(1b) The sandy soil sample B has a lower water retention capacity compared to the clay soil sample A. Sandy soil has larger particles and larger pore spaces, allowing water to drain through more quickly and reducing its water-holding capacity.

(1c) Calculation of the percentage of water retained:
(i) Cylinder A:
Percentage of water retained = (Water collected / Water added) x 100
= (10 cm³ / 30 cm³) x 100
= 33.33%

(ii) Cylinder B:
Percentage of water retained = (Water collected / Water added) x 100
= (25 cm³ / 30 cm³) x 100
= 83.33%

(iii) Two crops that could thrive in clay soil (sample A):
– Wheat
– Rice

Two crops that could thrive in sandy soil (sample B):
– Maize
– Sunflowers


I. Incubator
Uses: to provide warmth for livestock
II. Panga
Uses: for cutting
III. Syringe and needles
Uses: for giving livestocks drug
IV. Feedrack
Uses: for giving livestocks feeds and water
V. Weighing balance
Uses: for measuring weight of livestocks

The seeds are planted in the farm tool containing the required soil. The set up is placed in the sun with frequent supply of adequate water. After leaving for few weeks,the seeds starts to germinate and it’s then transplanted to the field properly.


Plant Population=
Area of farmland/spacing

Plant population= (3 hectares × 10,000m²/hectare)/ 1m × 0.5m

Plant population= 10,000m²/0.5m²

Plant population= 60,000

Land area: 5 hectares= 50,000m²
Spacing: 1m×1m = 1m²
Germination Percentage: 90%

Plant population(maize) = (50,000m²/1m²) × (90/100)

Plant population= 50,000 × 0.9

Plant population= 45,000

(i) Water
(ii) Temperature
(iii) Oxygen

(i) Regular weeding
(ii) Proper spacing
