Moderator: Julie Newman, UCCE, Ventura County
Presenters: Dr. Don Merhaut, UCCE Specialist for Floriculture/Nursery Crops, UC Riverside
Dr. Lea Corkidi, Postdoctoral Researcher, Department of Botany and Plant Sciences, UC Riverside

This program will provide an in-depth training on all essential plant nutrients and their use in fertilizers.  In addition, instruction and hands-on demonstrations of fertilizer injectors will be provided.  By the end of the program, participants will be able to incorporate Best Management Practices (BMPs) to mitigate fertilizer runoff.  The program will be broken down into six areas:

General overview of BMPs

Overview of nitrogen cycling in watersheds and nurseries

BMPs for Granular Fertilizers

BMPs for Liquid Fertilizers

BMPs for Irrigation

BMPs for Nursery Infrastructure



7:30 am - 8:00 am Registration and Refreshments

8:00 am - 8:30 am Introduction: Fertilizer BMPs and Ag Waiver/TMDL Programs- Julie Newman

8:30 am – 9:30 am  Welcome and Part 1

A review of key plant physiological concepts will be taught, so that applied concepts of plant nutrition and fertility management, which will be taught during the later half of the course, are clearly understood.

9:30 am – 9:45 am


9:45 am – 12 noon
Part 2

Each of the essential plant nutrients will be discussed in detail, emphasizing:

Cycling of the nutrient in the environment (soil, air, water, and plants)

EPA guidelines and state and regional regulations pertaining to that element, if any.

Fertilizer formulations containing the element.  Participants will be taught how to calculate nutrient content from fertilizers commonly used in the industry.

Nutrient disorders of each element will be discussed, emphasizing plant symptoms of plant deficiencies.

Environmental and cultural practices will be discussed that may cause nutrient disorders or reduce the efficiency of nutrient uptake into plant.

12 noon – 12:30 pm


12:30 pm – 2:30 pm   Part 3

Fertilizer Management (Best Management Practices).  The appropriate use of specific fertilizer formulations will be discussed, with a focus on minimizing fertilizer costs through optimization of nutrient uptake into the plants with minimal nutrient leaching. The use of fertilizer injectors will be demonstrated.

Coated Controlled Release fertilizers

Liquid Fertilizers

Granular Fertilizers
