Work will immediately begin to build irrigation infrastructure for Lake Diefenbaker for up to 500,000 acres of land, the Saskatchewan government announced in a news release on July 2. The project will more than double Saskatchewan’s irrigable land. It will begin with an immediate $22.5 million investment in preliminary engineering and initial construction, with continued to project construction expected to occur approximately over the next 10 years in three main phases at…
As heat and drought continue across the province, irrigation has been the order of the day. Many fields are in the tuber setting stage, a stage that requires adequate soil moisture for an optimum tuber set. Fields with closed rows and vigorous canopies keep the soil cool, which reduces stress. Potatoes suffer when soils get hot in direct sun. Many fields still have open canopies, the result of late planting. Unfortunately, a…
For a century at least, potatoes have been one of our province’s staple crops. More recently, they’ve become a pillar of southern Alberta’s economy. And now university-based researchers are on hand for support, as producers prepare to grow the industry still further. With a major potato processing plant now under construction in Lethbridge, industry officials predict a jump of nearly 10,000 more acres put into potato crop rotation. On Friday, scientists at…
Irrigation management is about deciding when to irrigate and how much water to apply. When irrigations are managed properly, sufficient water is available for plant uptake for photosynthesis and transpiration during the growing season and excess water loss – through deep percolation and surface runoff – is minimized. Numerous studies have quantified the magnitude of yield reduction when irrigation is delayed and available soil water within the root zone of the crop…
Agricultural producers could, in the future, make use of better forecasts to more efficiently irrigate their fields using a Purdue-developed technology that could more accurately sense soil moisture below the surface through measuring the reflections of communication satellite signals. “The reflectivity of the surface is a function of the soil moisture, and that allows us to quantify the amount of moisture in the soil so, if necessary, growers can take corrective actions…
Potato producers know all too well that controlling Mother Nature is as likely as reigning in a two year-old. In either case, you’re doomed before you start. At the same time, there are ways to optimize water use efficiency and minimize the damage from floods and droughts. For this edition of Roundtable, Spud Smart assembled five industry experts to discuss the importance of water management to potato production, and how to deal…
Precision agriculture is cutting edge, high-tech and full of potential. At least some western Canadian potato farmers, however, see it as overwhelming, costly, frustrating, and/or difficult to implement. If you look past the hype and excitement surrounding precision agriculture, you’ll find a group of farmers who have tried it and quit, or who were turned off the concept before they ever started. Jeff Bronsch, an agronomic consultant in Taber, Alta., understands farmers…
In recent years, the concept known as variable rate irrigation or VRI has become a catchphrase among irrigation specialists and growers alike. Some would even describe it as precision agriculture applied to irrigation. In essence, VRI is the process of applying differing irrigation amounts to match crop water demands at a small scale within a particular field. Most irrigation equipment manufacturers in Canada nowadays offer systems that are or can be retrofitted…
