nozzles have become the most common form of pivot irrigation due…
Researchers at the University of Guelph are finding that Ontario crops can benefit from subsurface drip irrigation. The technology (which is relatively new to the province) is a low-pressure, high-efficiency system that uses buried polyethylene drip lines to meet crop water needs by applying water below the soil surface using…
Conservation management practices can increase sugar beet yields over time – that’s one of the key messages from a 12-year irrigated cropping study that compared conservation and conventional management.
Soybean production is spreading across the Prairies. In 2016, Manitoba had nearly 1.64 million acres seeded to the crop, and Saskatchewan seeded 240,000 acres. In Alberta, production is still relatively low at around 15,000 acres, according to industry estimates. But with early and very early maturing varieties becoming more common…
Variable rate irrigation (VRI) is a great idea, but many practical questions remain. Researchers are working to answer these questions so Prairie irrigation farmers and agricultural service providers will be able to more easily and effectively adopt VRI.
Droughts are a part of the Prairie climate and severe, prolonged droughts can put a strain on irrigation water supplies. Improvements can increase energy-use efficiencies, improve crop yields, and enhance the sustainability of water resources. Some of these improvements are also  eligible for current financial incentive programs.
It’s official: 2016 was the warmest year on record. The United States National Oceanic and Atmospheric Administration (NOAA) reports the average global surface temperature reached 14.83 C – the warmest it’s been since modern temperature records began in 1880.
A collaborative effort between Potato Growers of Alberta and the Oldman Watershed Council has produced three videos on watershed management and health. Click here to view the first of the three videos, highlighting the production history of the area.
Fertigation is quite common in southern Alberta, but very, very little research has been done on it in replicated plots,” says Doon Pauly, an agronomy research scientist with Alberta Agriculture and Forestry. His recently completed study took up the challenge of assessing the effectiveness of fertigation in wheat and canola.
So far, Alberta remains free of invasive mussels. Originally from Europe, zebra mussels and quagga mussels arrived in the Great Lakes in the 1980s. Since then, these two species have been spreading through North America’s waterways, clogging water-related infrastructure, damaging aquatic ecosystems and degrading recreational areas. In 2013, the mussels…
Lodging can be a serious problem, especially in irrigated crops. Of course, variety selection and nutrient management are important tools for managing lodging. But producers may want to grow a crop variety with not-so-good standability because it has other important traits, and they may want to use higher nitrogen rates…
To replant, or not to replant is often the question when a sugar beet stand has been severely damaged. Ultimately, a grower has to do one or the other, and making the right choice will increase net returns from the crop. A six-year study has evaluated replanting recommendations for southern…
Variable rate irrigation is a challenging new topic for both producers and researchers, so we’re excited to be working on it and seeing what we can learn and share with producers,” says Alison Nelson, an agronomist with Agriculture and Agri-Food Canada (AAFC) in Manitoba. She is leading a three-year project,…
Saskatchewan’s growing conditions aren’t exactly ideal for corn, a crop that loves heat and water. But with the development of shorter-season hybrids, an increasing number of Saskatchewan growers are trying corn for silage, grazing or even grain. Irrigation can play a key part in making corn production more successful.
