Crop husbandry — rotation, fertilisation

What you'll learn

1. 1

   Imagine a field of wheat. If you grow the same crop every year, the soil gets tired and pests build up.

2. 2

   What is the main reason farmers rotate crops?

3. 3

   Plan a 3-year rotation for a field. Year 1: wheat (heavy feeder). Year 2: beans (adds nitrogen). Year 3: grass (rests soil).

4. 4

   Fertilisation gives plants extra food — like a vitamin boost. Nitrogen helps leaves grow, phosphorus helps roots, and potassium helps flowers and fruit.

5. 5

   A farmer tests soil and finds low nitrogen. Which fertiliser should they use?

6. 6

   Which nutrient helps leaves grow green and big?

7. 7

   Drag the correct fertiliser bag to the field that needs it. Field A has yellow leaves (low nitrogen). Field B has weak roots (low phosphorus).

8. 8

   Why should farmers test soil before adding fertiliser?
