How to Obtain GOOD DATA from Strip Trials…..Use a Calibrated Yield Monitor…

In 2016, some of  John Heard’s corn nitrogen plots yielded over 200 bu/ac with the University of Manitoba plot combine.  He refused to report such astounding yields until the electronic weighing system had been verified with bagged and weighed yields.  Likewise scrutiny and calibration is required when using yield monitors for strip trial tests.  In 2016 Manitoba […]

How Can I Reduce Fertilizer Losses in Dry Spring Soils?

Dry spring weather is great for seeding but may play havoc with some fertilizer applications and losses. 1.Seedplaced fertilizer – Where seedbed moisture is low or when weather is hot and windy, reduce the rates of seedplaced nitrogen  by approximately 50 per cent. Table 7 of the Manitoba Soil Fertility Guide  http://www.gov.mb.ca/agriculture/crops/soil-fertility/soil-fertility-guide/nitrogen.html indicates safe rates […]

Are Herbicides Still Effective After a Fall Frost?

Fall is a great time to control perennials such as Canada thistle, perennial sow thistle and dandelion.
