7.    Measurement of carbon budgets for some Manitoba cropping systems.
Author: Amanda M. Taylor, Dept. of Soil Science, University of Manitoba, Winnipeg, MB R3T 2N2
Poster Summary: Carbon dioxide flux measurements taken over a 30-month period are combined with manure additions and harvest removals to assess the carbon budget of three fields.

Authors: Laryssa Grenkow, Don Flaten, Department of Soil Science, University of Manitoba, Winnipeg, MB R3T 2N2, Cynthia Grant, Brandon Research Centre, Agriculture and Agri-Food Canada, Brandon, MB R7A 5Y3, and John Heard, Manitoba Agriculture, Food and Rural Initiatives, Carman, MB R0G 0J0
Poster Summary: Canola plant stands were evaluated in the field and under a controlled environment to determine the toxicity of seed-placed phosphorus and sulphur fertilizer blends in Canadian soils.

9.    2012 Manitoba Fall Soil Moisture Survey
Author: Marla Riekman
Poster Summary:  Soil moisture samples were taken just prior to freeze up, to a depth of 4 feet.  Samples were taken from 105 locations across the province, representing all regions of agro-Manitoba.  A map of fall soil moisture status has been created and will be showcased in the poster. Data from this soil moisture survey can be used as a general information/planning tool for producers and agronomists and will also be used for flood prediction modelling in 2013.

10.    Buckwheat, a unique crop.
Author: Rejean Picard
Poster Summary:  Buckwheat is a broadleaf plant is grown in many parts of the world. Early settlers from Ukraine brought buckwheat to Manitoba where it was cultivated and used in traditional dishes. Buckwheat has many well documented nutraceutical properties as a food ingredient.

11.    Nutrient Cycling in winter grazing cattle on pasture; five years following bale grazing once.
Author: Rejean Picard
Poster Summary:  Bale grazing cattle on pasture during the winter season is growing in popularity among cattle producers in Manitoba. Bale grazing adds important amounts of nutrients to the site. Nutrient levels rapidly increase in the soil and impact plant growth, feed quality and soil fertility levels for many years after bale grazing even only once.

12.      Rescue applications of nitrogen for non-nodulated soybeans.
Authors: John Heard1, Dennis Lange2 and Joe Peters3.
Poster Summary:  Failure of soybeans to nodulate can lead to severe yield reductions. This study considered different yield rescuing applications of nitrogen so to retain as much yield as possible. The application of 100 lb N/ac following emergence actually increased the severity of iron deficiency chlorosis (IDC) in the crop and did not affect yield. The 50 and 100 lb N/ac treatments at flowering did not influence yield, whereas applications during pod filling increased yields 24-32%, respectively. Despite the complete absence of nodules, the check yield was still 33 bu/ac, crop yellowing was not severe and tissue nitrogen levels remained sufficient. Obviously the nitrogen contribution from the soil was considerable; consisting of soil test = 56 lb nitrate-N/ac and mineralization from the 4.3% soil organic matter.

14.     State and Provincial Soils: Pick Yours Out of this Line-up?
Author:  John Heard
Poster Summary:  Each state and most provinces have designated a “sate or provincial soil” that is representative with unique and/or important attributes. Between 2011-12, some 24 such soils have been captured, photographed and released unharmed. This poster encourages examination of visible traits of the soil profile with accompanying characteristics on their climatic adaption (average temperature and annual precipitation), natural vegetation and type of deposition. Armed with this information the viewer can complete a quiz to match the soils with their home state/province. The characteristics have large implications for nutrient management, such as soil nitrate testing, fall nitrogen application, broadcast vs band application of phosphorus, use of cover crops, nitrogen mineralization.

15.    MAFRI Crop Diagnostic Centre: Services and 2012 Highlights
Authors:  Holly Derksen1 and Mardi Desjardins2. 1Crops Knowledge Centre, Manitoba Agriculture, Food and Rural Initiatives, Carman, MB R0G 0J0, 2Crops Knowledge Centre, Agricultural Services Complex, Manitoba, Agriculture, Food and Rural Initiatives, Winnipeg, MB R3T 5S6
Poster Summary:  The Manitoba Agriculture, Food and Rural Initiatives (MAFRI) Crop Diagnostic Centre processed approximately 1270 samples in 2012. The majority of these samples were submitted for disease diagnosis, but they also included environmental injury, herbicide injury, insect and weed samples submitted for identification. Highlights from this season included a number of small grain samples diagnosed with symptoms caused by adverse environmental conditions (heat/drought stress) and a variety of crops submitted showing aster yellows symptoms. Other disease highlights include root rots, especially in cereal crops and soybeans, and blackleg in canola. The Crop Diagnostic Centre is a valuable tool for growers and agronomists across the province. All agricultural samples are processed free of charge, but accurate diagnosis depends on the receipt of fresh, whole samples accompanied by detailed completed forms. Forms and instructions for submitting samples to the Crop Diagnostic Centre can be found at http://www.gov.mb.ca/agriculture/crops/diseases/pdf/fac63s00formpdf.pdf.

16.    Impact Foliar Fertilization of Canola with a Nitrogen-Zinc Product
Authors:  R. E. Karamanos, N. A. Flore, J. T. Harapiak†, Viterra Inc., 10517 Barlow Trail SE, Calgary, AB, Canada T2C 4M5 (e-mail: rigas.karamanos@viterra.com ); †deceased.
Poster Summary:  This study is a record of 40 experiments from the Westco annals that were carried out over a period of six years (1989-94) and involved application of a foliar product (NZn) on canola. The experiment at each experimental site was set as a split-plot design with and without application of NZn as the main plot and a variety of other treatments as sub-plots. In total, thirteen different experimental designs were employed involving rates and method of application of nitrogen (N), phosphorus (P) and potassium (K) or their combination. Soil samples were taken from 0 to 15 and 15 to 30 and 30 to 60 cm depths of all plots. Foliar application of NZn was employed at the flowering stage. Numerically, a response to the foliar application was obtained in 85% of the time; however, statistically this occurred only in 60% of the cases. Statistically significant yield increases varied between 84 and 672 kg ha-1. These findings suggest that follow up tests with current canola cultivars should be conducted to ascertain the benefit of such a product in current agriculture.
