Sehaj tried to set up a small kitchen garden in his backyard. However,the soil was sandy and unsuitable for growing vegetables. Within seven days,he solved the problem and started planting seedlings.
$(a)$ Why was the soil in Sehaj's backyard unsuitable for growing vegetables?
$(b)$ What could be the solution he found? Mention any two.

(N/A) Sandy soil has large particle size and poor water-holding capacity. Therefore,it is unsuitable for growing vegetables as it cannot retain moisture and nutrients required for plant growth.
$(b)$ He likely added organic manure to the soil. The two advantages are:
$(i)$ It increases the water-holding capacity of the sandy soil.
$(ii)$ Manure enriches the soil with essential nutrients and organic matter,thereby increasing soil fertility.
