- aSolar energy = (the average radiation of province) × (area)
- The average radiation of province = 17.5 MJ/(m2 day) = 6,387.5 MJ/(m2 year)
- bGlobal wind circulation = (0.4 J/m2/sec) × (3.15E+7 sec/year) × (area)
- cEvapotranspiration, chemical energy = (area) × (average rainfall) × (density) × (Gibbs free energy)
- Average rainfall = 2 m/year
- Density = 1.00E+ 06 g/m3
- Gibbs free energy = 4.94 J/g
- dNet loss of topsoil = (soil loss) × (organic matter content) = 9.5 t/ha × 2.5 ha
- Soil loss = 9.5 t/(ha year)
- Organic matter content = 20% = 0.2
