Biochar tablets with and without embedded fertilizer on the soil chemical characteristics and nutrient use efficiency of zea mays

Densification of ashy biochar into tablet can enhance the handling and conveyance efficiencies of biochar. It was hypothesized that fertilizer-embedded biochar tablets can slowly release embedded nutrients in synchrony with optimum nutrient uptake by crops. The objectives of this research were to de...
