TRANSCRIPT

  • Soil ChemistryAcidifying the soil or lowering the pHElemental sulfur (effect is temporary)

    Ammonium sulfate (effect is temporary)Aluminum sulfate is also used but not recommended as aluminum is a heavy metal!

  • Soil Chemistry Basic soils often can cause iron chlorosis in plants

    This can be corrected by acidifying the soil or choosing a plant which is tolerant of alkaline soils!

    Intervienal chlorosis: often on acid-loving plants like roses, fruit trees, azaleas and rhododendrons

  • Blue in acidic soils
  • Soil Fertility16 elements required for plant growth

  • Soil FertilityC, H, O from the atmosphere & water

    Macronutrients: N, P, K most often deficient in soils. Also, S, Ca, Mg

    Micronutrients: Fe, B, Mn, Cu, Zn, Mo, Cl
