Congratulations to all farmers

Over the past number of years Ontario farmers have reduced the use of pesticides and greatly reduced the environmental impact of them. At NK we are proud of your accomplishments and support your continued effort to protect the environment. Please read the attached article by Lilian Schaer printed in the Guelph Mercury.
Farmers take safe pesticide application seriously


Thin soybeans – Eastern Ontario update

Submitted by Clare Kinlin, Sales and Agronomy manager, Eastern Ontario

The planting conditions for soybeans were generally ideal early in the spring but in Eastern Ontario drier weather and variable field conditions have created dry seed beds in some areas of the field. The best method for evaluating your stand is with a Hula Hoop. I like this method best as it is easy and quick to do. Randomly through a hoop (take 2 it is quicker) into your stand and count the emerged plants in the hoop. The size of the hoop will determine the population of the stand. There are several charts available to determine the actual population. Soybeans unlike corn we generally do not do a total replant but rather “thicken the stand”. I personally like using a corn planter to do this as does less damage to the existing stand.

Purple corn – Eastern Ontario update

Submitted by Clare Kinlin, Sales and Agronomy Manager, Eastern Ontario
Every year we see purple corn and think that it is phosphorus deficiency in the plant, which it could be but most likely is poor root development of the young plant. This poor root development can be caused by many things such as soil compaction, sidewall compaction, soil type, soil moisture (too much or this year too little), planting depth, nutrient availability, herbicide carry-over, etc. There is always one thing that is common with purple corn and that is poor root development. The vegetative part of the plant is producing more sugar that what the used by the plant causing the tissue to turn purple from the sun. These symptoms are usually short lived and the plant quickly grows out of it. Get your shovel and see what is affecting your corn plant’s roots. In the picture see the two different root masses from the same field.

Looking for pests

Do you have a corn field that is being attacked by black cutworm? Maybe you have a corn field that is getting munched on by fall armyworm or western bean cutworm. The multipest complex is attacking corn fields in Ontario and Quebec. What is the multipest complex? Black cutworm, western bean cutworm, fall armyworm and corn earworm are the major corn pests in this complex that maybe attacking your corn.

Do you have something eating your corn? If so please contact your local NK rep or add a comment here. We want to see your fields.

Magnesium Deficiency Showing up in Corn

On many sand fields in West Elgin or East Kent, sharp magnesium deficiencies have shown up in 3-4 leaf corn. Yellow interveinal striping can be quite pronounced. Areas with high calcium numbers and lower organic matter seem to be the worst. Sandy fields with with preplant nitrogen also seem to be showing sharper symptoms. The good news is that the corn will grow out of the symptoms as roots penetrate deeper in the soil and gain access to more magnesium. By the 5-7 leaf stage, the symptoms should be gone.
