Rhizosphere engineering – modifying soil biophysical properties

1:15PM - 4:30PM, 23 Jan 2024

The ability of roots to extract water and nutrients from soil depends on biophysical interactions in the rhizosphere. However, wetting and drying cycles common to turfgrass can result in soils that remain wettable, while the rhizosphere becomes hydrophobic. This compromises water movement, impacts soil microbial dynamics and inhibits nutrient mineralisation, transport and soil health.

Understanding, predicting and engineering rhizosphere structure enables turf managers to harness plant and microbe interactions and other rhizosphere activities to increase plant and soil productivity and improve responses to a wide range of environmental stresses.

This class will review key research discoveries and detail strategies to enhance turfgrass performance under stress conditions.

Learning outcomes:

  • Develop an appreciation for the dynamic interactions occurring beneath the soil surface
  • Apply strategies to manipulate the rhizospere and rhizobiome to enhance soil and plant health
  • Become familiar with diffusion and flow processes
  • Understand how quickly scientific understanding is developing related to the plant-soil-microbe communication and relevance to real world practices

Dr Stan Kostka

Visiting Scholar Pennsylvania State University

Dr. Stan Kostka, a Visiting Scholar at Penn State – Berks, is a leader in the development of compounds and products to modify the rhizosphere and enhance soil-plant-water relations.

Stan has spent over 25 years leading industry discovery and technology development programs with the goal of understanding how surfactants and other compounds may be used to manage soil water repellency, improve water use, and enhance performance of input chemistries in turfgrass.

He has over 40 publications in the field and holds 15 patents relating to the use of surfactants and polymer technologies to modify soil and rhizosphere properties.
As a globally recognized expert, Stan has been an invited speaker at numerous technical meetings globally in the fields of turfgrass and soil science.

Stan received his PhD in Plant Pathology from the University of Massachusetts, a MS in Plant Science from the University of Connecticut, and a BA in Biology from the College of the Holy Cross in Worcester, MA.

Professor of plant and soil science Pennsylvania State University

Dr. Michael ("Mike") Fidanza is a Professor of Plant and Soil Science at Penn State Berks Campus. His research and teaching focus is plant and soil ecology, the translational evaluation and exploration of plant health products (fungicides, herbicides, plant growth regulators), soil surfactants, seed technology, mushroom compost, biostimulants, turfgrass physiology, cultural practices in turfgrass ecosystems, and the biology and ecology of fairy ring disease in turf. He is a Fellow in the American Society of Agronomy, and Editor of a new turfgrass science textbook - Achieving Sustainable Turfgrass Management.  He teaches undergraduate courses in biology, horticulture, soils, turfgrass science, and a graduate course in plant physiology. He was past president of the Northeastern Branch of the American Society of Agronomy (2013-2017), and past Chair of Division C-5 (Turfgrass Science) of the Crop Science Society of America (2018). He was Editor-in-chief of the International Turfgrass Society Research Journal (2010-2013). He was a member of the USGA Green Section Research Committee (2010-2017).
