Lecture 1: Welcome and course overview

View on YouTube

Introduces the instructors and outlines the course structure, objectives, and the content for each module.

 

 

Lecture 2: Sampling soils for P risk assessment

View on YouTube

Describes tools and techniques for sampling upland and wetland soils and how to prepare a soil for analysis.

 

 

Lecture 3: Conventional techniques for evaluating phosphorus release from soils - water soluble P and soil test P

View on YouTube

Explains water soluble phosphorus (WSP) as an important parameter in P-related issues, the extraction procedure for WSP, and soil testing for phosphorus, including choice of extractant and the extraction procedure for Mehlich 1-P, and compares two procedures for phosphorus analysis.

 

 

Lecture 4: Oxalate-extractable P, iron-oxide strip P, and total P

View on YouTube

Shows the laboratory techniques for evaluating P dynamics in soils and sediments by determining P extracted from soils, including oxalate-extractable P, iron-oxide strip P, and total P in soil.

 

 

Lecture 5: Soil phosphorus fractionation procedures

View on YouTube

Explains why soil P fractionation procedures are performed and compares fractionation schemes and their modifications.
