Good measurements are key for tackling the nitrogen challenge. Our landmark course gives you guided training in everything from greenhouse gas flux measurements, through ammonia flux measurements, to a number of plant and soil nitrogen measurements.
We have to feed the world population but, currently, we do this at the expense of environment, climate and human health due to nitrogen pollution from the use of fertilizers. This is the nitrogen challenge, one of the biggest environmental challenges of the 21st century.
Developing and improving nitrogen science globally could bring us closer to the solution. To do this, good measurements are key, providing us with information on the nitrogen status of the soil and the plants it nurtures. This can help us in understanding the underlying processes, establishing a solid basis for effective nitrogen management strategies.
In this course, we provide training in:
The scientists of the South Asian Nitrogen Hub bring you guided training videos on measurement methods and laboratory analyses accompanied by detailed descriptions of procedures and calculations, as well as many downloadable materials useful both on the field and in the lab.
We recommend taking the Nitrogen: A Global Challenge course first.
Week 1: Introduction to nitrogen-related field measurements
Introduction to the measured gases (ammonia and greenhouse gases) and the process of leaching.
Week 2: Greenhouse gas flux measurements using closed chambers
Principles of closed static chamber measurements, how to install a chamber and take samples, how to analyse samples and calculate fluxes.
Week 3: Ammonia measurement with a dynamic chamber
Introduction to dynamic chamber measurements, how to build and install a chamber, how to take samples, lab analysis and flux calculations.
Week 4: Plant and soil nitrogen measurements
How to collect plant samples and analyse them in the lab, principles of soil and leachate sampling, physical and chemical analysis of soil and leachate samples, calculation of the nitrogen budget.
