Do you have a water contingency plan?

Jennifer Jarvis, OMAFRA

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.

Temporary water permits available for Ontario irrigators

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.”

Irrigation system assessments

Are you concerned that your irrigation system is not applying enough water? too much water? or applying unevenly? To request an Irrigation System Assessment contact Rebecca Shortt, OMAFRA Water Quantity Engineer at 519-426-4920 (limited availability).

Australian research has shown that one of the greatest opportunities for irrigation water savings are in improving how evenly the water is spread across the field by the irrigation system. Continue reading Irrigation system assessments

How long do I run my drip lines?

Rebecca Shortt, Engineer – Water Quantity, OMAFRA – Simcoe

Irrigated tomato fieldThis blog post will show the 2 steps to roughly calculate how long to run a drip system.

First calculate the plant water demand. This was shown in my post from last week.

Plant Water Demand (U.S. gal)
= ET (mm) x Kc x Area occupied by plant (ft2) x conversion factor 0.0245 Continue reading How long do I run my drip lines?

Irrigation update

Rebecca Shortt, Engineer – Water Quantity, OMAFRA – Simcoe

Drip irrigation of tomatoThe month of May and the first 2 weeks of June have been extremely dry (<40% of avg rainfall). The areas of Niagara and Peterborough are of particular concern because of lengthy dry conditions through the entire spring (since March 1st) and stretching back through 2015.

This is a critical period for most horticultural crops where the fruit or flesh development is occurring as well as rapid vegetative growth.

I know I need to irrigate; how much do I apply? Continue reading Irrigation update
