Northwest Mo | urea about 45# per cu ft, MAP DAP about 60-62# per cu ft, Potash 65-70# per cu ft. Weight will depend upon manufacturer .
Have to use some geometry to calculate your cu ft. Fertilizer can put a lot of pressure on side walls, special construction needed. Wood and concrete for construction. Fertilizer is hydroscopic and draws moisture on hi humidity days. good luck | |
