Soil pH Testing Procedures

The video tutorial explains how to determine the pH of soil using the Hillage True OG pH Test Kit. It covers the preparation of the soil sample, the application of liquid and powder reagents, and the colorimetric test to determine pH. The tutorial emphasizes the importance of proper technique in handling reagents and interpreting the color results against a chart. The estimated pH is recorded to the nearest tenth, with a typical range between 6.5 and 7.0.

What is the purpose of using the Hillage True OG pH test kit?

• To determine soil pH

• To assess soil texture

• To calculate soil temperature

• To measure soil moisture

How much of the soil sample should be used in the test?

• A full cavity

• A quarter of the cavity

• A third of the cavity

• Half of the cavity

What is the role of reagent N in the soil pH test?

• It is used to clean the soil sample

• It is a liquid that initiates the reaction

• It is a powder that reacts with soil

• It is a color chart for comparison

What should be done after adding reagent M to the soil?

• Leave it in direct sunlight

• Shake the sample vigorously

• Allow it to stand in the shade

• Add more reagent N

Why is it important to remove the cap by pulling it off rather than unscrewing?

• To prevent spilling the liquid

• To avoid damaging the cap

• To ensure the powder comes out properly

• To keep the reagents fresh

What is the purpose of comparing the developed color to a chart?

• To measure soil temperature

• To estimate the soil pH

• To assess soil moisture

• To determine soil texture

What pH range is estimated for the soil in the video?

• 6.5 to 7.0

• 8.5 to 9.0

• 5.0 to 5.5

• 7.5 to 8.0

What is the recommended precision for entering the pH value in contests?

• To the nearest hundredth

• To the nearest tenth

• To the nearest whole number

• To the nearest thousandth

What is the significance of the colorimetric test in soil pH testing?

• It measures soil moisture

• It provides a visual pH indication

• It calculates soil temperature

• It assesses soil texture
