why would testing the abiotic factors in a field study on the same day be so important?
Remember that ABIOTIC FACTORS are environmental things that does not include living things (such as the soil type, temperature, rainfall etc). It is important to test these factors on the same day because these environmental elements may vary on another day. The temp. for example might be different the next day. you do this to avoid experimental error.
