What Millions of Soil Tests Reveal About Soil Fertility

What Millions of Soil Tests Reveal About Soil Fertility

November 3, 2026 30:39
Episode notes
Are soils supplying the nutrients crops need? Millions of soil tests from across the U.S. and Canada offer a revealing picture.
 
In this episode, Dr. Karl Wyant is joined by Dr. Leanna Nigon, director of agronomy and research at The Fertilizer Institute (TFI), to explore findings from the latest TFI Soil Test Summary, drawing on approximately 10.2 million soil samples from across the U.S. and Canada. With more than 40 percent of samples testing below critical levels for phosphorus and potassium, Leanna explains what those thresholds mean for fertilizer decisions and how nutrient needs vary across regions.
 
They also explore soil pH and soil organic matter levels, why regional averages only tell part of the story and how consistently testing your own fields can help you track changes and plan ahead.

Which Potash Fertilizer Fits Your Fields?

October 6, 2026 36:56
Episode notes
What should you consider when choosing a potassium source?
 
In this episode, host Dr. Alan Blaylock is joined by David Holden, owner of Holden Research and Consulting, to explore how crop needs, soil properties, water source and the nutrients supplied alongside potassium can affect how well a particular source fits into a system. They compare potassium chloride (MOP) and potassium sulfate (SOP), discuss why chloride can create challenges for certain crops and explain what growers should think about when evaluating each source.
 
They also explore how potassium rate, timing and placement can align with crop demand, why potassium availability matters as crops develop and how irrigation can influence the source you select. The conversation offers practical considerations for selecting and evaluating potassium sources, including potassium chloride, potassium sulfate, potassium thiosulfate and potassium nitrate.

Understanding the Soil Factors Limiting Yield

Understanding the Soil Factors Limiting Yield

September 29, 2026 32:04
Episode notes
Soil fertility isn't always the yield-limiting factor. Compaction, salinity, soil acidity and water management can all affect how well crops grow and how effectively they access nutrients.
 
In this episode, Lyle Cowell is joined by Marla Riekman, Soil Fertility Specialist with Manitoba Agriculture, to explore some of the other factors that can hold back crop performance and productivity. They discuss how salinity and compaction are connected to water management, how soil acidity can affect crop growth and what growers and agronomists can look for when diagnosing underperforming areas of a field.
 
They also explore practical approaches to managing and minimizing the impacts of soil salinity and compaction, along with how growers can think about soil health, field variability and the factors they can influence to support crop growth.

What Really Influences Soil Organic Matter?

What Really Influences Soil Organic Matter?

September 22, 2026 26:06
Episode notes
Building soil organic matter has become a common goal for farmers looking to improve soil health, but increasing soil organic matter levels can be harder than we'd expect.
 
In this episode, host Amy Crozier is joined by Andrew McGuire, Irrigated Cropping Systems Extension Agronomist and Grant County Director with Washington State University, to explore what influences soil organic matter (SOM) and which management practices can actually help build or maintain it over time.
 
They discuss the balance between biomass inputs and losses, how harvest and erosion affect SOM, the value and limitations of different soil-building practices and debunk the claim that nitrogen fertilizer burns up SOM. Andrew also shares how growers can evaluate soil health products, set realistic expectations and focus on practices that address measurable problems in their fields.
