Responsibilities and Interests

My current research objective is to maximize fertilizer use efficiency in turfgrass systems. Current projects include evaluation of fertilizer programs, cultural practices for accelerated treatment of acid soil complex, characterization of organic and inorganic soil amendment of turfgrass root zones, and development of soil sampling, analysis, and interpretation protocol on the basis of site and management-specific parameters. Future research directions include soil hydrophobicity causes, identification, and remediation, and transport modeling of nutrients in natural and constructed turfgrass soil systems. I teach Turfgrass Nutrition in the 2- and 4-year programs.

Course Overview

Within this course, we will take a look at turfgrass nutrition and growth with an emphasis on constructed and mineral soil fertility, nutrient uptake and function, and fertilizer use efficiency. The course material presenting this information will be offered within 13 modules.

Module quizzes require students to demonstrate familiarity with the content by identifying and applying concepts and principles introduced in the associated module. There are (11) module quizzes worth a total of 333 points.

The laboratory assessments require students to:

  • compile data provided
  • employ formulas for the transformation of data into more useful forms
  • compare the results of various treatments
  • apply concepts introduced in the associated lesson to make inferences and conclusions from the results

There are four (4) lab assessments worth a total of 200 points.

The turnaround time for graded assignments is generally one week or less.

The midterm exam is worth 210 points and the final exam is worth 275 points. The total point value for this course is 1018 points.

Course Objectives

Upon completion of TURF 435, students will be able to:

  • distinguish the function and requirements of plant nutrients in the turfgrasses
  • describe how physical and chemical properties of soil affect nutrient availability, and select soil amendments to remedy soil chemical limitations
  • discover how best to sample soil, tissue, and water; submit samples, choose appropriate specialty tests, and interpret reports
  • identify fertilizers and application methods to satisfy site-specific nutrient requirements
  • prepare nutrient management plans by appraising edaphic and environmental conditions and current cultural management and use

Academic Integrity

Academic integrity is the pursuit of scholarly activity in an open, honest, and responsible manner. Academic integrity is a basic guiding principle for all academic activity at The Pennsylvania State University, and all members of the University community are expected to act in accordance with this principle. Consistent with this expectation, students should act with personal integrity, respect other students' dignity, rights, and property, and help create and maintain an environment in which all can succeed through the fruits of their efforts. Academic integrity includes a commitment not to engage in or tolerate acts of falsification, misrepresentation, or deception. Such acts of dishonesty violate the fundamental ethical principles of the University community and compromise the worth of work completed by others (see Faculty Senate Policy 49-20, G-9 Procedures, and the Code of Conduct).

Please read the academic integrity guidelines for the College of Agricultural Sciences.

A lack of knowledge or understanding of the University's academic integrity policy and the types of actions it prohibits and/or requires does not excuse one from complying with the policy. Penn State and the College of Agricultural Sciences take violations of academic integrity very seriously. Faculty, alumni, staff, and fellow students expect each student to uphold the University's standards of academic integrity both inside and outside of the classroom.

Educational Equity Statement

Penn State takes great pride in fostering a diverse and inclusive environment for students, faculty, and staff. Acts of intolerance, discrimination, or harassment due to age, ancestry, color, disability, gender, gender identity, national origin, race, religious belief, sexual orientation, or veteran status are not tolerated and can be reported through Educational Equity at the Report Bias page.

Privacy Policies

Copyright Notice

All course materials students receive or to which students have online access are protected by copyright laws. Students may use course materials and make copies for their own use as needed, but unauthorized distribution and/or uploading of materials without the instructor's express permission is strictly prohibited. University Policy AD40, Recording of Classroom Activities and Note-Taking Services, addresses this issue. Students who engage in the unauthorized distribution of copyrighted materials may be held in violation of the University's Code of Conduct, and/or liable under federal and state laws.

Counseling and Psychological Services (CAPS)

Many students at Penn State face personal challenges or have psychological needs that may interfere with their academic progress, social development, or emotional well-being. The University offers a variety of confidential services to help you through difficult times, including individual and group counseling, crisis intervention, consultations, online chats, and mental health screenings. These services are provided by staff who welcome all students and embrace a philosophy respectful of clients' cultural and religious backgrounds, and sensitive to differences in race, ability, gender identity, and sexual orientation.

Accommodations for Persons With Disabilities

Penn State welcomes students with disabilities into the University's educational programs. Every Penn State campus has an office for students with disabilities. The Student Disability Resources website provides contact information for every Penn State campus. For further information, please visit the Student Disability Resources page.

In order to receive consideration for reasonable accommodations, you must contact the appropriate disability services office at the campus where you are officially enrolled, participate in an intake interview, and provide documentation. If the documentation supports your request for reasonable accommodations, your campus' disability services office will provide you with an accommodation letter. Please share this letter with your instructors and discuss the accommodations with them as early in your courses as possible. You must follow this process for every semester that you request accommodations.

Accommodations for Military Personnel

Veterans and currently serving military personnel and/or spouses with unique circumstances (e.g., upcoming deployments, drill/duty requirements, disabilities, VA appointments, etc.) are welcome and encouraged to communicate these, in advance if possible, to the instructor in the case that special arrangements need to be made.

Use of Trade Names

Where trade names are used, no discrimination is intended and no endorsement by World Campus, Outreach and Cooperative Extension, the College of Agricultural Sciences, or The Pennsylvania State University is implied.
