B
four

C
six to seven

D
nine to ten

Solution

Soil pH is a measure of the acidity and alkalinity in soils. pH levels range from 0 to 14, with 7 being neutral, below 7 acidic and above 7 alkalines. The optimal pH range for most plants is between 5.5 and 7.0; however, many plants have adapted to thrive at pH values outside this range.
Question 9
1 / -0

Laterite soils are suitable to grow __________.

A
Coffee, rubber and tea

B
Wheat, rice and rubber

C
Jute, maize and millets

D
Pulses, tea and sugarcane

Solution

Laterite soils are good for tea, coffee and cashew cultivation. Laterite soils lack fertility due to intensive leaching. When manured and irrigated, some laterites are suitable for growing plantation crops like tea, coffee, rubber, cinchona, coconut, areca nut, etc.
