In the May edition of the Guelph Service Bulletin, we invite our customers and friends to join us in wishing Papken Bedirian farewell after 30 years at SGS. We will also discuss other current issues, such as UAV's, soil health, storm water testing and nitrogen sampling in corn.

OPEN HOUSE INVITATION - PAPKEN BEDIRIAN RETIREMENT

We are pleased to invite all friends and customers, past and present, to join us on Friday, June 5th, to celebrate and offer well-wishes to Papken Bedirian as he nears retirement.

After Papken's 30 year career at the laboratory, and large contributions to our success, a single day of acknowledgement, reminiscing, and celebrating with cake and refreshments will be a small way of exhibiting our gratitude, and is in no way commensurate with the accolades deserved.

The day will also serve as an opportunity to meet Papken's successor, our Senior Chemist Dr. David Boyle, who was hand-picked by Papken and has been under his tutelage since the beginning of the year.

Please feel free to join us between 11am and 4pm on Friday, June 5th, and be sure to share the invitation with any others who would wish to attend.

While an RSVP is not required, please e-mail Melisa Smith if you have intentions of attending.

UAV PROJECT

Unmanned Aerial Vehicles enable bird’s eye scouting at high resolution with both ‘real’ light and near infra-red imagery. Whether used to diagnose plant stresses, guide field scouts, create sampling zones, influence variable rate prescriptions, or a combination of these, the information can be valuable.

The initial cost, however, can give pause to the decision to purchase a unit outright. With this in mind, SGS Guelph would like to support our dealer network by making the capital investment in UAV’s, and leasing them to interested cooperators at an annual rate.

Please e-mail Dennis if you would like to participate in this opportunity to expand your technological offering to farm clients.

SOIL HEALTH TESTING

While many growers are actively adjusting field management practices to improve overall soil health, it is a long duration before the effects can be seen or are measurable. To provide a benchmark, SGS offers a Soil Health package that includes biological and physical measurements, such as CO2 respiration, potentially mineralizable nitrate, bulk density, porosity, and permeability.

Samples must be collected in an undisturbed core, 6 inches deep. Sampling ‘good’ vs ‘bad’ areas within a field will offer immediate comparison, and geo-referencing the locations will allow for long term before-and-after comparison of the affects of the soil health improvement practices

NITROGEN MANAGEMENT PSNT SAMPLING

Applying a full rate of nitrogen to corn pre-plant allows nature to rob a certain percentage through volatilization and leaching. The losses can be large enough to be economically and environmentally impactful. It is good practice to apply enough N to meet demands of the juvenile crop, then take a 12” (30cm) depth pre-sidedress nitrate sample (PSNT) at 4-5 leaf stage to determine the rate of additional in season nitrogen required.

Where variability exists, due to soil type, organic matter levels, or topography, separate samples may allow for variable rate application. Management zones can be established based on yield maps, grid sampling maps, or bare-ground satellite imagery.

Contact us to book your custom PSNT sampling now to ensure prompt service at side-dress time.

STORM WATER SAMPLES

For greenhouse operations that require storm water testing for the Ministry of Environment (MOE), samples should be submitted directly to our SGS Environmental Services laboratory in Lakefield.

Contact Sarah DeLuca for shipping information.
