Total nitrogen content was tested with the machine AutoAnalyzer 3 (SEAL).
A total nitrogen content of up to 11 at.% was reached by the applied conditions.

Total nitrogen content was highly correlated with carbon content (Spearman R = 0.92); therefore variation attributed to carbon could alternatively be due to nitrogen.
In addition, overexpression of NLP7 can increase plant biomass, nitrogen uptake, total nitrogen content, and expression levels of genes involved in nitrogen assimilation and signaling52.
The pretreated manure had a total nitrogen content of 1.3% dry matter (DM) while the original dairy manure had twice that amount with a total nitrogen content of 2.6% DM.
Nevertheless, the urease activity was correlated with the total nitrogen content only on the water erosion-dominated slopes.
This reaction pathway yielded amide and amine functional groups, and a total nitrogen content higher than 3 at.%.
We also tested the total nitrogen content and similar levels were found in the nlp7 mutants and WT, indicating that the nitrate import was not changed in the nlp7 plants (Supplementary Fig. S8).
Concomitantly, the total nitrogen content (%N) measured in sampled A. mangium leaves did not vary according to the block or inoculation treatment.
Significant correlations were found for the catena located in a sandstone area (Catena A) between rice yield and silt as well as total nitrogen content.
