Week #1: Feb 4th – 1:30 pm (EST)

pH, CEC, Optimum Nutrient Levels by Soil Type and Variable Rate Applications | Register on Zoom

How much do you really know about soil pH and CEC? These two soil parameters can have a huge impact on the availability of many of your macro, secondary and micronutrients.

A&L has completed years or research to demonstrate how CEC and pH levels should be used to determine the nutrient availability within a soil profile. Hear about the different methods for testing of pH and CEC and some of their short comings.

Learn how we are often managing pH and CEC as opposed to 'fixing' them within our fields…CEC is really a measurement of the soils ability to hold and release nutrients, so when we try to determine the amount of nutrients to include in a variable rate application recommendation, it is imperative we first understand how available and tightly bound those nutrients are within the soil.

Week #2: Feb 11th – 1:30 pm (EST)

Phosphorous and %P Interpretation | Register on Zoom

Phosphorous…the salt of life and the plant's main energy source. In plants, it is involved in: root development, cell formation, crop maturity and seed development, so it is critically needed throughout the entire life cycle.

Phosphorous, although rather immobile in the soil, has received a lot of media attention lately due to its contribution to algae outbreaks within the great lakes. More and more pressure is being put on producers to properly manage their phosphorous soil levels and application methods to try and mitigate off farm losses; however, cutting back rates of phosphorous or mining it from existing soil levels can have devastating impacts on yield and quality.

This will be a technical session strictly focused on phosphorous, with discussions on topics like its role in the plant, various testing methods, and determining how much P is available to the plant based on base saturation levels and/or soil types.

Week #3: Feb 18th – 1:30 pm (EST)

Potassium and K/Mg Ratio | Register on Zoom

The big brother of the cations, potassium is one of the essentials that is directly tied to over 60 enzyme systems in plants and it is one of the nutrients most used by the plant (hence it is called a macronutrient).

K is the fuel for photosynthesis and is critical to many plant processes including the ATP production pathway. Low K levels are also known to attract leaf sucking insects. Cations should be rated on their optimum level for their soil type (called base saturation) and the ratios of cations like K to Mg (and Ca to Mg) can have a very significant impacts on the availability of other nutrients within the soil.

Improper K:Mg ratios can also have a significant impact on quality and diseases severity. This session will do a deep dive into the role of potassium in your soils.

Week #4: Feb 25th – 1:30 pm (EST)

BORON | Register on Zoom

Boron, perhaps the least understood of all micronutrients! In this session we will spend 1.5 hours doing a deep dive on the importance of Boron to your cropping practices and what are the optimum levels in soils for plant availability.

Topics will include its essential role in the plant for processes such as: sugar transportation; cell wall synthesis; lignification; cell wall structure; carbohydrate metabolism; respiration; root growth and pollination to name a few.

The session will also cover boron deficiency symptoms and identification and what are the optimum plant tissue levels for quality and yield. We will cover mobility and uptake mechanisms; how boron availability can be dramatically impacted by CEC and pH; how K availability is impacted by boron; how best to apply/incorporate boron into your nutrition program, and the role of boron in soil health.

Week #5: March 4th – 1:30pm (EST)

Sulfur and the Micronutrients | Register on Zoom

In this session we will discuss sulfur needs by crops and soil release of sulfur plus a discussion on Micronutrients. Although they are called "Micro" nutrients, a deficiency in a micronutrient can have a MACRO impact on yield! For many years, micronutrients have often been left out of fertilizer blends and farmers relied on existing soil levels to meet the plant's needs.

With an increased focus on essential secondary and micronutrients like sulfur, zinc, boron and magnesium (to name a few) and new fertilizer coating technologies that allow micronutrients to be impregnated onto fertilizers, more and more growers and retails are including these products in modern fertilizer blends…that’s a great thing as these nutrients are critical to fuel our new high yielding racehorse hybrids.

This 1.5-hour session will do a thorough review of numerous different micronutrients, including nutrient sources and availability, complex nutrient interactions & tie-ups, micronutrients and their relation to critical crop stages as well as their impact on disease and quality.

Week #6: March 11th – 1:30pm (EST)

Soil Health and Seed Endophytes | Register on Zoom

The topic of soil health has had a lot of buzz recently. During this 1.5-hour session, hear about the numerous research findings that A&L has led, including developing new methods and tests to quantify soil health.

Soil Health is a function of the chemical, physical and biological characteristics of a soil and many complex interactions between soil chemistry and microbiological have now been directly correlated. Find out how some of the key functions of a healthy soil impact topics such as: acting as a reserve for microbial biomass and nutrients; numerous microbial activities that can aid in the fixation of nutrients; disease suppression; production of biostimulants; and buffering environmental stresses.

Soil health management practices will also be discussed. A second topic of this session will focus on seed quality: watchouts and must know information for when you are growing your own seed and the impact subpar seed quality can have on yield.

Week #7: March 18th – 1:30pm (EST)

Plant Tissue Nutrient Analysis and Interpretation | Register on Zoom

Many producers are starting to incorporate plant tissue testing and Plant Monitoring Program "PMP" into their crop production practices. Tissue testing is a great way to demonstrate how nutrient release from the soil is occurring through the growing season. It is also a valuable tool to help identify potential deficiency areas in fields before they can be visually seen.

This allows growers to apply "timely" applications of foliar nutrient products to save yields and improve quality prior to the deficiency taking hold, or to adjust their fertilizer plan for the following season. Reading a tissue report is much different that reading a soil report and understanding the local soil conditions as well as the crop physiological stages from when the sample was taken is imperative to gain value from a tissue test.

By geo-referencing both your soil and tissue sample locations, growers can also "track" over time how their fertilizer and application practices impact nutrient availability in the plant. Best practices for tissue sampling, collection and interpretation will all be reviewed in detail during this 1.5-hour session.

A&L Canada Laboratories has been on a mission is to help growers and their trusted advisors understand soil and the role it plays in crop production and by connecting trusted research to the adoption of best practices. Greg Patterson, CCA, has been delivering Soil Fertility Workshops for the past 30 years to thousands of participants across Canada.
