Biochar from pine forest waste (PFW) was used in greenhouse pot experiments to evaluate plant growth using two levels (2% and 4% wt/wt) of biochar amendments applied to an alkaline, loamy sand soil. Biochar soil additions induced a large decrease in the soil bulk density (from 1.59 to 1.26 g cm−3) and large to moderate increases in gravimetric and...

... Lettuce was chosen for the present study because it is a more responsive crop to nutrients and hence suitable for biochar tests (Upadhyay et al., 2014). Moreover, lettuce is recommended by the International Biochar Initiative for germination tests of biochar materials (Artiola et al., 2012). The present paper assesses the effectiveness of corn cob biochar obtained from a wastewater treatment system in enhancing the agricultural productivity of lettuce plant (L.sativa var. ...
