Workshop Topics and Goals

This program will focus basic principles of plant growth and development, so that growers will understand how environmental and cultural practices affect plant growth and quality. There are five parts to this workshop:

  1. Basic physiological processes of plant growth and development
  2. Plant Hormones
  3. Plant essential nutrients and how they are taken up and assimilated
  4. Fertilizer, media, soil and irrigation practices to optimize nutrient uptake
  5. Environmental and cultural practices impacts on plant production

A simple overview of key physiological processes and the plant hormones will be explained. This is essential for growers to understand how fertilization, irrigation, environment and cultural practices affect plant growth and development. In the third and fourth parts of the program, we will describe the plant essential nutrients, how much is needed in the plant, and how to calculate fertilizer rates. We will then teach growers how to troubleshoot production problems related to nutrient deficiencies, toxicities and how to correct these problems. In the final part of the workshop, we will review environmental effects on plant production:

  • Temperature – daily fluxes, seasonal fluxes, media vs. air temperature
  • Light – quality, quantity, duration and location
  • Environmental stresses – heat, cold, light, drought, poor water quality –salt

By the end of the program, participants will be able to:

  • Identify symptoms of key nutrient disorders
  • Calculate nutrient content from various fertilizers
  • Identify cultural practices and environmental conditions which may impact optimum fertilize use
  • Customize fertilizer application programs to individual needs to optimize nutrient uptake and reduce nutrient runoff from nursery production facilities and landscapes
  • Have a better understanding of how various production practices influence plant growth
  • Develop BMPs customized to specific crop needs
