Can Biochar and LMWOAs (Organic acids ) Be Jointly Used as a solution for phosphorus use efficiency in highly P fixing soils !
Yes why not , rarher it will be doubly effective to ensure both short term as well as long term improvements in soil properties and associated crop response. This is the biggest limitation with current use pattern of biochar that falls short of short term crop response established throygh variety of field studies...
Low molecular weight organic acids enhances inorganic P release into soil solution , thereby increases plant available Pi in soils. Mixing bio-char with low molecular organic acids may influences the potential of bio-char as a soil amendment and tool for carbon sequestration.
Yes, but it would be better to use acid-producing microorganisms + biochar. Microorganisms could provide additional benefits (plant hormones, better soil structure, etc.). You can also use animal biochar, with better characteristics (higher P content, lack of metals, etc.).

Thank u Nikolay
plz give me an answer, where we can find acid-producing microorganisms ? is't possible to get / separate acid-producing microorganisms from an laboratory experiment ??
Yes, can be used. and this subject has a wider scope to conduct more comprehensive research, as much work has not been done yet.
Bacterial strains produce organic acids including citric, lactic, succinic, gluconic, and itaconic acid.
Different types of media are used for production e.g. citric acid is made by fermentation of Aspergillus niger and starch based media.
Moreover, Biochar plus acid producing microorganisms can possibly enhance soil quality and health to increase PUE.
