e1“Soil contamination with iron had relatively little effect on the heat of combustion and calorific value of biomass and very strongly reduced plant height (42%), dry matter yield (95%) and energy production of maize biomass (90%), the SPAD index at the fifth leaf unfolded stage (44%) (as opposed to the stem elongation stage), sodium, magnesium and phosphorus contents, and increased calcium, potassium and nitrogen contents of maize”

Other claims from this paper (13)
- Intervention effect Soil iron contamination had relatively little effect on the heat of combustion and calorific value of maize biomass.
- Intervention effect Soil iron contamination very strongly reduced maize plant height by 42%.
- Intervention effect Soil iron contamination very strongly reduced maize dry matter yield by 95%.
- Intervention effect Soil iron contamination very strongly reduced energy production of maize biomass by 90%.
- Intervention effect Soil iron contamination very strongly reduced the SPAD index of maize at the fifth leaf unfolded stage by 44%, as opposed to the stem elongation stage.
- Intervention effect Soil iron contamination decreased sodium, magnesium and phosphorus contents of maize.
- Intervention effect Humic acid application increased maize plant height by 22%.
- Intervention effect Humic acid application increased maize dry matter yield by 67%, a significant increase.
- Intervention effect Humic acid application increased energy production from maize biomass by 62%.
- Intervention effect Humic acid application changed the heat of combustion and calorific value of maize biomass minimally but positively.
- Intervention effect Humic acids decreased the SPAD index of maize during the stem elongation phase.
- Intervention effect Humic acids decreased the content of all macronutrients in maize biomass, as a result of a reduced effect of iron on macronutrient content.
- Recommendation Humic acid application appears to be an effective adjunct in phytostabilisation of iron-contaminated soils by growing maize for energy.
