Soil, Lake and Air acidity

Soil, Lake and Air acidity

1. Soil

   • Ideal pH: 5.5 to 7.0
     • Ideal for most plants
     • makes it acidic
       • Organic matter and minerals that break down
       • too much water
         • washes out Mg, K, Ca
           • help soil to stay in its ideal pH
       • use of too high-nitrogen synthetic fertilisers
         • contain ammonia
       • Acid rain
         • atmospheric water reacts with sulfur and nitrogen compounds
           • polution
           • makes it acidic
             • kills some kinds of plants and animals
       • deficiency in some nutrients needed for plants
         • affects plant growth
   • neutralizing soil
     • adding agricultural limestone
       • acidic soil + lime = neutral clay + Water+ Carbon Dioxide + Aluminum Oxide

2. Lake

   • Ideal pH: 6 to 8.5
   • Acid Rain
   • Rain that brings impurities to the water when the soil is dirty
   • neutralizing water
     • synthetic magnesium oxide + water
   • Makes it acidic

3. Air

   • makes it acidic
     • pollution
       • Acid gases thats cause pollution
         • Natural causes: Volcanoes
         • Man-made: Industries
       • causes acid rain
       • can travel really far
       • can cause breathing problems
   • neutralization
     • filtering the air
