Answer 1

Answer:n a situation where there is no information on the soil bulk density. The conventional way of obtaining concentration in mg/kg from kg/ha, is to divide the value in kg/ha by 2.24.

This is based on the fact that the concentration of soil in the pot is in mg/kg, which is the same thing as part per million (ppm). To express ppm in kg /ha, an acre furrows of soil weigh approximately 2,000,000g.

ppm x 2 = pound per acre (ib/ac) and ib/ha is a old unit, ib/ac is converted to kg/ha by multiply it by 1.12.

Therefore, converting 100kg DAP ha to mg/kg will be by

100/2.24 = 44.64 mg/kg soil, 44.64 x 2.5 = 111.61mg/2.5kg soil. You need 111.61mg of DAP per pot
