It is critical to understand how to stage soybeans for making informed decisions on rolling, weed control, insect monitoring & harvest:
Understanding Relative Maturity
Don't fall into a trap using Heat Units to compare soybean maturity. Understanding how Relative Maturity is used to describe soybeans will make choosing the right variety easier. At this point the best Arms Length Maturity assessment is coming from the '2015 Western Manitoba Soybean Adaptation trial. This helps you to compare the maturity on numerous varieties being marketed in MB. Manitoba Pulse & Soybean Growers | 2015 Variety Evaluation Guide
Iron Deficiency Chlorosis
Are you seeing Yellow patches in your Soybean Field? Could be IDC - here is an explanation:
Using Innoculants Properly
A critical part of soybean production is proper use of inoculants to ensure the soybeans will be able to provide themselves with adequate Nitrogen throughout the season.
Soybean Aphid Threshold:
Like any farm, Sloane AgriVentures Ltd. has been assessing the results with various seed primers, different fertilizer formulations, & foliar feeding. I think there will be a great deal learned in this area in the years to come about timing, formulation, and conditions under which we are likely to see a return. We saw some great results last spring with Precede Soybean. Pictures and link below:

Plant Stand Calculator
Assessing final plant stand is important to fine tune your planting rates and maximizing profit. In the US at this point yield begins to decrease significantly once the final plant stand drops below 120,000. In Manitoba we suspect this number to be 150,000-160,000 but we are still learning. Doing a final plant stand count allows you to better understand your mortality given your present production practices and seeding equipment.
