The Basic Soil-Water-Plant Relationship

March 3, 2021 12:00 pm
Dr. Franklin Gaudi


Plant growth depends on two important natural resources — soil and water. Soil provides support and the nutrient reservoir necessary for plant growth. Water is essential for plant life processes. Effective management of these resources for crops and landscapes requires growers and landscapers to understand relationships between soil, water, and plants. This relationship is significant to irrigation users that desire to use best management practices such as irrigation scheduling. 

In this webinar, you will learn:

  1. The difference between soil texture and soil structure
  2. What saturation, field capacity, and permanent wilting point mean
  3. What soil moisture content is and how to measure it 
  4. Understand soil moisture depletion
  5. Learn why available water holding capacity is important
  6. Understand the science of management allowable depletion
  7. Learn how to do some basic calculations
