Diana Ita-Nagy

Hello Anda,

I recommend you the following article:

Nemecek, T., Kägi, T., & Blaser, S. (2007). Life cycle inventories of agricultural production systems. Final report ecoinvent v2. 0 No, 15.

Check section 4.4.3 Emissions of phosphorus to water

Cheers!

Anda Fridrihsone

Dear Diana Diana Ita-Nagy ,

Thank you! I`m aware of this document. However, section "P Emissions Through Erosion by Water to Surface Waters"" is the issue for me because I can`t calculate the Ser = quantity of soil eroded. I don`t read German to get familiar with the publication by Oberholzer, the authors refer to. If you could help me with this, I would be very happy and thankful.

Dear Anda, I am sorry I cannot help you more, I am not completely familiar with Oberholzer publication. I will try to find an article I remember used Oberholzer´s study to calculate Ser with the appendix.

Elnaz Amirahmadi

for calculate phosphorus emissions, you can use SALCA model.
