Path of Soil in a Soil Testing Lab

Path of Soil in a Soil Testing Lab Professor DeBacco Here you will see a step by step process soil takes through the University of Connecticut Soil Lab. Thanks Dawn! Basic Process Receiving remember your paperwork! This is where the soils are first processed in the lab Paperwork and payment is typically checked Drying Samples are initially dried and while growers should not be sending wet samples, this allows for a consistent moisture level for all samples Grinding/sifting This will screen out larger material to allow for consistent particle size of the actual soil to be processed. Sub sampling Of the sample provided a consistent volume will be removed to continue the analysis process Running the ICP (Inductively Coupled Plasma) Extremely high heat (8000degrees-C) causes elements to become thermally excited and emit light which the intensity is measured Organic Matter (LOI) Sample needs to be burned to determine organic and mineral content Sand Silt and Clay The particle composition can be important in some applications pH Separate test to determine the concentration of hydrogen ions in solution Phosphorus Run on a sperate machine Report is end result Final results are compiled and recommendations are provided based on the crop selected Link to Lecture Slides: https://drive.google.com/file/d/1IhLq... *Due to the description character limit the full work cited for "Path of Soil in a Soil Testing Lab" can be viewed at... https://drive.google.com/file/d/1k-D3...
