Why limit seed-placed fertilizer?
May 16, 2018
Generally, small-seeded crops such as canola are more sensitive to seed-placed fertilizer, especially nitrogen and potassium…

Quick test for safe rates of seed-placed fertilizer
May 2, 2018
A quick test for the safety of seed-placed fertilizer is to turn off the fertilizer feed for about 100 feet, mark the spot, and go back and compare stand establishment in treated and untreated areas…

Fertility planning: Safe seed-placed rates
March 2, 2018
What are safe seed row fertilizer rates for phosphorus (P), sulphur (S) and nitrogen (N)? With lower seeding rates than in the past, this concern is greater than ever. Growers need to keep all seed viable to hit plant population targets. Therefore, the best practice is to put up to 20 lb./ac. of phosphate (max 40 lb./ac. of MAP) in…

UCC: 2017 results, 2018 plan
January 17, 2018
UCC field-scale trials in 2016 and 2017 compared the farmer’s base nitrogen rate with a rate 25% higher. With all site years averaged, adding extra nitrogen did provide a statistically significant yield response, but the increased nitrogen did not always provide an economic return when compared to the base rate…

PLAN fertilizer over the winter, don’t APPLY it
November 8, 2017
Winter is a great time to review yield results, fertilizer rates and potential fertilizer shortcomings evident over the growing season. Winter provides the time to look at soil test results from the fall (and even sample fields that weren’t done sooner – albeit with specialized equipment for frozen soil) and make plans to pre-buy and maybe even take delivery of…

Fall soil sampling: The early option
October 4, 2017
Closer to freeze up is best time to capture soil test results that more closely resemble the situation next spring. BUT...sampling soon after combining may satisfy a number of other issues: (1) That is the only time you can get the custom soil-sampler. (2) You want test results in time to make fall fertilizer applications. (3) You want to see…

Timing and depth for fall fertilizer
October 4, 2017
Fall fertilizer is best applied as close to freeze up as possible to balance two objectives: (1) allow soil to seal over the band and (2) reduce losses due to high microbial activity in warm soils…
