We have prepared biochars from several agricultural wastes, saturated them with dairy manure liquid and used them as a fertilizer/soil conditioner in a greenhouse experiement.
I already have some literatures and need some more to make my discussion better.
We both would like to see the effects of enriched biochars on plant growth, nutrition uptake and soil quality.
i'm not really sure, but please open this website

Interesting discussion...
Use of biochar as bulking agent for the composting of poultry manure: Effect on organic matter degradation and humification
Abstract : The aim of this study was to evaluate the use of biochar (produced by slow pyrolysis of Eucalyptus grandis biomass) as bulking agent for the composting of poultry manure. Three composting mixtures were prepared by the turned-pile system by mixing poultry manure with different organic wastes used as bulkingagent (biochar, coffee husk and sawdust) in a proportion of 1:1 (fresh weight). Despite the inert nature of biochar, the composting mixture prepared with biochar underwent an organic matter degradation of 70% of the initial content. The organic matter of the poultry manure–biochar mixture was characterised by a high polymerisation degree of the humic-like substances, with a relative high proportion of humic acids in relation to fulvic acids. At the end of the composting process, the humic acid fraction represented more than 90% of the alkali extractable fraction, reflecting the intense humification of this material. Enrichment of poultry manure with biochar reduced the losses of nitrogen in the mature composts, although the use of sawdust would be more efficient in preserving the organic matter and nitrogen in the mature compost.

Abstract :The aim of this study was to assess the effect of a 2% (v/v) addition of biochar on the quality of a composting mixture prepared with poultry manure and different local organic wastes (rice husk and apple pomace). Compost quality was evaluated in terms of typical stabilisation indices, the microbial biomass and selected enzymatic activities related to the C, N and P cycles. The main effects of biochar were a 10% increase in C captured by humic substance extraction and a 30% decrease of water-soluble C, due to an enhanced degradation rate and/or the sorption of these labile compounds into the biochar. The urease, phosphatase and polyphenol oxidase activities of the biochar-blended compost were enhanced by 30–40% despite the lower amount of microbial biomass. Denaturing gradient gel electrophoresis revealed a higher diversity of fungi in biochar-amended compost, suggesting a change in microbial composition compared to the unamended compost.
