Q4a) Describe a four-bed
system of crop rotation, with the use of a clearly labelled table.(4 marks)
b) State THREE benefits and THREE
limitations of crop rotation. (6 marks)
This question relates
directly to 3.6 of the syllabus:
Part a) requires a simple
table to be drawn. An example of an answer for this would be:
An important part of the order of crop rotation is to follow legumes which may add nitrogen to the soil with the heavy feeding brassicas. Onions are often included with the root crops. The table may be easier to fill in correctly if you write the crops in diagonally!
Part b) has the numbers of benefits and limitations typed in bold and italics to make it clear. It is a good idea to answer these types of questions using numbers or bullet points to check you have the correct number of points.
The examiner’s comments state that the following answers were acceptable: benefits and limitations:
It is important to provide a heading for benefits and limitations, and to only include three points for each part.
