Question

1. If your sample contained 0.32g H2O/g, how much moist sample would be needed to equal 10g dry soil? 2. Several decades ago, water content of soils was commonly expressed as a percentage obtained by dividing the water content by the dry solids content and multiplying by 100. Expressing water content as a percentage is no longer accepted in soil science. The composting industry continues to use percentages to express water, but calculate those percentages by dividing the weight of water by the weight of the wet sample, such that, a compost at 50% moisture contains 0.5g water/g wet compost, or equal quantities of water and dry solids. Expressing this per g dry solid will be equivalent to 1 g H2O/g dry compost. Compute for the water content in g H2O/g dry solids of a compost which has 80% moisture 1.

Explanation / Answer

1 g moist sample contains 0.32 g H2O.

1 g  moist sample contains 0.68 g dry soil.

hence

0.68 g dry soil is contained in 1 g moist soil

hence

1 g dry soil is contained in 1/0.68 g

hence 10 g dry soil is contained in 10/0.68 = 14.7058 g
