What is the gravimetric method used for?
Think about what measurements you might take from soil samples.

Consider whether the samples are taken from the soil for this measurement.
What does the gravimetric method primarily measure?
Recall the main purpose of the gravimetric method.
True or False: The gravimetric method is non-destructive.
Consider the implications of using samples in this method.
A soil sample has a wet weight of 500 grams and a dry weight of 450 grams. Calculate the moisture content and discuss its implications for irrigation planning.
Use the formula we have discussed and think about how soil moisture affects plant irrigation.
Discuss how you would design an experiment to compare the accuracy of the gravimetric method and another soil moisture measuring technique.
Think about how you would set up the conditions for both methods to meet research standards.
