Split Application of Phosphorus
Split Application of Phosphorus in the Seed Row & Mid Row Bander® Row
Can phosphorus (P) be put through the Mid Row Bander® fertilizer applicators and expect uptake in canola? The answer is YES.
Drill Spacing
Drill Spacing & Wheat Yields: 10" Edges Out 12"
While the 10" option is still the more popular of the two, if the focus is to increase efficiency, producers may consider moving to a wider spacing to reduce problems in clearing residue as well as reduce horsepower requirements and decrease the number of openers which will reduce maintenance requirements and operating costs. But do these benefits equate to the best investment in the long run? It is important to include the agronomic implications of this decision and its effect on overall profitability.

Targeting Low Canola Seeding Rates
TARGETING Low Canola Seeding Rates
If you are a canola grower, high seed cost is a major input expense for your operation. To control these costs you go to great lengths to set your seeding rate and thoroughly calibrate your seeder to make certain that you do not over apply. You also check over the performance of the drill and monitor your operating speed to ensure seed placement is accurate. Because every dollar of that precious canola seed counts you are focused on doing a great job of seeding it and monitoring the crop’s progress throughout the growing season.

Target Seed Depth
Target Seed Depth for Optimal Emergence
A seed requires moisture in order to germinate. Depositing the seed into sufficient moisture at the time of seeding is the only way to get even emergence in a dry spring.

Bourgault Agronomy Trials - 2018 Results
Canola Large Scale Trials
Three major canola large scale trials were conduction in the 2018 season:
  • Fertilizer Blend Trial Objective – To determine if high yields and greater seeding efficiency could be achieved by applying different placement strategies of single or multiple fertilizer blends in a single pass operation.
  • Starter Phosphorus Trial Objective – Investigate the claim that phosphate fertilizer with a greater content in the orthophosphate form (the plant available form of phosphorus) will be taken up more readily and improve crop performance in the year of application.  This trial was designed to measure the difference of emergence and yield between different types of starter phosphorus fertilizer.
  • Phosphorus – Seed Rate Trial Objective - To see if there was a correlation between the amounts of seed placed phosphorus and seeding rate to emergence and yield.
Wheat Large Scale Trials
  • Increase Protein Objective - To achieve increased protein in wheat by increasing nitrogen rates using either urea or ESN placed in the seed row or in the band, either MRB or SB.
  • Fertilizer Blend Trial Objective – To measure the effects of applying a single blend of fer read more ...
2017 Phosphorus & Canola Trial Update
Fertilizer Placement Comparison Trial - 2017
The purpose of testing various Phosphorus (P) placement strategies is to develop and provide producers with safe options to supply removal rates of P in a one-pass seeding operation.
For the third consecutive year, Bourgault Industries explored different placement options of phosphorus with canola, including extremely high rates seed placed and a split application where starter P is placed with the seed and the bulk of the P fertilizer is placed in the band with nitrogen and sulphur fertilizer.

2016 Bourgault Agronomy Report
Fertilizer Placement Comparison (FPC) Trial - 2016

Phosphorus with Canola
The Bourgault Agronomy team conducted large scale fertility trails for a second consecutive year near St. Brieux Saskatchewan on canola. The goal of the trials is to identify ways to safely increase phosphorus fertilizer rates in a one pass system. This included strategies producers can implement with their current equipment as well as a triple shoot configuration. As like last year, plant access to phosphorus placed in the mid-row bander showed up as an increase in overall yield. There was also a yield response to high amounts of seed placed phosphorus.
Phosphorus with Canola Trial - 2015
Fertilizer Placement Comparison (FPC) Trial

Phosphorus with Canola
The purpose of testing Phosphorus (P) placements is to provide producers with a safe method to apply removal rates of P in a one-pass seeding operation.
The Agronomy team at Bourgault Industries wanted to explore different placement options in canola, including high rates seed placed and a split application where starter P is placed with the seed and the bulk of the P fertilizer is placed in the band with the rest of the fertilizer.
Improve Crop Maturity
Q: Will slow-release nitrogen products make side-band openers safe or increase seed-placed blend safety?
A: The short answer is yes to both products; however, understanding the chemistry of how the products work is critical to determining if these products will fit your cropping program.

Making Higher Yields Happen
by Phil Needham, Needham Ag Technologies, LLC
The world population quietly clicked over the 7 billion mark earlier this year and if forecasts are accurate, it’s expected to increase to around 9 billion by 2050. Feeding and supporting an additional 2 billion people will be a huge undertaking, especially when the world's available farm land is decreasing as a result of expanding cities, roads, and infrastructure. Understanding the agronomy required to maximize yields is critical, not only to ensure profitability, but also to better feed our growing population.

Bourgault Agronomy HandbookBourgault Agronomy Handbook
The purpose of the Bourgault Agronomy Handbook is to focus on the factors involved with the important task of placing the seed in the ground in such a way as to ensure the greatest chances of germination and emergence in the given conditions. It also discusses the importance of fertilizer placement to create the optimum environment for the plant by consistently and accurately placing the seed and each required nutrient in a location that promotes even germination, uniform stand and optimum yield potential.

Preserving Stubble Effectively
Producers in dryer grain-growing regions have long known the benefits of preserving the previous season’s stubble. The preservation of the roots will help anchor the soil to serve as protection from erosion. The standing stubble itself will act as a snow trap, maximizing moisture retention for spring. The stubble will also form a shield from the drying winds and parching sun that robs the soil from existing moisture. The micro-climate which exists within the stubble nurtures the seedling in it’s earliest stages of growth.

Mid Row Nitrogen Banding: Feeding Weeds or Seeds?
As farmers in the upper Great Plains of North America adopt one pass seeding  practices on their farms, placing the majority of the crop’s nitrogen requirements  between every second seed row is a methodology of direct seeding that is growing  in popularity. Recognized early as a low risk method of nitrogen fertilization for direct  seeding, and utilized on many acres since the early 90’s, we now have a large variety  and volume of experiences on how well this seeding practice works. At the same time, there is still much to be learned and understood regarding mid row nitrogen placement as well as other fertilizer nutrients. read more ...
Crop Stressors
Stress is like an iceberg. We can see one-eighth of it above, but what about what’s below? Although small grains are adapted to a wide range of climates and soils, they are sensitive to various agronomic and environmental conditions, including temperature, rainfall, humidity, sunlight, fertility, herbicide carryover, insects, and diseases.

Paradigm Shift
When side-banding was first introduced, nitrogen placed one inch below and to the side of the seed was accepted as the ideal location for adequate fertilizer separation from the seed. Issues including inadequate field finish, seed - fertilizer mix, inconsistent seed depths, caused producers to question the validity of this practice.

Salt Effect
Salt Effect occurs when the concentrated fertilizer is located too close to the seed or seedling, causing desiccation. Placing the nitrogen fertilizer at a safe distance from the seed row will protect the seed from the desiccation effect.
