Understanding the Potassium Cycle

What is the initial step in the potassium cycle that releases potassium ions into the soil?

• Erosion

• Leaching

• Weathering

• Decomposition

How can potassium be lost from the soil, making it less accessible to plants?

• Via mineralization

• Through photosynthesis

• Through root absorption

• By leaching and erosion

What process involves microbes breaking down organic material to release nutrients into the soil?

• Weathering

• Mineralization

• Dust deposition

• Leaching

Which practice can help farmers reduce potassium loss from the soil?

• Overwatering plants

• Ignoring soil tests

• Applying excess fertilizers

• Implementing conservation practices

How can gardeners naturally increase potassium levels in the soil?

• Reducing sunlight exposure

• Using chemical pesticides

• Applying organic amendments like compost

• Planting non-native species
