Question

Differentiate between:


(a) Fertiliser and Manure [2 marks]
(b) Seed drill and Funnel sowing [2 marks]

Answer 1

(a) Fertiliser and Manure (0.5 * 4 = 2 marks)

$$\begin{array}{cccc}& \text{Fertiliser}& & \text{Manure}\\ \text{i.}& \text{A fertiliser is an inorganic salt.}& i.& \text{Manure is an organic substance obtained by decomposition of animal and plant waste.}\\ \text{ii.}& \text{A fertiliser is prepared in factories.}& ii.& \text{Manure can be prepared in the fields.}\\ \text{iii.}& \text{Fertilisers are very rich in nutrients like nitrogen, phosphorus and potassium.}& iii.& \text{Manure is relatively less rich in nutrients.}\\ \text{iv.}& \text{A fertiliser does not provide any humus to the soil.}& iv.& \text{Manure provides humus to the soil.}\end{array}$$

(b) Seed drill and Funnel sowing (1 * 2 = 2 marks)

$$\begin{array}{cccc}& \text{Seed drill}& & \text{Funnel sowing}\\ \text{i.}& \text{It is a tractor-driven modern tool used for sowing.}& i.& \text{It is cattle-driven traditional tool used for sowing.}\\ \text{ii.}& \text{It is an efficient method of sowing and saves time.}& ii.& \text{It is a laborious and time consuming method.}\end{array}$$
