#Permaculture, #NoTillMarketGardening, #ConservationAgriculture & #SyntropicAgroforestry all rely on #naturalNitrogen found in every #living organism, by restoring the #naturalNitrogenCycle (with #nitrogen just one among others: #carbon, #phosphorus). #SyntheticNitrogen is the crutch of #hasty, destructive, non-#regenerative #agriculture.

Drawing of Phosphorus as a singing mermaid (music notes scattered all over the purple background, given three faint red lines on it).

Lihua Zhang et al. disscussed the #SpatiotemporalDynamics of homeostasis(H) values of microbial #Carbon (C), #Nitrogen (N), and #Phosphorus (P) across biomes. #LandUseandManagement may led to the decoupling of P from C and N metabolism over time and across space.

Temporal variations in H values of microbial biomass C (a), N (b), and P (c) between managed and natural ecosystems. Purple points represent managed ecosystems (M), while gray points represent natural ecosystems (N).

Yumeng Guo et al. showed that the #AbovegroundNetPrimaryProductivity (ANPP) of the temperate typical steppe in #InnerMongolia were not limited by #Phosphorus. Whereas, under #Nitrogen addition, P addition significantly increased the ANPP and the aboveground biomass of forbs.

The effects of P addition on aboveground biomass of grasses and forbs under ambient and N addition conditions.

Taiki Mori et al. found that long-term #Phosphorus (P) addition in #TropicalForest soil did not alter the PME( #Phosphomonoesterase ):PDE( #Phosphodiesterase ) ratio in primary and secondary forests, whereas P fertilization elevated the PME:PDE ratio in planted forest. These results were different from the previous results.

Effects of P addition on the ratio of PME and PDE activities (PME:PDE ratio) in (a) primary forest, (b) secondary forest and (c) planted forest.

How do #SoilMicroorganisms respond to increasing #PlantSpeciesDiversity (PSD) when #MicrobialResource limited ?
The conclusion is: Increasing PSD aggravates microbial #Phosphorus limitation but alleviates microbial #Carbon limitation in a #SubtropicalForest.

Jingyuan Yang et al. explored the effects of #Nitrogen and #Phosphorus addition on #SoilRespiration in a #Soybean cropping system.
1️⃣ Nutrient addition treatments presented significantly negative effects on soil respiration.
2️⃣ Phosphorus addition and nitrogen–phosphorus co-addition strongly inhibited #SoybeanNodulation by changing soil #pH value.

Structural equation model (SEM) analysis of N and P addition-induced causal relationships among Nitrate, Soil pH, available P, number of nodules, Microbial biomass carbon, Root biomass, and soil respiration (Soil R) under P addition and N addition treatments in pot soybean (χ2 = 15.203, df = 23, P = 0.887, CFI = 1, RMSEA < 0.001).
