Worked Solution & Example Answer:A field trial was carried out to investigate the effect of mass of phosphate fertiliser applied on the growth of barley - Scottish Highers Biology - Question 11 - 2018
Step 1
Randomise the treatment plots.
Answer
Randomising the treatment plots helps to reduce bias and ensure that any environmental factors, such as soil moisture content, are evenly distributed across the different treatment groups. This allows for a more reliable comparison of the effects of varying phosphate fertiliser masses on barley growth.
