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.

Subsurface Drip Irrigation for Field Crops Tour

From https://farmsmartconference.com/, this is targetted at field crop producers, but may be of interest to vegetable producers interested in subsurface drip irrigation.

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

Is the Nitrogen Still There?

Anne Verhallen, OMAFRA Soil Management Specialist – Horticulture

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.

Southwest Crop Diagnostic Days 2015

The program is out for Southwest Crop Diagnostic Days 2015, July 8-9 at Ridgetown Campus.

  • Hitting the Goldilocks Spot – Managing residue and building soil structure for better crop establishment.
  • Roots and Shoots – Digging deeper into cover crops.
  • Weed-posium Workshop – Problematic Pigweeds, a small group that presents some big challenges.
  • Narrowing the Yield Gap of 30” Soybean Rows – Wide rows are becoming more popular and have a number of advantages. Do inputs such as banded fertilizers, foliar fungicides, and foliar fertilizers work ? This stop will also address how light interception impacts yield.
  • Timing Matters – Determining cereal stages for application of growth regulators, fungicides and nitrogen.
  • Herbicide Injury in Corn – Learn to recognize the symptoms caused by new and common products.
  • Herbicide Injury in Soybeans – A hands-on look at herbicide injury in soybeans.
  • Feeling the Pressure – How nozzle pressure affects spray quality and coverage. A demonstration of the negative impacts of using spray nozzles outside their ideal pressure range…. and it happens all the time.
  • Water Use Efficiency – Is water the next limiting factor in crop production?
  • Disease Management and ID – IDing common diseases and management options such as fungicides for soybeans and corn.
  • Carbon Copy Corn Plants – Quantifying plant stand variability and its impact on corn yield potential

Processing tomato production – short survey

For processing tomato producers interested in helping out a grad student with an interest in the tomato industry (something that should be encouraged, I think), see below. Whether you irrigate or not, it would be very helpful to her if you would take a few minutes to fill out her survey.

Hello!
I’m Ana, a grad student researching the effects of different water management practices & technologies on/off-farm.

I’m interested in gathering your opinions on irrigation in tomato growing. For this I put together several questions that should take about 10-15 min to complete. Your answers are crucial for my research and would be greatly appreciated. Please follow this
