AgroNum & fungi/bacteria ratios
Healthy soils tend to have decent fungi-to-bacteria ratios (rFB). Malik et al. 2016 (https://lnkd.in/eVwgTW2v) note that the significant role of fungi in litter decomposition and indicate that F:B ratios are linked to higher carbon storage potential. Using georeferenced data from Siles et al. 2023 (https://lnkd.in/e_Qpsh9K) Polyor SAS was capable of illustrating that the soil's inherent productivity with little or no N-fertilizer - i.e. aN1_AgroNum (www.polyor.fr), is in fact higher on soils with higher rFBs, or again that rFBs on soils inherently more productive as inferred via aN1_AgroNum ... have higher rFB values, obviously. Note that aN1_AgroNum is above a function of the soil's indigenous azotobacteria (i.e. free-living, non-symbiotic nitrogen fixing bacteria), also a key component of Polyor SAS's approach to N-fertilizer management (www.polyor.fr). Voila!
