In 2016, many areas of the province saw very warm and dry conditions, creating challenges for horticulture and field crop producers. Many wells were still dry leading into the winter. In other years, like the start of the 2017 growing season, the province experienced periods of excessive rain, leading to saturated soils and flooding.
No one can control the weather, but we can plan for it. The Ministry of Agriculture, Food and Rural Affairs (OMAFRA) encourages you to plan for future weather – conserving water and using it efficiently can help during low water conditions, and having effective drainage systems in place can help with saturated soils and runoff.

The Grower is reporting that due to the extremely dry growing season, the MOECC, supported by OMAFRA, has agreed to a streamlined approval process for Permits to Take Water (PTTW).
“The streamlining of the approvals process will be done during the current growing season and on a temporary and short-term basis. Requests by growers will be dealt with on a case-by-case basis and may include takings from the Great Lakes and connecting channels, takings from dugout ponds and takings from neighbouring permitted sources such as ponds.”

After heavy rains and wet soil conditions, questions come up about nitrogen. Is it still there? Should I add more?
Here comes the stock answer – It depends… Yes that seems to be a cop out but for good reason. There are a number of factors that come in to play here. Let’s take a closer look and then make some estimates.
The amount of nitrogen lost depends upon the amount that was in the nitrate form. Ammonium is held by the cation exchange complex and not lost. The conversion of ammonium to nitrate (a microbial process) is interrupted when the soil is saturated. Nitrate however can be lost through leaching and denitrification.

Excerpts taken from ONvegetables in the Grower, April 2014. A full pdf version of this article is available at 2014_Infosheet_Phytophthora-in-irrigation-water
Phytophthora blight (Phytophthora capsici) is a serious and complicated disease of peppers and cucurbit crops. Under the appropriate environmental conditions, infections can quickly spread and completely destroy a crop in a matter of days.
Dr. Mary Hausbeck, Michigan State University, conducted an extensive study on the presence and potential impact of phytophthora in irrigation water sources. The study did indicate that irrigation from surface water is a potential source of phytophthora infection in cucurbit and pepper crops.

The US EPA is offering a webinar called Improve Water Quality by Using Cover Crops and Other Conservation Practices – March 25 from 1-3 pm EST. It features Dan Towery and Dr.Han Kok. Dan has been speaking in various spots in Ontario this past winter – he has a lot of good cover crop information to share. Hans is with the Indiana Conservation Cropping Systems Initiative and has good farm-developed information to present. To register (free) go to: http://water.epa.gov/learn/training/wacademy/webcasts_index.cfm.
The US National Institute of Food and Agriculture’s Specialty Crop Research Initiative have been holding a 14-session webinar series on plant pathogens and irrigation water.
They started on October 8, 2013, but you can watch recorded versions of the webinars that you’ve missed. You can also find transcripts of the webinars and in some cases, additional resource materials. Continue reading Irrigation water quality and plant disease webinars
