La valeur pH de différents sols

Numéro d´article: P1521062

Principle

Information concerning the quality of soils is of great importance for agricultural production. The students are familiarised with this subject via two experiments with pH measurements that show how much soils may differ from each other (experiment  "Characteristic pH values of various soils") and how significant the differences within a soil itself may be (experiment "Soil profile").

Benefits

  • Experiment is part of an experiment set with numerous experiments in ecology
  • Universal handheld measurement device can also be used for other measurement parameters relevant in ecology, biology and chemistry
  • Outdoors measurement possible, for mobile use
  • Graphical display of measurement data
  • Data can be saved on SD memory card
  • All data can be transferred onto a computer for data analysis
  • Data analysis software can be freely distributed

Tasks

  1. Taking soil samples
  2. Identify soil profiles
  3. Measure soil pH

What you can learn about

  • Soil fertility
  • Soil profile
  • Soil horizon
  • Soil sample
  • pH determination
  • Buffer capacity of soils
