Surface soil can fix H2PO4- at a rate of 25 mmol kg-1 in weathered soil. What rate of fertilizer (in kg) as H2PO4- would require to saturate this fixation capacity for one hectare of soil in the top 10 cm depth? P = 31 g mol-1 O = 16 g mol-1 H = 1 g mol-1 (5 marks)   Volume of the soil = Area × depth = 10000m2 × 0.1m = 1000 m3   Mass of soil = bulk density * volume of soil = 1300kgm-3 × 1000 m3 = 1.3 × 106 kg

Weight-Volume relationships

Weight is defined as the quantity of matter contained in a body. Weight can also be defined as the force acting on a body due to gravity. Mathematically, weight can be defined as-
