Module 2: How Florida Soils Interact with Phosphorus

 

Lecture 1: Overview of Florida soils and their distribution

View on YouTube

Provides an overview of Florida soil morphology, of Florida soil types and distribution, and of how soil morphology gives clues to P dynamics.

 

 

Lecture 2: P dynamics as related to soil morphology and composition I

View on YouTube

Describes the morphological cues to processes affecting distribution of soil components, explains P-retaining components and their distributions, and discusses the value and limitations of soil taxonomy in predicting P loss risks.

 

 

Lecture 3: P dynamics as related to soil morphology and composition II

View on YouTube

Explains phosphate bonding mechanisms, how soil components interact with P, P affinity of soil components, and how component distribution affects P dynamics.

 

 

Lecture 4: Soil & hydrologic factors affecting P transport

View on YouTube

Describes P transport in soil and how distribution of soil components in conjunction with drainage influences P transport.

 

 

Lecture 5: Risk-assessment implications of manure-amended, fertilizer-amended, and naturally-phosphatic soils 

View on YouTube

Explains the nature of naturally-phosphatic soils and how the form of P makes a difference in its potential fate.
