Soil Testing Review

Front

What is the percentage of potassium typically found in fertilizers?

Back

Fertilizers can vary, but a common percentage of potassium found in fertilizers is 10%.

Front

How do you determine the texture of soil using the soil triangle?

Back

The soil triangle is used to classify soil texture based on the percentages of sand, silt, and clay. For example, a soil sample with 30% clay, 30% sand, and 40% silt is classified as clay loam.

Front

What is the preferred measurement for salinity when testing soil samples?

Back

The preferred measurement for salinity when testing soil samples is low.

Front

What is the typical percentage of nitrogen found in fertilizers?

Back

A common percentage of nitrogen found in fertilizers is 32%.

Front

What happens to soil permeability when soil compaction increases?

Back

When soil compaction increases, the permeability of soil decreases.

Front

What are the three main components of soil texture?

Back

The three main components of soil texture are sand, silt, and clay.

Front

What is the role of potassium in plant growth?

Back

Potassium is essential for plant growth as it helps in water regulation, enzyme activation, and photosynthesis.

How does soil texture affect water retention?

Back

Soil texture affects water retention; clay soils retain more water than sandy soils due to their smaller particle size and greater surface area.

Front

What is the relationship between soil compaction and root growth?

Back

Increased soil compaction can hinder root growth by reducing pore space and limiting oxygen availability.
