Hello and welcome to Wikipedia. Hopefully you'll continue editing. My apologies for reverting your first edit – you made a small mistake. Invasive Spices ( talk) 23 June 2022 (UTC)
- Hello, thank you for your message. I have followed your new link, I believe the problem remains. The article is claiming 5-21% of all fixed carbon is transferred to the rhizosphere via exudates. You reference the review paper by Walker, linked here...
- This article makes the 5-21% claim and refers to another paper by Marschner et al (1995), linked here...
- This article concerns phytosiderophore activity in barley roots, which concerns iron uptake. The article makes no reference to carbon rhizodeposition, and the claim of 5-21% of photosynthetic carbon being exuded is absent. The best estimates we have of this are in the paper by Jones et al, linked here...
- The most accurate estimate is ~5% of fixed carbon is rhizodeposited, given the difficulties in assessing, as the article describes. I hope you will include this in this article, many thanks for reading.
5-21%Walker refers to Marchner 1995 [1]. (You are correct that Marschner et al. 1987 [2] is about barley and iron but the
5-21%claim comes from the 1995 book.)
soil residues, pertains to shoot stage plants and is the result of tests in CO2 injected chambers.
exactly what % of photosynthetically fixed carbon is transferred from plants to the rhizosphere via root exudates. Your text reflects that and so I reverted my reversion. Invasive Spices ( talk) 24 June 2022 (UTC)
