1 - Nutrient Cycles
Plants require selected nutrient ions which are released as a result of decay - a portion of nutrient cycling. This location includes basic information about nutrient cycling of plant nutrients.
2 - Plant Nutrients
A listing of the essential micro and macro elements required for normal growth of plants.
3 - Essential Elements for Plant Growth: List of Essential Elements
An outline of inorganic elements required for plant growth.
4 - Essential Elements for Plant Growth: Macro and Micronutrients
This site provides qualitative and quantitative information about elements required by plants.
5 - Essential Elements for Plant Growth: Primary and Secondary Nutrients
The soil as a source of primary and secondary plant nutrients. Limiting elements are noted.
6 - Essential Elements for Plant Growth: The Law of the Minimum
The element in most limiting supply determines the plant growth response - according to the Law of the Minimum.
7 - Nutrient Deficiencies
The characteristic nutrient deficiency symptoms of plants is outlined at this site.
8 - Essential Elements for Growth: Nitrogen
Nitrogen supply is often limiting in the environment. Nitrate and ammonium ions are discussed at this site.
9 - Essential Elements for Growth: Phosphorus
Phosphorus is incorporated into many critical metobolites. This requirement is discussed.
10 - Essential Elements for Growth: Potassium
Potassium is commonly added to general purpose fertilizers. The role of potassium is discussed.
11 - Solubility of Plant Nutrients
The acidity of the soil is a primary factor in determining nutrient availability. This presentation includes the importance of pH and provides a link to the Florida Information Retrival System.
12 - What is Plant Nutrition?
This site includes a basic discussion of plant nutrition and relates the importance of soil characteristics.
13 - Plant-Microbe Metabolism
This presentation outlines the importance of nitrogen fixation and extends the information to a variety of links associated with nitrogen fixation.
