Understanding the Basics of Soil and Plant Health & How Conventional Practices Affect Turfgrass Disease Susceptibility, Darcy Lepine
Part 1 (30 minutes):
Slide 1: Introduction to Turfgrass Management and Disease
● Text: Turfgrass management involves practices to maintain healthy lawns, golf courses, and sports fields.
● Key Concept: Soil and plant health directly influence disease resistance and susceptibility in turfgrass.
Slide 2: What is pH and Redox Potential (Eh)?
● Text: pH measures soil acidity, while Eh (redox potential) indicates the soil's oxidation-reduction state.
● Key Concept: Both pH and Eh play critical roles in nutrient availability and plant health.
● Graphic: Infographic showing pH scale (acidic to alkaline) and Eh spectrum (oxidizing to reducing).
Slide 3: The Importance of Homeostasis
● Text: Plants maintain homeostasis of pH and Eh to stay healthy. Imbalances can weaken turfgrass and make it more susceptible to diseases.
● Key Concept: Turfgrass thrives when pH and Eh are in the optimal range, but stressors can disrupt this balance.
● Graphic: Diagram showing a healthy plant maintaining homeostasis with balanced pH and Eh.
Slide 4: Turfgrass Stress and Disease Triangle
● Text: The "disease triangle" includes the plant, the pathogen, and the environment.
● Key Concept: Environmental stressors (like extreme pH/Eh) increase turfgrass susceptibility to pathogens.
● Graphic: Disease triangle with labels: Pathogen, Turfgrass, Environment.
Slide 5: Stress Factors Affecting Turfgrass Health
● Text: Factors like drought, soil compaction, and improper fertilization can alter pH and Eh, weakening turfgrass.
● Key Concept: These stressors
Part 2 (30 minutes):
Slide 8: Introduction to Conventional Turfgrass Practices
● Text: Conventional practices, such as over-fertilization, frequent irrigation, and pesticide use, can disturb pH and Eh balance.
● Key Concept: These disturbances increase disease susceptibility.
● Graphic: Illustration of conventional turf management practices (irrigation, fertilization, pesticide application).
Slide 9: Impact of Over-Fertilization on Soil pH and Eh
● Text: Excessive nitrogen fertilization lowers soil pH and increases turfgrass vulnerability to diseases like brown patch.
● Key Concept: Proper nutrient management is essential for maintaining soil health and disease resistance.
● Graphic: Before-and-after chart showing how over-fertilization affects pH levels.
Slide 10: The Role of Irrigation in Turfgrass Health
● Text: Over-watering can reduce soil Eh, creating anaerobic conditions that favor certain pathogens.
● Key Concept: Controlled irrigation helps maintain the balance of pH and Eh in the soil.
● Graphic: Line graph showing the relationship between irrigation levels and soil Eh.
Slide 11: Pesticide Use and Its Effect on Soil Microbial Health
● Text: Heavy pesticide use can kill beneficial microbes that help maintain pH and Eh balance, making turfgrass more prone to disease.
● Key Concept: Reducing pesticide use can improve the soil's natural defense against pathogens.
● Graphic: Pie chart showing the effect of pesticide use on soil microbial health.
Slide 12: Sustainable Turfgrass Management Practices
● Text: Practices such as proper aeration, organic fertilizers, and efficient watering can improve pH and Eh homeostasis.
● Key Concept: Sustainable practices help maintain healthier, more disease-resistant turfgrass.
● Graphic: Infographic comparing conventional vs. sustainable turfgrass management practices.
Slide 13: Case Study: Impact of pH and Eh Management on Disease Prevention
● Text: A study showed that turfgrass managed with balanced pH and Eh had fewer diseases compared to over-fertilized and over-watered turf.
● Key Concept: Practical application of pH and Eh management can significantly reduce disease outbreaks.
● Graphic: Bar chart comparing disease incidence in conventional vs. sustainably managed turf.
Slide 14: Conclusion and Key Takeaways
● Text: Conventional practices can increase turfgrass susceptibility to diseases by disrupting pH and Eh. By adopting sustainable practices, turfgrass managers can improve plant health and reduce disease pressure.
● Key Concept: Proactive management of pH and Eh through sustainable practices is the key to healthy, disease-resistant turfgrass.

Interesting Characteristics of Peat Based Fertilizer, John Pocock
It’s well known that peat-based organic matter helps build soil structure, retain water, and increase microbial activity, all beneficial characteristics to maximize plant health. New research, first used in BC 4 years ago, is showing that peat-bound nutrients provide a more natural, even release of micro and macronutrients without “dumping” like coated slow-release products while carbon bonds reduce nutrient loss from leaching and volatilization processes.
Each homogenous peat-based granule contains all nutrients reducing granular fertilizer inputs by some 28-32%. The ability for humic sources to "mine" bound up nutrient in the soil, with this process is truly cutting edge.

Nano particle Research/Minimizing Soil Inputs/Water Savings from Si use, Dr. John Dempsey
Part 1 of this session (1 hour) focusses on new technology and research into the use of nano-particles. A nanofertilizer refers to a product that delivers nutrients to crops in one of three ways. The nutrient can be encapsulated inside nanomaterials such as nanotubes or nanoporous materials, coated with a thin protective polymer film, or delivered as particles or emulsions of nanoscale dimensions. Research has shown that this delivery leads to comparable, and/or enhanced levels of growth, turfgrass quality, tissue, and soil nutrient levels, versus applications of conventional NPK inputs with full rate PGRs and surfactants.
Part 2 of this session (30 minutes) will cover worm control (no death, just removal from the treated area) with Si technology.
Part 3 of this session (30 minutes) refers to the use of Si as a water management tool. The use of supplemental Silica as a fertilizer at very low rates is well known to reduce water usage and improve overall plant health and enhancing the playable conditions for golf, soccer, and other field sports in Europe.
