Description
Abdallah Barakat and co-authors test bone char, a phosphorus-rich charcoal made from bones, as fertilizer for spinach in chalky sandy soil, in a 2025 pot study. Such soils lock phosphorus away from plants. Twelve treatments mixed bone char with sulfur or humic acid, tried acid-treated char, and compared rock phosphate.
Every treatment freed more phosphorus than the untreated soil. The strongest mix, modified bone char plus humic acid, raised available phosphorus from 11.6 to 26.1 milligrams per kilogram. Spinach shoots grew heavier under most mixes, with bone char plus humic acid on top for fresh weight. Weighing cost, the authors favor bone char with sulfur as the practical best buy.
