The 2017 growing season has been a wet one seemingly across the province, but just how much rain have we received?
Below you can see that since March, we have received more than the average monthly rainfall in nearly all regions of the province. Many regions have received double the monthly average rainfall and this often falls within just a few days.
In most growing areas aside from Eastern and Northern Ontario, the daily maximum is within 0.3°C of the 10 year average. However, the daily minimum temperatures are averaging nearly 1°C warmer than the 10-year average. This is accounting for most of the increase in growing degree day accumulation for this year over the average. We haven’t had many hot days over 30°C, but our overnight temperatures have been a little warmer.
Here’s how different regions across the province compare to their 10-year averages in terms of degree days and rainfall.

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.

Healthy and hardy transplants are a critical part of a successful season. When field planting is delayed by rain, rain, rain, or cold weather and plug transplants must be held, it is important to monitor them closely to maintain plant health and vigour.
Plug transplants can be held in the greenhouse but if already shipped to the field grower, can be stored outside, in an area that receives direct sunlight and is sheltered from the wind. The racks should be elevated to prevent root growth through the bottom of the plugs. If there is a risk of frost, be sure to bring the transplants inside – to a building, a shed, or a greenhouse/hoophouse, if you have one available. Plants should not generally be stored in an enclosed trailer or building for more than 1 or 2 days, as this may result in very soft, elongated plants, especially in crops such as tomatoes.

Despite the abundance of information available on spray drift, we continue to see widespread incidents of damage to a variety of crops every year. Do applicators just not care or are they missing some vital information when making decisions to spray? I believe it is the latter. What is the problem? In my experience, the…

Wind erosion occurs in susceptible areas of Ontario but represents a small percentage of land – mainly sandy and organic or muck soils. Under the right conditions, though, it can cause major losses of soil and property — and can cause off-farm problems, too. Ask your neighbours.
The rate and magnitude of soil erosion by wind is controlled by the following factors: soil erodibility, soil surface roughness, climate, unsheltered distance, and vegetative cover. You know which of these you can control. Continue reading How much soil is lost to wind erosion?
This is a good day to reprint some articles about soil cover. This second one is from Adam Hayes, OMAFRA Soil Management Lead for Field Crops. This was originally run in the CropTalk newsletter in 2013.
Protecting the Soil Over Winter
The fall harvest is all but almost complete. The crop has provided cover for the soil through the summer and early fall. Between now and next spring’s planting when the crop is planted again, the soil will be exposed to pounding rains, overland flow from rain and melting snow, and high winds. All of these can cause significant soil loss and from fields or at the very least strip productive soil from areas within the fields. That soil is lost and the productivity of those areas reduced. A few simple measures can go a long way to protecting your soil.
50% Residue Cover
One of the easiest things to do is to leave at least 50% of the soil surface covered with crop residues in the fall. Continue reading Keeping the soil covered: managing crop residues and cover crops
