Biochars pyrolyzed from plant residues and animal manure feedstocks may contain disproportionate amounts of phosphorus (P) and potassium (K). Unequal nutrient characteristics can impact the biochars ability to properly supply as well as improve soil P and K fertility levels.
Lignocellulosic based biochars, and that feedstock blends can be used to create designer biochars that align soil test fertilizer values with plant nutrient improvement.

Primarily biochar just facilitates slower release and hence greater retention time for the nutrients

Biochar generally works as a carbon sink in the soil and it will definitely release some important plant nutrients viz. N, P, K and S and some extent Cationic Micronutrients.
The formulation with slow release of biofertilizer is the most important application of Biochar and see biofertilizer formulation produced with biochar and microbial innoculants. Diffusion of the know is the challenge for farmers especially in Africa and see attached pictures.
Biochar helps to retain water, bind soil particle together, prevent leaching and release of nutrients to the soil which plant can easily utilized.
The best application of biochar is slow release of nutrients. That is what i use it for in my biofertilizer formulation.

The biochar also increases the water and nutrient holding capacity of soil. thus increasing the nutrient availability to plants and prevents the nutrients from fixation and leaching
The science of biochar should be promoted by extension workers to farmer because of its great impacts on soil health.
Biochar (BC) is the porous carbonaceous solid produced by thermo chemical conversion of organic materials in oxygen depleted atmosphere which has physiochemical properties suitable for safe and long-term storage of carbon in the environment and potentially soil improvement. Biochar improves soil water holding capacity and facilitating seedling biomass gain. Plant growth responses can be altered by biochar induced changes in soil nutrient conditions, particularly the cycling of P and K . Biochar improves the physical conditions around the crop-root zone and enhanced crop production .
Jan, from the paper, The P sources included two organic sources i.e. Farmyard manure (FYM) and poultry manure (PM) and an inorganic source i.e. diammonium phosphate (DAP) could have had a better result with the application of biofertilizer from filed application case study.
Biochar has the ability to improve soil fertility, leading to higher crop yields. Applied to the soil in a finely ground form, biochar’s vast surface area and complex pore structure is hospitable to the bacteria and fungi that plants need to absorb nutrients from the soil. So, biochar provides a secure habitat for beneficial microbial activity that is important for crop production to flourish.

Biochar enhance effective microbes but we must improve shelf live of biochar products.
Coal has a microbial porous structure that prepares the ground for soil fertilization, where coal increases nutrients, reduces soil leaks, and enhances the plant's ability to absorb them and thus increase the production of the crops.
The most import part of biochar is the applied application for
phytobiomes +microbiomes in soil fertility management during crop cultivation.
