How Does Your Garden Grow?

Breakdown of rocks is the primary natural source for Phosphorus and Potassium.

Plants take up Phosphorus and Potassium through their roots for use.

After they die, Phosphorus and Potassium are released back into the soil when the plants decompose.

Algae and other aquatic organisms help Nitrogen, Carbon, and Oxygen cycle through bodies of water.

Fertilizer use can cause pollution when too much Phosphorus is transferred into bodies of water.

Livestock add Nitrogen, Phosphorous, and Carbon to the soil while taking in Oxygen.

Crops take in Carbon and use Oxygen.

Lightning causes chemical reactions in soil to form ammonia and nitrates in the soil.

Volcanic activity releases Nitrogen and Oxygen into the atmosphere.

Burning of fossil fuels uses Oxygen from atmosphere and releases Nitrogen into the atmosphere.

Fertilizers on crops and lawns add Nitrogen, Potassium, and Phosphorous to the soil.
