Nano-Black Carbon Improve Phosphorus Uptake, and Sustain Soil and Plant Health Under Biodynamic Agriculture

ABSTRACT
Numerous factors, such as the soil’s low organic content and the inaccessibility of phosphorus nutrients in acidic soil conditions, restrict the growth of crops and the health of the soil. In the 21st century, crop production and soil health need attention for food security in order to enhance soil fertility and vigorous crop production. The objective of the study was to investigate how biodynamic farming affects on soil health and plant biomass production as phosphorus can react with aluminum and iron in acidic soil to generate insoluble compounds that are unavailable to plants. Phosphorus availability in acidic soil might be a problem and less available to plant roots as a result of the precipitation. By lowering the solubility of aluminum and iron in acidic soils, nano-black carbon increases the availability of phosphorus to plants. Experimental findings revealed that grain phytate concentration and fertilizer use-efficiency were significantly improved with agronomic interventions. The highest GPC and TPU were noted with nano-black carbon tretament. However, SPU was increased with muck compost application. The maximum GPC, SPU, and TPU were recorded at 100 kg P ha−1. Maximum GPC, SPU, and TPU were recorded with Trichoderma achlamydosporum than Pseudomonas. Highest FUE was recorded with 75 kg-P-ha−1. AE and PFPp altered with treatments and highest AE and PFP were noted with nano-black carbon. Conclusively, PAE, PFPp, and FUE were higher with integration of nano-black carbon+achlamydosporum along with inorganic P (75 kg per hac) can improve soil health and nutrients status along with yield and productivity on a sustainable basis.
