This is National Soil Conservation Week. It runs from April 21st to 27th. Soil conservation for many years focused on protecting the soil from wind and water erosion. Today the soil is becoming an integral part of the larger environmental picture. Soil conservation is now directly linked with water ... Continue reading
The fertilizer value of liquid hog manure is significant and can provide all the required P205 and K20 and most of the nitrogen required by a corn crop. The table below shows the average available nutrients on a per thousand imperial gallons per acre basis. The availability is based on spring ... Continue reading
Glyphosate resistance: hot button issue over the winter has been glyphosate resistant weeds, particularly Canada fleabane.
Awareness is good at retail, but not at farm gate, where it varies from excellent to “what does fleabane look like?”.
From Essex to Niagara, assume that... Continue reading
Dr. John Lauzon, University of Guelph (adapted from a presentation given at the workshop – Making Sen$e with Cover Crops Feb. 28, 2013)
Cover crops may be grown for many reasons including; reducing erosion, adding soil organic matter, soil structural improvement, nematode suppression, weed su... Continue reading
Leaving a minimum of 30% crop residue has been proven to minimize top soil losses from wind and water erosion. But what does 30% soil cover look like? Do certain tillage implements leave less than 30% crop residue? Crop residue in the form of corn stalks or cereal straw, or green cover (growing crop... Continue reading
If you are planning to retire your red clover cover crop by the end of September you may be shorting the corn crop of some residual nitrogen. In the presentation below Peter Johnson summarizes some new research out of the University of Guelph by Dr. Steve Bowley. Control options for red clover are a... Continue reading
Application of manure from animals infected with pathogens is a potential method for spreading infection. This becomes a higher risk when the manure is applied to crops used for animal consumption.
Johne’s (yo-nees) Disease is a persistent and debilitating bacterial disease that affects the i... Continue reading

Monday April 23, 2012 was a reminder that wind erosion can be a serious issue in Ontario (photo 1). Soils are most vulnerable to wind erosion when they are bare or when crops are newly emerged.
Photo 1: Wind erosion south of Ridgetow... Continue reading
Ensure at least 2 modes of action are used in all herbicide applications as part of the resistance management strategy. Where weed escapes from burndown treatments require additional glyphosphate, we need to send the message of combined modes of action as good weed management ste... Continue reading
GENERAL: The relatively mild winter and early start to the spring season means that there will be a re-evaluation of many “normal” practices. Early break of dormancy for forage, wheat and tree crops, opportunity for early application (or split application) of nitrogen to wheat crops, germinati... Continue reading
A livestock farmer appreciates the value that manure has to their cropping system. In the past, cash crop producers, who did not have access to such a beneficial organic soil amendment were envious. Now there are options to source and apply various different organic amendments, but with many non... Continue reading
Environmental Commissioner Concerned About Soil Erosion Risk
The Ontario Environmental Commissioner 2008/2009 Annual Report identified the risk of soil loss from water erosion as an environmental concern. Referencing Agriculture & Agri-Food Canada 2001 environmental indicators for Ontario cropl... Continue reading
There is lots of talk these days about crop residue removal for bioenergy purposes. We have gone through the first wave of trying to make it very clear to those less familiar with agriculture that this crop residue has real value.
Crop Residue Value Components
Crop residue value hinges on a few co... Continue reading
