Life cycle of weeds

Weed identification is halfway to control.

Identifying your weeds and understanding the life cycle of weeds is an important step to a proper and sound weed management strategy for your farm.

Each weed has a certain life cycle attached to it. It is important to know the life cycle of weeds to help you quickly identify which weed it could be in the field and to know how to control it. Read more

Prevent farm fires

Did you know?

Faulty electrical systems cause approximately 40 per cent of farm building fires with a determined cause, making it one of the leading known causes of farm fires.

What can you do?

Regular inspections and maintenance are key to reducing the risk of a fire. We recommend that you work with a professional to inspect and monitor your farm buildings. Read more

Critical weed-free period

Weed-free period in corn In corn this period occurs from V1 to V6 (1 to 6 leaf collars). Some sources will mention that it even begins at the VE stage (emergence). During this time the corn crop needs to stay clean. Weeds will affect yield

Day-to-day work around the farm doesn’t have to be painful

Here are some tips to avoid injury by evaluating activities and preparing for them

Farmers take their aches and pains as part of their work, but it doesn’t have to be that way.

Understanding factors that contribute to on-farm injury can be a start to reducing risk of getting hurt.

Why it matters: Farmers are busy, especially in certain seasons of the year, so reducing risk of injury when they need to be at their physical best can have important farm business implications.

Julie Anceriz, Syngenta Canada’s territory health and safety manager, told a recent Whole Farm Health seminar put on by the Ag Women’s Network, that there are ergonomic factors that affect risk of injury no matter what type of work one does, whether sedentary at an office chair or in a combine or tractor, or active, lifting and doing heavy work.

Early season pests

With the cold winter that we have had, a slow start of insect development may occur. Many of the acres planted in Ontario have been planted with neonicotinoid insecticides. With the current debates over neonicotinoid insecticides, the best strategies to control pests is to start with a good knowledge of crop pests. By understanding early […]

Corn Nitrogen Response Curve

Nitrogen stabilizers

Nitrogen management has always been a challenge in high nitrogen demand crops such as corn and winter wheat.

The three pathways that can contribute to significant nitrogen loss are:

  • Volatilization (loss of ammonia nitrogen to the atmosphere from the soil surface),
  • Denitrification (which occurs when soils are saturated and in an anaerobic environment) and
  • Leaching (downward movement of nitrate nitrogen out of the rooting zone due to excessive rains)

The challenge has always been to make nitrogen available when the crop needs it and minimize the exposure of nitrogen to the weather scenarios that contribute to N loss. Consider the nitrogen response relationship for corn and winter wheat (below):

Corn Nitrogen Response Curve

We often apply nitrogen early in the season before the crop actually utilizes it. For example, the demand for nitrogen in corn is at its peak at about the V10 growth stage (often around early to mid-July). Split-applying nitrogen has been a reasonably effective way to reduce the risk of nitrogen loss, however, with added application costs. Read more

Do you understand the different forms of micronutrients?

Increased interest in micronutrients

When it comes to applying micronutrients, understanding the different forms that they can come in is very important to know. There is an increased interest in micronutrients with today’s growers. Many growers and advisors realize that these can be a major limiting factor in crop growth. In order to increase yields, the levels in the soil of micronutrients need to be monitored and properly placed. As well, more accurate soil testing through zone management has created the need to address micronutrients even more. There are agronomic advantages and disadvantages of each of the following forms of micronutrients. By understanding the different types of micronutrients, you can cater the right micronutrient product to the right field and operation. Read more
